"The prAna Heritage Hoodie pulls its look from prAna's '90s archive and its comfort from a fleece-lined interior. Organic cotton construction and 2x1 rib detailing at the cuffs, hem, and armpits keep the fit close and the warmth in, whether we're layering up before a climb or running errands after. The hood's ribbed lining adds another layer of warmth for cooler mornings at the crag. Gearhead QuoteWhat Our Gearhead® Experts Are Saying:""I've worn this over a base layer on cold approach hikes and kept it on belaying, since the fleece interior holds warmth even when I'm not moving. The rib at the armpits means it doesn't bind when I reach overhead to place gear."""
