Gently used men's small/medium Burton AK Hybrid Jacket / Mid Layer. The sizing has worn off but its a medium if you like more of a slimmer fit, small if you like more of a relaxed fit. Measurements 21.5" Chest, 28" shoulder to hem. Excellent used condition! Only real flaw is some wear on the AK logo on the front. Maximum warmth meets minimal weight in a tech fusion of insulation plus Polartec® Honeycomb High Loft® fleece. The combination of highly breathable fleece and insulation is the ultimate recipe for the technical, layerable warmth of the men’s Burton [ak] Hybrid Insulator. The Polartec® Honeycomb High Loft® fleece offers warmth without weight, high breathability, and fast-drying action that, when paired with zonal mapped stretch insulation, equals versatile midweight warmth. The top-down result is a light yet warm layer for long backcountry tours, stop-and-go sled missions, or overnight epics that involve sleeping in huts, yurts, or snow caves. https://www.burton.com/us/en/p/mens-burton-ak-hybrid-jacket/W19-149771.html
