Stash Men's Helmet

Built for low-profile freeride missions, the Stash helmet pairs in-mold construction with a 360° K2Dialed™ Fit System, passive venting, and a removable full-wrap liner — everything you need for laps in the trees without bulk getting in the way of your goggles or your style.

In-Mold Construction
K2's lightest helmet construction bonds the shell directly to the EPS foam for a low-profile fit that won't fight your goggles or sit too high on your head. Less bulk, less weight, less distraction on the way down.
360° K2Dialed™ Fit System
K2's signature micro-adjustable fit system wraps the entire head in an intricate dial web for even pressure distribution and a glove-like fit. Dial it in once and forget about hot spots.
Passive Channel Venting
Integrated vents work with natural airflow to dump heat on the skin track or the lift line — no moving parts to fiddle with, just open vents that breathe.
Removable Full-Wrap Liner
Same coverage as K2's full-wrap liner but can be easily removed, leaving the fit system and minimal padding to accommodate a thin beanie under the helmet or for maximum ventilation on warm days.
Convertible Design
Strip the liner and ear pads for a lower-profile spring setup, or keep them for storm coverage and backcountry warmth — one helmet, two seasons of dialed-in fit.
Cycling Certified
Certified for cycling by the Consumer Product Safety Commission (CPSC) and the European Cycling Standard — grab the helmet for summer laps at the bike park without buying a second one.

Sizing

Sizes
S, M, L/XL
Size Reference
Measure head circumference 1" above eyebrows; match to size chart on K2 site for exact fit
Liner Cleaning
Remove the ear pads and neck roll and hand-wash the liner with mild soap and warm water. Air dry completely before reinstalling — trapped moisture causes odor and breaks down the EPS foam over time.
Shell Cleaning
Wipe the outer shell with a damp cloth and mild soap. Avoid solvents, petroleum-based cleaners, and aerosol sprays — they degrade the polycarbonate shell and can attack any integrated tech layer.
Storage
Store in a cool, dry place away from direct sunlight and heat sources. UV and trunk heat degrade the shell glue and EPS over a season or two. A helmet bag protects the finish.
Replacement
Replace the helmet after any significant impact — even impacts that don't show visible damage can compress the EPS. Most manufacturers, K2 included, recommend replacement after 3-5 years of regular use even without a crash.

S – L/XL Men's Low-Profile · Passive Vent
📐 Find Your Fit
Size Head Circumference
S51 – 55 cm
M55 – 59 cm
L/XL59 – 63 cm

Helmets are sized by head circumference (cm) — wrap it just above your eyebrows, around the widest point of your head. If you're between sizes, size up for comfort. The 360 K2Dialed fit system fine-tunes the fit after buckling. Compatible with most ski goggles — low-profile shape works with K2 goggles and most other brands.

🔩 Component Breakdown
In-Mold Construction
In-mold construction fuses the EPS foam liner directly to the polycarbonate shell — lighter weight and better impact dispersion than traditional hard-shell helmets. Premium look and feel with modern protection.
Low-Profile Freeride Design
Low-profile freeride design — keeps things discrete without bolt-on visors or chunky ventilation sliders. Modern sleek look that doesn't look like a "mushroom" on your head.
360 K2Dialed Fit System
360 K2Dialed fit system wraps the entire head with a simple twist of the dial. Micro-adjustable on the fly for precise fit. Compatible with most hairstyles and head shapes.
Passive Venting
Passive venting (no adjustable sliders) — designed for cold-weather and deep-day skiing where consistent warmth is key. Air channels move heat without active controls to fiddle with.
Removable Liner
Removable liner for washing and climate control — peel out for warm spring days, keep in for deep winter. Liners also allow for fit adjustments as the helmet breaks in.
Lightweight Freeride Profile
Lightweight freeride profile — peak-to-park versatility with minimal head fatigue on long ski days. Discreet look that doesn't compromise on protection.
Goggle Compatibility
Compatible with most ski goggles — the low-profile Stash shape works with K2 goggles and most other brands. No goggle gap issues when wearing a beanie or balaclava underneath.
Best For: Freeride / Peak-to-Park
Per the page, the Stash is best for freeride — "from the peak to the park and everything in between." No bolt-on visors or chunky sliders — keeps things low-profile and discrete.
