Phase Pro Men's Helmet

Spin in the perfect fit with the Phase Pro helmet — the Phase platform upgraded with a built-in audio kit and an optional MIPS liner for increased protection. Subtle contouring, perfectly placed Active Matrix vents, and your soundtrack dialed in for the chairlift ride. Premium everyday protection with the works dialed in.

Built-In Audio Kit
Pre-installed audio kit with a low-profile speaker that easily connects to your mobile device. The on-cord remote puts talk and tunes right at your fingertips — no aftermarket speaker install, no shaved foam pads, no zip ties.
Optional MIPS Liner
Available with a MIPS liner for increased protection against rotational forces — the low-friction layer allows the helmet to slide relative to the head during the critical first 10mm of angled impacts.
Hybrid Construction
This unique construction features the best of both In-Mold and Hard-Shell builds. The primary In-Mold construction keeps it light, while the secondary Hard-Shell upper adds durability where it counts and resists dings from sticks, rails, and chairlift racks.
Active Matrix Venting
User-regulated Active Matrix vents let you dial in airflow on the climb or close vents for storm days — the system pulls air through the helmet and over the goggle area to fight fog and overheating.
360° K2Dialed™ Fit System
K2's signature 360° micro-adjustable fit dial wraps the head for even pressure and a glove-like fit. Twist once and you're locked in for the day.
Subtle Contouring
Clean, low-profile shell lines that work with any goggle shape — no awkward pressure points on the forehead or temples, no goggle gap on deep days.
Removable Ear Pads and Neck Roll
Convertible design with removable ear pads and neck roll — keep them in for storm coverage or pull them out for spring park laps and warmer temps.
Cycling Certified
Certified for cycling by the Consumer Product Safety Commission (CPSC) and the European Cycling Standard — one helmet for ski, snowboard, and bike park all year.

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.
