1 / 3Smith Nexus MIPS Helmet
Pre-order · Ships September 2026
Description
The Smith Nexus Mips is an all-mountain ski helmet built around complete Koroyd coverage, an Exoskeleton that reinforces the side-impact zones, Mips rotational protection, and a BOA 360 dial fit. Smith builds it for skiers who log many days and want protection that holds up season after season.
A hybrid shell pairs a durable hardshell exterior with a lightweight in-molded shell, and complete Koroyd runs throughout to absorb energy while keeping the helmet vented. The 24-vent design adjusts front and rear to regulate airflow, a sweat-wicking, odor-fighting liner keeps the interior warm, and AirEvac venting is built to work with a Smith goggle. The BOA 360 dial tunes the fit one-handed, the Fidlock buckle closes with gloves on, the ear pads come out, and it stays Aleck audio compatible.
This lid suits an all-mountain or resort skier who wants a durable, protection-forward helmet with a dial fit and Smith goggle integration. The Nexus comes in a standard shape and a Round Contour Fit for rounder heads, in sizes S through XL, with most colorways carrying Mips.
A helmet only protects when it fits, so come in and we will size you, dial the BOA to a level, snug fit, and match it to your Smith goggle so the AirEvac venting lines up. Buying online? Measure your head above the ears and we will confirm the size before it ships.

Smith Nexus Mips Ski Helmet
Nexus family · 26/27
Technology
Complete Koroyd
Welded co-polymer tubes that crumple on impact to absorb energy while staying open for airflow; the Nexus runs complete Koroyd coverage throughout the helmet.
Exoskeleton
Added reinforcement built into the side-impact zones of the shell to enhance protection there, on top of the Koroyd coverage.
Mips
A low-friction layer inside the helmet that lets it move a few millimeters on an angled impact, designed to reduce the rotational forces that reach your head.
BOA 360 Fit System
A dial-driven cable cradle that tightens evenly around the whole head for one-handed micro-adjustment on the move.
AirEvac Ventilation
Smith’s goggle-integration venting that channels warm, moist air up and out of the goggle interface to cut lens fogging.
Features
- ·Hybrid shell with complete Koroyd coverage for energy absorption and airflow
- ·Exoskeleton reinforcement in the side-impact zones
- ·Mips for rotational-impact management (select colorways offered without Mips)
- ·BOA 360 dial fit for one-handed micro-adjustment
- ·24 vents with front and rear adjustable airflow
- ·AirEvac goggle integration for fog-free lenses
- ·Fidlock magnetic buckle and removable ear pads
- ·Aleck audio compatible; ships with a Smith helmet bag
- ·Also offered in a Round Contour Fit for rounder head shapes
The Smith Nexus Mips sits at the protection-forward end of Smith’s all-mountain line, and its idea is layered impact management: a hybrid shell over complete Koroyd coverage, with an Exoskeleton reinforcing the side-impact zones where a shell alone can be thin. Complete Koroyd does the absorbing — welded co-polymer tubes that crumple to take energy and stay open so the helmet keeps breathing — and Mips manages the rotational forces an angled impact can send to your head. Certification is ASTM F2040 plus CE EN 1077:2007 Class B, the all-mountain standard.
Fit and venting come from Smith’s adjustable hardware. The BOA 360 dial micro-adjusts the cradle around your whole head one-handed, so you can snug it over a thin hat or ease it off late in the day without stopping. Twenty-four vents adjust front and rear to regulate airflow, AirEvac routes warm air out of the goggle interface to keep a Smith lens clear, and the Fidlock buckle closes one-handed with gloves on. A sweat-wicking, odor-fighting liner and removable ear pads round out the interior, and it ships in a Smith helmet bag.
What you pay the Nexus premium for is the Exoskeleton side-impact reinforcement on top of the same complete-Koroyd, BOA-360 platform as the Smith Vantage 2. The Vantage 2 costs less and actually carries more vents — 40 to the Nexus’s 24 — but it does not add that side-impact reinforcement. At 550g in size M it matches the Vantage 2’s weight, so this is not the lid to chase if you want something lighter; Smith’s 400g Method Mips is that helmet, with zonal Koroyd and a simpler fixed-vent, no-dial setup. And if a round helmet has always pressed on your forehead or the back of your head, buy the Round Contour Fit version instead: same helmet, a shape tuned for rounder heads.
Safety — read this
No helmet prevents all injury. The Nexus meets ASTM F2040 and EN 1077:2007 Class B; Koroyd, the Exoskeleton, and Mips are impact-management systems, not guarantees. Replace any helmet after a significant impact even if it looks undamaged, and make sure the BOA dial holds a snug, level fit before you ride.
Strengths
- +Complete Koroyd coverage absorbs impact energy while staying ventilated
- +Exoskeleton adds reinforcement in the side-impact zones
- +BOA 360 dial micro-adjusts fit one-handed on the move
- +AirEvac venting routes goggle fog out of the lens interface
- +Fidlock buckle closes one-handed with gloves on
Best For
All-mountain and resort skiers who want a dial fit, complete Koroyd, and added side-impact reinforcement in one helmet.
Limitations
- −Costs more than Smith’s Vantage 2 lid
- −At 550g in size M, not a light helmet
- −24 vents — fewer than the Vantage 2’s 40
- −Aleck audio system sold separately
Not For
Skiers who want a lighter lid or more vents for less money — the 400g Method Mips or the 40-vent Vantage 2 fit that better — and anyone whose head shape needs the Round Contour Fit, which is a separate version.

Common Questions
- Does the Smith Nexus have Mips?
- Most colorways include Mips. Select colorways come without Mips at a lower price.
- What is the Exoskeleton on the Nexus?
- It is reinforcement built into the side-impact zones of the shell to add protection there, on top of the complete Koroyd coverage.
- Does the Nexus have a dial fit?
- Yes. It uses the BOA 360 dial to micro-adjust the fit around your whole head one-handed.
- Can I get the Nexus for a rounder head?
- Yes. It comes in a Round Contour Fit tuned for rounder head shapes, alongside the standard fit.
- Nexus or Vantage 2 — which should I buy?
- Both run complete Koroyd, a BOA 360 dial, and Mips. The Nexus adds the Exoskeleton for side-impact reinforcement; the Vantage 2 costs less and carries more vents. Want the added side-impact protection, buy the Nexus; want more airflow for less, the Vantage 2.
