Nov 13, 2025We’ve praised the Hestra Heli glove as one of the most comfortable models on the market, and its mitten cousin—designed for folks who need extra warmth—continues the family tradition. Featuring the same ultra-cushy, fleece-backed removable liner as the glove, the Army Leather Heli Ski (often shortened to “Heli”) has kept us cozy down to the mid-teens. While its lack of waterproofing limits its best use to cold, dry environments, the Heli ($185) is nonetheless a super-comfy, dexterous, and well-crafted choice.

Hestra Army Leather Heli
For this season's top models, see our guide to the Best Ski Mittens.
The Hestra Heli falls squarely in the midweight mitten category, keeping hands toasty via a fleece-lined, removable liner packed with G-Loft synthetic insulation. We’ve found that G-Loft fails to match the insulating properties of other synthetic fills such as PrimaLoft, so the Heli doesn’t score as high in this category as heat-hoarding competitors such as the Black Diamond Mercury and the Outdoor Research Mt. Baker II Gore-Tex mitts. It is worth noting that Hestra offers a PrimaLoft Extreme Liner Mitt ($70), which can be purchased separately and swapped with the Heli’s stock liner mitt for those extra-cold days.
Nevertheless, the Hestra Army Leather Heli kept our fingers from freezing down into the mid-teens during our testing days skiing in the Washington Cascades. We also appreciated that, while some ski mittens have glove-style liners on the inside, this model is a mitten through and through, providing space if you want to throw in a handwarmer. (Or, if conditions warm up, Hestra’s removable liner system allows you to swap in a thinner liner.)
When it comes to staying dry, this is a tale of two mittens: The Heli’s back-of-hand side features a 3-layer waterproof polyamide material, but the leather on the palm and thumb absorbs water quickly, and the liner lacks a waterproof insert. Skiers and riders who spend most of their time in relatively warm climates with abundant snowfall, such as the California Sierra, will likely want a ski mitten that keeps them dry at all times; the Heli can’t provide that protection. However, those who frequent cold or high-and-dry resorts—the Rockies in Colorado come to mind—might still be swayed by this mitten’s combination of warmth and comfort. If you want both of those attributes plus full waterproofing, Hestra sells a Gore-Tex version of the Heli Mitt ($230).
By mitten standards, the Hestra Army Leather Heli performs about average in terms of dexterity, but we consider that impressive given its warmth. The flexibility of the leather is a plus, as is the fact that the liner isn’t as thick as the ones found in the Black Diamond Mercury or Outdoor Research Mt. Baker II Gore-Tex—in those models, you lose nearly all finger sensitivity. Not so with the Heli: We can easily grip a ski pole with this mitten, although we still have to take it off for tasks like unzipping zippers and adjusting goggles. It’s also worth noting that the removable mitten liner has an unfinished exterior, so you don’t gain dexterity by removing the shell like you might with models that feature a glove-style liner with a grippy overlay.
We knew right off the bat that this is a superlatively comfy mitten. The Heli doesn’t require any break-in period, and the leather has a buttery handfeel. It’s what’s on the inside that counts most, though: A cloud-like fleece covers the liner’s interior, creating an ultra-soft space for your hands that few competitors on the ski mitten market can match. Hestra designers went the extra mile on the Heli’s wrist leash as well, constructing it with a silky elastic that never irritated our skin. To cap it off, an adjustment strap at the mitten’s wrist allowed us to easily fine-tune the fit as we wished.
The Heli’s palm and most of its thumb are made from a single layer of goat leather. While goat leather is a durable material, the lack of double-layer reinforcements on the mitten brings it down a notch or two in this category. (We haven’t conducted long-term testing on the Heli mitten, but we’ve spent more than 60 days on the mountain in the Heli glove; the glove has held up quite well, suffering merely cosmetic scuffs. Some wearers might also find the white leather a dealbreaker: It becomes discolored after use, and even minor surface-level damage stands out more prominently than on a darker material.
The Hestra Army Leather Heli comes with a tube of leather balm, which helps keep the mittens in fighting shape. Regular applications of the balm (or a similar conditioning wax) are essential for maintaining the strength, suppleness, and moisture resistance of the leather. We’re also big fans of Hestra’s replacement liners, which extend the life of the Heli when its stock liners start to pack out.

