The Shiga Jacket from Peak Performance is an insulated men's ski jacket designed to provide warmth and breathability on cold-weather outings. It’s part of Peak Performance’s outdoor clothing range and, being non-waterproof, works best in dry conditions or layered under a shell.
Constructed from 100% recycled polyester, this jacket offers a sustainable choice without sacrificing performance. The insulation holds in heat when temperatures drop, while the fabric’s high breathability rating helps moisture escape during activity, preventing that clammy feeling as you move.
The breathability rating of 20,000 g/m²/24 h indicates how many grams of moisture vapor can pass through each square meter of fabric over 24 hours. A higher number means sweat and excess heat are efficiently wicked away, helping you stay drier and more comfortable during extended periods of exertion.
