Haleine, a French term, translates to 'Breathe' in English. Our most breathable insulating layer to date, the Haleine Hoody is constructed utilizing Polartec® Alpha Direct® 90gsm fleece. This piece provides unmatched warmth out of a sub 5oz ultralight design. This is our first choice for UL backpacking / thru-hiking, layering on the coldest of days in the mountains, and days on the trail where an active insulation is needed most.