Longevity
Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.
PFAS-Free DWR
Durable water-repellent (DWR) finishes can contain PFAS (per- and polyfluoroalkyl substances). These highly persistent “forever chemicals” are used in outdoor gear for their strong resistance to water, oil, and heat, but are linked to environmental contamination and a range of health concerns. A green check mark indicates the product uses a PFAS-free DWR, while a red X means the DWR contains PFAS.
PFAS-Free Waterproof Membrane
The membranes used in waterproof products such as rain jackets, ski jackets, and shoes can contain PFAS (per- and polyfluoroalkyl substances). These highly persistent “forever chemicals” are valued for their resistance to water, oil, and heat, but are linked to environmental contamination and a range of health concerns. A green check mark indicates the product’s waterproof membrane is PFAS-free, while a red X means it contains PFAS.
Responsible Leather
Responsible leather is typically sourced from suppliers certified by the Leather Working Group (LWG), a third-party nonprofit that evaluates tanneries on factors such as water and energy use, chemical and waste management, emissions, traceability, and worker safety, and assigns ratings ranging from Bronze to Gold. A green check mark indicates a product uses responsibly sourced leather, a yellow check mark indicates the brand sources responsible leather for the majority of its products but does not specify it at the product level, and a red X indicates the product does not use responsibly sourced leather.
Recycled Materials
Recycled materials are prevalent in outdoor gear, with nylon, polyester, wool, and down among the most common, but the composition varies widely. A green check mark indicates the product is made with a substantial amount of recycled materials (100% recycled or the core fabric that makes up most of the product is recycled), a yellow check means it contains a moderate to small amount of recycled materials, while a red X means there are no recycled materials in the product.
Bluesign Approved
Bluesign Technologies, based in Switzerland, operates a third-party textile management system that ensures materials are manufactured to strict environmental, chemical, and worker safety standards. A green check mark indicates a product is either a Bluesign Product (contains at least 90% Bluesign-approved fabrics and 20-30% Bluesign-approved accessories) or features a significant amount of Bluesign-approved materials. A yellow check mark means it uses some Bluesign-approved materials but less than the aforementioned category, and a red X means there are no Bluesign-approved materials in the product.
Responsible Manufacturing
This criterion evaluates a brand’s commitment to fair wages, safe working conditions, and reducing environmental impact through certifications and programs like Fair Trade Certified, Fair Wear Foundation, Worldwide Responsible Accredited Production (WRAP), and the Fair Labor Association, while also recognizing brands that manufacture primarily in the U.S. or Europe under strict labor and environmental regulations. A green check mark indicates a brand meets our responsible manufacturing criteria, while a red X means it does not.
Recycled and/or Reduced Packaging
Packaging can add significant waste to outdoor gear purchases, so many brands work to reduce its impact by using recycled materials, incorporating Forest Stewardship Council-certified paper products, and minimizing plastic and paper use. A green check mark indicates a brand uses recycled or reduced materials across all of its packaging, a yellow check indicates moderate or limited use of recycled or reduced packaging, and a red X indicates the brand does not make either of these efforts.
Resale and/or Recycling Services
Resale and recycling programs help keep outdoor gear in circulation longer and out of landfills, ranging from trade-in resale platforms that offer store credit to take-back initiatives that recycle products at the end of their usable life. A green check mark indicates a brand offers both resale and recycling programs, a yellow check mark indicates it offers one or the two, and a red X indicates it offers neither.
Carbon Footprint Tracking
This criterion evaluates whether a brand measures, reports, and works to reduce its greenhouse gas emissions using established frameworks such as the Higg Index, Greenhouse Gas Protocol, or The Change Climate Project. A green check mark indicates a brand publicly reports greenhouse gas emissions data, sets clearly defined reduction targets, and uses established tracking frameworks such as Higg or The Change Climate Project. A yellow check mark indicates the brand tracks emissions and outlines reduction goals but provides limited data, lacks science-based verification, or does not clearly report progress. A red X indicates the brand does not appear to track greenhouse gas emissions or provides so little information that its efforts cannot be verified.
Annual Impact Report
