## Description

What Our Gearhead® Experts Are Saying: “The Alpha 4. 0 is my ‘one-and-done’ resort shell for cold months—stretchy Helly Tech Professional keeps me dry, PrimaLoft Black Eco is legit warm without bulk, and the Aerogel Life Pocket actually helps my phone survive frigid lift rides. Fit runs a bit trim in the arms—size up if you layer heavy.”From storm laps to sun breaks, the Alpha 4. 0 is tuned for the rhythm of the chairlift. Helly Tech Professional 2-layer fabric seals out sleet and blower while moving with you thanks to built-in stretch. Low-bulk PrimaLoft Black Eco insulation takes the bite out of single-digits, and when temps climb, H2Flow pit zips dump heat fast. A removable, helmet-compatible hood, adjustable powder skirt, and fully sealed seams keep snow where it belongs. Thoughtful touches—like the Aerogel Life Pocket to keep batteries alive and an integrated RECCO reflector—round out a jacket that disappears into your day so you can focus on the fall line.
