Highly Technical, Absurdly Comfortable

The Kyros edition of the A5 - Stretch Alpha Sweater, the K5 - Aptus Jacket delivers the best of both worlds by combining light, stretchy, and comfy construction with long-lasting durability and heat-packing insulation. Dynamic three-layer construction wicks up moisture and transports it out while hanging onto warmth, and the wind- and water-resistant softshell pairs with an insulated, adjustable hood to ward off nasty weather.

1st Layer Wicks

Double-knit Verso Weave™ fleece provides a blanket-soft feel and uses a circular grid pattern to create air channels, keeping you dry by funneling sweat up to the second layer.

2nd Layer Insulates

Polartec® Alpha® Insulation takes the hot sweat sent up from the first layer and then hangs onto the heat to keep you toasty while kicking the moisture up to the third layer.

3rd Layer Protects

The third and outermost layer uses a durable water repellent (DWR) finish to seal out freshly shed sweat and light rainfall, and features a durable softshell design with 4-way stretch to ward off winds and keep you mobile.

Easy-Fit Coverage

Stretchy, adjustable, and designed to go over climbing helmets, the hood ensures versatile fitting options when you need extra insulation and weather protection.
