Scientifically engineered with 3M Thinsulate™ Recycled Featherless insulation to replace natural down, it traps body heat and releases moisture with the optimal warmth-to-weight ratio. This means you can adventure on in subfreezing temps—without the bulk and weight. #featherless #peopleproductplanet #sustainability Photos: @bentommat」12月27日 23時46分
