Our Take:
4.6/5

Smith’s top-end Nexus MIPS helmet ($365) lives up to its sky-high price tag—an impressive feat. The helmet offers premium cushioning and comfort, a durable and protective build, and checks just about every feature box. The cozy interior keeps you warm on frigid days while the generous adjustable vents keep air flowing on an inbounds hike. We found the helmet too heavy and bulky for big days in the backcountry, and you can certainly save some cash without giving up much in terms of comfort and performance, but it’s hard to nitpick the all-round excellence of the Nexus.

Pros

Best-in-the-market comfort with premium padding and a highly adjustable fit system.
Hybrid in-mold construction is durable and reasonably lightweight.
Includes all of Smith’s safety features, such as full-coverage Koroyd and a MIPS liner.

Cons

The price.
Feature-rich and durable build adds weight (a problem if you’re hauling it into the backcountry).

For this season's top lids, see our guide to the Best Ski Helmets.

The Smith Nexus MIPS earns top marks for comfort, featuring high-end cushioning and soft materials without going overboard on the thickness of the padding. To aid with ventilation, the top portion of the interior is largely a soft, mesh fabric, but there’s a checkerboard-patterned patch of padding above the crown of your head for extra comfort. The magnetic chin strap is well-cushioned, and generous padding in the ear pads and along the back prevent any interference from the adjustable fit system.


Speaking of the fit system, the premium Boa setup incorporates thin wire—rather than thicker, hard-plastic straps found on cheaper designs—that essentially eliminates pressure points. The Boa system wraps fully around your head (another benefit of the Nexus’s premium build, as cheaper models will only go halfway or 270° around), cinching evenly and securely. Fit also plays a big role in comfort, and the Smith Nexus MIPS comes in four sizes. (More on fit below.)

One of the reasons to pay more for a ski helmet is to get closeable vents. The Nexus has a two-stage adjustment system controlling 18 total vents at the front and back of the helmet. Shutting the vents completely shields you from the cold—I’ve worn the Nexus without an additional balaclava in temperatures down to the single digits and been plenty warm (on those days, I was active and accessing hike-to inbounds terrain but still had lengthy breaks riding the lift). For most resort skiers, the Nexus should be more than warm enough (thicker interior padding would reduce its versatility on warm days or for end-of-season riding as you’d likely overheat).

With 24 total openings, the Nexus is a highly ventilated build. Among resort-oriented lids we’ve tested, only the latest variation of the Smith Vantage 2 (a whopping 40 vents) and the Sweet Protection Switcher MIPS (26 vents) have more. The Nexus features two permanently open vents along the helmet’s brim to aid in airflow for your goggles. Another 18 adjustable vents dot the front, sides, and top of the helmet. Two dials control the vents in the front and top zones of the helmet separately, allowing you to tune the amount of airflow (opening the vents at the back are great for cooling off while avoiding brain freeze). The dials are glove-friendly and have a two-stage design where they lightly click into place at the halfway point if you want to only partially open them up. Finally, there are another four permanently open vents at the back of the helmet to help further regulate your temperature.  


I’ve found the adjustable ventilation system really useful on active days at the resort where I ride the lift, hike 15-30 minutes, ski down, and repeat. On spring days, I’ve occasionally run a little warm and wanted to remove the padding (the ear pads are removable but it’s a pain); overall, though, the Nexus strikes a versatile balance between warmth and ventilation.

The Nexus’s weight falls roughly in the middle of the spectrum for resort-oriented helmets—Smith lists the Nexus at 1 lb. 3 oz. (I weighed my size medium at 1 lb. 4.1 oz. on my home scale). You can save 4 ounces or more with a trimmed-down model like Smith’s Method, but with compromises in durability and features like adjustable vents. Most helmets with similar constructions—hardwearing ABS plastic along the top and thinner in-mold plastic at the sides—weigh about the same, including the popular Smith Vantage 2 (1 lb. 2 oz.).


The Nexus’s listed weight, however, doesn’t tell the whole story. Thanks to its cushioning and premium fit system, the helmet sits snugly and securely on my head. Unlike some lighter-weight models that make me feel a little more vulnerable while skiing fast at the resort, the Nexus’s beefier design is more confidence-inspiring without ever feeling heavy on my head. Bulk is a similar story: It’s reasonably low profile and I had zero complaints wearing it for resort days. But if you’re thinking about toting the Nexus in a pack for touring, there are lighter alternatives. As a 80/20 resort/backcountry lid, however, the Nexus is perfect.

