Pinnacle VerticalX™ SuperStrand™ Technology In An Ultra-Packable And Lightweight Package The ultra-packable SuperStrand™ LT Jacket is our lightest, softest, most compressible synthetic down hoodie for four-season warmth. Sharing a name with our VerticalX™ SuperStrand™ technology, the SuperStrand™ LT Hoodie is as light and lofty as 700-800 fill down while retaining warm-when-wet performance qualities. Its ripstop nylon fabric resists abrasions and shields against wind and light precipitation. A unique discontinuous quilting pattern reduces stitching and creates an uninterrupted warmth flow. Additionally, this piece packs into an ultralight average of 10 oz. and compresses down to palm size. The SuperStrand™ LT Jacket provides the best warmth-to-weight ratio, ideal for wearing over base layers or layering under shells for ultimate temperature regulation.
