Glade Boundary MIPS
For this season's top lids, see our guide to the Best Ski Helmets.
Comfort in the Boundary is a mixed bag that results in middling performance. While the interior of the ski helmet features padding that fully wraps your forehead and back of the head, the foam is thinner than that found in models such as the Smith Level MIPS. It isolates you from the Boundary’s MIPS liner and fit system, but not much else. (If you run hot or prefer the reduction in weight this design provides, it might not matter as much.)
The Glade Boundary MIPS’s thin cushioning isn’t securely attached to the shell, so it moves around and exposes the interior’s uncomfortable plastic parts. If you wrench down on the fit system, the strips of plastic that tighten around your head can slide under the padding if you’re not careful. Moving the padding around manually resolved the issue for some testers, but it’s an annoyance.
Finally, the Glade Boundary MIPS' ear flap foam is thicker along the outside and thinner along the interior, in a ring-like configuration; the benefit of this design is that the thinner section allows for more sound to get through, so you can have an easy conversation on the lift or comfortably wear ear buds. The downside, though, is that the ear flaps are small overall and the wider “ring” part can sit uncomfortably around the middle of your ear rather than below it. In one case, the design forced us to wear a balaclava to protect our ears, and we’d prefer much larger ear flaps to mitigate this issue.
If you frequently ski or ride in temps that trend toward “Arctic,” you should probably opt for another ski helmet. The Boundary’s lightweight materials and thin ear padding make this helmet cold and drafty, even with its 10 adjustable vents closed. During a testing day at Grand Targhee Resort in Wyoming, we found ourselves wishing for a full balaclava to wear under the helmet with temps in the low 20s Fahrenheit. While the Boundary’s relative lack of insulation might appeal to backcountry tourers or folks who run warm, heat-seekers should check out a cozier alternative like the Smith Level instead.
As you might gather from the score above, the Boundary performs well in this category. It’s designed with 10 vents on the top and sides that adjust in two batches: You can open the front or back half while keeping the other half closed, or you can leave them all open or closed. This level of adjustment is rare in the category—we’ve tested it in the Smith Vantage and Smith Nexus MIPS but nowhere else—and functions best when you want to release warmth without a rush of cold air on the downhill by opening the rear portion (leaving the front closed).
The helmet also possesses two always-open vents in front on the brim (for ski goggle defogging) and four in the back, also non-adjustable. Its vent sliders are small and are difficult to adjust with gloved hands, but the Boundary’s ability to adapt to varied temps and changing regulation needs is nonetheless valuable. (It’s also simple to remove the ear pads and cushioning at the back of the neck, which come on and off as a single unit.)
The Boundary is built with in-mold construction, in which the exterior shell and interior foam are fused into a single piece (as opposed to a two-piece ABS construction, which is heavier). The design and thin padding keeps weight down, and that lightness is one of the first things we noticed upon putting the helmet on. At 15 oz. on our scale for a size medium (just under Glade’s claimed weight of 15.4 oz.) the Boundary undercuts hybrid in-mold and ABS designs such as the Smith Level MIPS (1 lb. 3 oz.) and the POC Obex MIPS, which we tested alongside it. Backcountry devotees can go lighter with a more focused touring helmet (Smith’s Summit, Salomon MTN Lab, or Giro’s Grid), but the Glade Boundary MIPS is more cushioned, feature-rich, and warmer than those options.
The Glade Boundary’s in-mold style is the least durable of the three helmet construction types (in-mold, hybrid in-mold, and ABS). While it provides benefits in keeping weight and bulk down, the Boundary’s shell is thin—it feels like a bike helmet in hand—and more prone to suffering cosmetic damage or dents from relatively light hits. In fact, our Boundary picked up a small dent along the crown of the shell without any crashes or noticeable impact from a branch or being dropped on the ground (we truly have no idea when the damage occurred). If durability is a priority, we found the similarly priced—and only slightly heavier—POC Obex MIPS (which has a thicker polycarbonate shell and section of ABS plastic at the top) tougher and far more confidence-inspiring on gravity-fueled days.
The rest of the Glade’s design appears hard-wearing. The padding that lines the inside of the helmet and ear pads has a quality feel and hasn’t shown any signs of packing out. And the fit adjustment and vent systems have both worked flawlessly.