The Smith Nexus has a hybrid in-mold construction, which means it blends an in-mold build (common on bike helmets and lightweight ski designs) with hardwearing ABS plastic. It’s a best-of-both-worlds concept—keeping weight and bulk in check while retaining a lot of the toughness needed to fend off dents and cosmetic damage. The Nexus takes the hardwearing element even further by expanding the ABS plastic coverage lower along the sides and back of the helmets (most hybrids are in-mold-only along the lower half, including Smith’s mid-range Level). As such, the Smith Nexus MIPS is a little more durable than most hybrid designs, only scoring a little below full-ABS plastic helmets that are built for park use.


Unsurprisingly, the rest of the helmet is built to last. The Boa dial functions flawlessly and the cushioning is resistant to packing out. Barring a big impact (it’s always wise to replace your helmet after a big crash or collision), this helmet should have a healthy lifespan.

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.

MIPS Liner
In short order, MIPS (Multi-directional Impact Protection System) has gone from unknown to widely available in the ski helmet market. The system consists of a plastic layer inside the helmet—sandwiched between the shell and the liner—that moves separately from your head in a fall, reducing rotational forces on the brain in an angled impact. In the Nexus, the liner is tucked away under the padding and goes completely unnoticed.

Koroyd
Koroyd is another safety feature that’s found on many mid-range and high-end Smith helmets. The honeycomb design is made of a series of small tubes bonded together that fit between the hard plastic shell and foam interior. The tubes crumple on impact, absorbing energy while allowing air to flow through the straw-like openings. The Nexus features the most Koroyd of any Smith lid, covering the entirety of the helmet’s sides and top.

My head measure 58 centimeters in circumference, which means I usually wear a size medium in Smith helmets (listed fit range is 55-59cm). I tested the Smith Nexus MIPS in a medium, granting me a snug, even fit, and thanks to the high-end Boa dial at the back of the helmet, it was easy to make adjustments. I also found it easy to take the Nexus MIPS on or off thanks to the magnetic buckle that allows for one-handed operation.

Smith Vantage 2 MIPS ($295): The Do-It-All Lid
Smith’s Vantage 2 MIPS takes the Nexus’s comfort and durability, but lowers the overall weight and price, making it a good option for mixed resort and backcountry use. Like the Nexus, the Vantage has hybrid in-mold construction, a well-cushioned interior (although not as plush as the Nexus’s), and a Boa adjustment system. It also has the same safety-oriented features: MIPS technology and large sections of the impact-absorbing Koroyd honeycomb. That said, the Nexus is incrementally better in terms of durability (with greater use of hardshell plastic) and comfort (with more premium padding). But we give the nod to the Vantage if weight is an important consideration. For more, read our Smith Vantage 2 review.

Sweet Protection Switcher ($285): Hardshell With a Polarizing Fit
Moving outside of Smith’s lineup, Sweet Protection has made a name for itself with sturdy and feature-rich helmets, and the Switcher is a top-end offering. First, the similarities between the two: the Switcher and Nexus both offer above-average durability thanks to their hybrid in-mold and ABS shells (the sections of ABS plastic at the top and sides on both are hardwearing and dent-resistant). And both include magnetic buckles and are well-ventilated, with many openings in the shell and the ability to open and close most of them. But the Nexus takes the clear lead with two fit shapes (the Switcher only comes in one and it’s narrow) and far plusher padding along the interior. We found unless the Switcher fits you really well, it can be uncomfortable. To learn more, see our Switcher MIPS review.

It’s rare that we’d call a nearly $300 helmet “worth it,” but it’s hard to argue that the updated Vantage 2 MIPS isn’t worth its price tag. It has just about everything you’d want in a well-rounded bucket, although you might find more value in a cheaper helmet if you don’t hit the hill that often.

This helmet’s function-first looks make it stand out in a crowd, but the Switcher packs a punch. Its hybrid shell is sturdy, and you get full control over 22 vents. The one hangup is the interior: its narrow shape will limit comfort for some, and the minimalist padding isn’t our fave.

Is the Smith Nexus for You?

The Nexus is hands down the most comfortable ski helmet we’ve tested. In particular, resort skiers who frequently get out in cold temperatures will appreciate its warm, cozy interior that seals out the frigid weather with large ear pads and adjustable vents. And when temperatures warm up or you start breaking a sweat while hiking to your favorite powder stash, you can open up those 18 vents to help cool off. That level of comfort and adjustability is nice when you’re wearing a helmet all day riding lifts and skiing fast, but it’s probably overkill for occasional use or days in the backcountry, when it’ll spend a lot of the time in your pack. If, however, you value protection, warmth, and a high-end build, it’s hard to beat the Smith Nexus MIPS.
