As effective as a mid-layer as it is as an outer jacket, the KYANITE JACKET M from Arc'Teryx is an insulating jacket for men that provides warmth, mobility and moisture regulation.

Featuring Polartec Power Stretch Pro technology for enhanced abrasion resistance, it adds a brushed fleece lining and reinforced ends. The four-way stretch structure, combined with articulated construction and stretch gussets under the arms, guarantees exceptional freedom of movement . The slim-fitting cut, meanwhile, hugs the body, enabling it to be worn under a hardshell jacket.

In addition to its multiple pockets, this jacket adds a No Slip Zip to prevent accidental opening.