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.
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.
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.
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.
MIPS Liner
As with most ski helmets above $150, the Boundary contains a MIPS (Multi-directional Impact Protection System) liner to help lessen the impact of angled crashes. The plastic lattice is placed between the helmet’s shell and liner, and moves separately from your noggin in the event of an impact. It’s an industry-leading system and thankfully doesn’t have a noticeable impact on the Boundary’s fit, ventilation, or comfort.
Adjustable Fit System
The Boundary’s size adjustment comes via a dial system, with the round knob located at the back of the helmet. It’s not a Boa design—which we consider the smoothest-performing option—although we were able to make micro-adjustments while wearing gloves. One downside, though, is that the helmet lacks the option to adjust the fit height-wise. Some models—such as the POC Obex—allow you to shift the dial up or down to better tune the fit to your head shape.
Fidlock Magnetic Buckle
Magnetic buckles cut down on fiddling if you’re wearing gloves and generally operate more smoothly than traditional buckles, so we’re glad that the Boundary has one on its chinstrap. The design promotes a quick learning curve (the buckle slides into place rather than snaps) and allows for fastening and unfastening the strap one-handed.
For this test, we had two folks wear the Glade Boundary MIPS in a size medium, which has a fit range of 55 to 59 centimeters. With head circumferences of 56.5 and 58 centimeters, both testers were able to get a secure fit thanks to the adjustable dial at the back. Although as noted in “Comfort” above, we had a number of complaints related to the padding and size of the ear pads. Otherwise, the Boundary has an average, slightly rounded shape, which should land in a user-friendly middle ground for most wearers. It’s not excessively snug on the sides like we’ve experienced with some brands (Sweet Protection, for example), is a little more rounded than Oakley, and is more in line with Smith and Giro’s standard fit.
Smith Vantage MIPS ($275): Up a Notch in Price and Performance
The Smith Vantage has an eye-watering price, but it backs that up with all-around excellence. Both shells aim for mixed resort and backcountry use, although the Vantage is much more hard-wearing thanks to its hybrid in-mold construction that features ABS plastic throughout the top half of the shell. Both are highly ventilated and have two-stage vents to promote airflow, but we give the clear advantage in comfort to the premium Smith. Even though it’s significantly more expensive than the Boundary and a few ounces heavier, we think the Smith Vantage is the better buy by far. For more, read our Vantage MIPS review.
POC Obex MIPS ($200): Sleek-Looking and Tough
If you charge hard on the slopes or are rough on your gear, the admirably durable POC Obex MIPS is worth a look. While its interior cushioning is less plush than the Boundary (and definitely not as cushy as the Smith Vantage), the Obex’s full polycarbonate shell has a heavier, more substantial feel, impressive for an in-mold design. There’s also a section of ABS plastic at the top for additional protection against cosmetic damage. This helmet is warmer than the Boundary; it has fewer vents and some are covered by plastic on the interior. The Obex is also slightly heavier—and all around less appealing for backcountry skiers and riders—but it’s protective, very well-made, and doesn’t suffer from any of the comfort complaints we had of the Boundary. For more, see our POC Obex review.
Direct-to-consumer Glade makes a strong case with its lightweight and airy yet feature-rich Boundary, which is equipped for crossover resort and backcountry use. But we were let down by the interior comfort, and the thin build wasn’t confidence inspiring for hard-chargers.

A long-standing favorite, this premium helmet is about as versatile as they come: durable, comfortable, feature-rich, and a good balance of warmth and ventilation. You pay a pretty penny, but there’s a reason the Vantage is consistently seen on the slopes—it’s that good.

Sleek-looking and with a sturdy polycarbonate shell, POC’s premium all-mountain helmet is a great choice for hard-chargers. It’s not particularly warm or plush inside, but the materials are built to take a knock.

Is the Glade Boundary for You?
The Glade Boundary MIPS offers wearers a somewhat disappointing mix of high-end, user-friendly features and low-performance attributes. We appreciate its robust loadout with accouterments such as the magnetic buckle, customizable venting, and removable ear flaps. However, unimpressive scores in comfort and build quality mean that this helmet has much less widespread appeal than big hitters from POC, Smith, Giro, and others. (We have to imagine that list of brands is who Glade had in mind when they built the Boundary.) Unless the fit works really well for you and you prioritize a low weight and the aforementioned features, we recommend steering clear.
