Arc'teryx Kyanite Lightweight Jacket

The Kyanite Lightweight Jacket is Arc'teryx's everyday Polartec Power Stretch Pro fleece, built around a 248 gsm four-way stretch face with a brushed polyester interior. At 280 g (9.9 oz) it sits between a baselayer and a true mid-layer: warm enough alone in 50-65°F weather, breathable enough to layer under a shell during high-output use without overheating.

The 2026 lineup added Tatsu, a flat olive green that reads as tactical without crossing into the LEAF (Law Enforcement and Armed Forces) catalog. That matters for daily wear. Sized true, the jacket fits trim through the chest and arms in the recognizable Arc'teryx silhouette. Sized up one, the dropped hem and longer torso make it a credible cover garment for an IWB or appendix setup, the No Slip Zip front opens fast enough for a one-hand sweep, and the four-way stretch does not bind on a draw.

Arc'teryx sleeves notoriously run long across the catalog. The Kyanite Lightweight is a noticeable exception: the Tanica stretch-bound cuffs sit closer to the wrist than the sleeve length would suggest, so the extra inch of fabric reads as relaxed rather than overhanging. Two zip hand pockets with laminated zippers, a mid-height collar, and an anti-odor finish round out the feature set. Fair Trade Certified sewn.