Annual impact reports provide transparency and accountability by outlining a brand’s sustainability efforts across areas such as material sourcing, greenhouse gas emissions, waste, water use, supply chains, and packaging. A green check mark indicates a brand publishes a detailed, brand-specific impact report that closely aligns with our sustainability criteria and leaves little room for ambiguity. A yellow check indicates a brand provides some relevant sustainability reporting but lacks detail in key areas or is covered only briefly within a parent company report. A red X indicates a brand does not regularly publish an impact report.
Wrist Leash
The Heli’s wrist leash is thoughtfully made, and we found it comfortable and convenient. Its large, elasticized wrist loop is soft on the skin and never bothered us when we wore it, and it feels a lot more secure than a loose cord. In contrast to the Outdoor Research Mt. Baker II’s thin, unelasticized leash and the leashless Black Diamond Mercury, the Heli’s design is a true standout.
Carabiner and Grommet Attachment
Each mitten in the pair has a metal grommet just above the wrist, and the Heli comes with a small carabiner to hook them together. The setup is more cumbersome than the built-in buckles found in other ski gloves and mittens; aside from hanging the mittens from a jacket or backpack on a backcountry tour, we didn’t find a reason to use the carabiner at all. And when not in use, the large grommet is an eyesore.
Hestra uses its own numerical sizing system, and the Heli mitten is available in men’s sizes 5 to 12 and women’s sizes 5 to 9. We felt that the women’s size 7 felt close to a true medium, and our female tester enjoyed the slightly slimmer cut of the women’s Heli mitt compared to other mittens she’d worn. (The design minimizes bulk around the fingers, increasing dexterity and comfort.)
Black Diamond Mercury ($140): Warmer, More Waterproof
If you’re considering the Hestra Heli Mitt, it’s worth looking at the more affordable Black Diamond Mercury. For $45 less, the Mercury is warmer than the Heli, with thicker PrimaLoft Gold insulation and a super cozy high-pile fleece lining. It’s also fully waterproof, thanks to a BD.dry membrane, and is overall more durable than the Heli. As a bonus, the black colorway hides wear and tear. But there are downsides to the highly protective design: The Mercury is noticeably less dextrous (gripping a pole with the Hestra feels more secure), and its PrimaLoft is bulkier than the Hestra’s G-Loft and will pack out more over time. For more, read our review of the Black Diamond Mercury Mitt.
Outdoor Research Mt. Baker II ($179): Hardshell for Your Hands
The Mt. Baker is designed with opposite priorities to the Hestra Heli, emphasizing weather protection and durability over comfort. It features a 3-layer Gore-Tex membrane that resembles a burly hardshell jacket, so the Baker is ready for very rowdy and wet conditions. On the other hand, the Heli is comparable to the Baker in terms of warmth, is more dexterous thanks to a supple leather palm (the Baker is crinkly and stiff), and has a less techy look. Both have their place, and a choice should come down to local conditions and which attributes you value. On storm days, you better bet we’re grabbing our Bakers. For more, read our review of the Outdoor Research Mt. Baker II GTX.
Swany X-Cell Mitt ($190): Premium Leather, High-End Warmth
In our opinion, the Swany X-Cell is the consummate leather ski mitten. Like the Heli, it’s soft, supple, and outrageously comfortable, and delivers a high level of warmth—just a notch below the category leaders. Its liner isn’t removable, but the simpler construction is ideal for resort skiers and offers slightly better dexterity for handling gear. You also get full waterproof protection, which helps justify the high price tag. The usual leather caveats apply—slower dry times and less reliability in prolonged wet snow—but for many skiers, the X-Cell’s upscale materials and craftsmanship easily make it worth the investment. For more, read our Swany X-Cell Mitt review.
One of Hestra’s most popular ski mittens, the Army Leather Heli is warm and cozy and features a removable liner for easy laundering and drying. It’s not fully waterproof, though, so we don’t recommend it for skiers who routinely get out in wet conditions.

The Mercury is an ideal mitten for cold-handed skiers, with a cozy interior, powerful insulation, and reliable waterproofing. However, it's on the bulky side for holding onto a ski pole and does not include leashes.

The Mt. Baker offers the height of function, with no-holds-barred waterproof protection and a removable glove liner that works well for standalone use. However, comfort is compromised due to the hardshell-like build, and the mitten is too bulky for most tasks—even holding a pole is challenging.

The Hestra Army Leather Heli Ski is an ultra-comfy conundrum: Its excellently designed interior liner feels wonderful next to the skin, making this mitten a dream to wear—but only in the right weather conditions. The Heli falters in sustained precipitation, and no amount of luxurious fleece can make up for wet hands when you’re on the mountain. Considering its solid durability and dexterity, we wholeheartedly recommend this ski mitten for skiers and riders who frequent cold, sunny, and relatively dry climates. But if you’re heading on a pow-chasing trip, pack a backup pair.
