For sale: a First Ascent expedition weight ¼-Zip baselayer top. Made from Polartec Pwoer Dry gridded polyester fleece. The fabric is much like the Patagonia R1 series but has a slightly smaller grid-- about 3/4 the size of the grid on my R1 jacket. Sized to fit as a baselayer and on the snug size, measuring 22" across the armpits (unstretched/relaxed), 29" from the base of the collar to the tail and 36" from the center of the collar to the cuffs. The cuffs are plain with no thumb holes. The zipper is 12" long and the top weighs 9.6oz. Power Dry is fantastic stuff-- warm, very breathable and excellent moisture transfer. This is perfect for cooler weather, layered with a windshirt or rain shell and great for sleep too. In excellent condition with no holes or stains, freshly laundered in tech wash and ready to go. $30 including US shipping and PayPal fees.
