Ski tours, fall mornings at camp, chilly days bouldering – the warmest Kyanite’s thermal performance, durability, and soft comfort let it shine as a midlayer or standalone. Polartec Power Stretch Pro has a nylon face for abrasion resistance, and its four-way stretch combines with articulated patterning for exceptional freedom of movement. The streamlined fit layers easily under a shell, a low-profile ScubaHood adds warmth, and the soft brushed interior wicks moisture.

Note: Arc'teryx sizes are intended to fit the above body measurements. If your measurements are between sizes, select a larger size for a looser fit or a smaller size for a tighter fit.
Sleeve — With arm relaxed at your side and slightly bent, measure from center back neck, across shoulder to elbow and down to wrist.
Bust — With arms relaxed at your sides, measure under your arms, around the fullest part of your bust.
Waist — Measure around your waist at the narrowest part.
Hip — Standing with feet hip width apart, measure around your hips at the widest part.
NEXT-TO-SKIN — The most streamlined fit from Arc'teryx. Patterned to keep material as close to the body as is comfortably possible to enhance moisture management, thermal efficiency, and fit comfortably under layers.
FITTED — Patterned to stay close to the body through the chest, waist, hip, and thigh. Its low profile eliminates bulk, moves with the body, and fits comfortably under outer layers.
REGULAR — Cut comfortably throughout the chest, waist, hip, and thigh. It allows freedom of movement, provides shape, and layers comfortably under our regular and relaxed fit shells.
RELAXED — Cut loosely through the chest, waist, hip, and thigh. Relaxed without sacrificing structure and clean lines, it offers comfort and freedom of movement with a more casual look.
OVERSIZED — The most generous fit is cut loosely throughout the entire body. Dropped shoulders and wide sleeves provide freedom of movement while offering drape and structure for a contemporary look.
