More than just a base layer, the Alpha half-zip pullover is a technical garment designed to support active women through every adventure, from snowy trails to rocky climbs, ski slopes to forest runs.Â
At its core lies Polartec® Alpha™ insulation, an innovative fabric technology that delivers intelligent thermal regulation. Unlike traditional insulation that traps heat uniformly, Alpha™ adapts in real time to your activity level. It keeps you warm when you’re still, and releases heat and moisture as soon as you pick up the pace , ensuring consistent comfort without overheating.
Its lofty fibers and mesh core provide dynamic breathability, moisture resistance, and fast drying, even during intense activity. Lightweight, stretchy, and ultra-packable, it slips easily into your backpack and becomes a discreet yet essential companion in all conditions.

How to take measurements
1 - Sleeves
Place your hand on your hip, elbow bent at 90 degrees. Start behind the neck at the middle and reach the shoulder, then go down to the wrist.
2 - Chest Size
Place your arms by your sides, inhale and measure the circumference. Make sure to go between the shoulder blades and around the largest part of your chest while keeping the tape parallel to the ground.
3 - Waist Circumference
Measure the narrowest part of the torso — where you are able to bend or usually wear your pants. Keep the tape parallel to the ground and append the length of one finger to the measurement.
4 - Hip Circumference
Stand up straight, feet placed together, and measure at the thickest part while keeping the tape parallel to the ground.
5 - Inseam
Measure pants that fit you well between the crotch and the waist. Use pants with a standard rise versus low-rise pants. This measurement is rounded to the nearest centimeter/inch.
Size charts refer to body measurements rather than product measurements.
