Topo Designs Down T-Shirt - Mens - Size Medium Topo Designs released this amazing down t-shirt as a part of their limited-run collection expanding the brand’s reach while staying true to its colorful roots. Topo Designs joined forces with two of Japan’s most celebrated niche outdoor brands, Nanga and Natal Designs The Down T-Shirt is a design most aren't likely familiar with, but it’s been a signature piece of Nanga’s lineup for decades (the brand is 74 years old, after all). It features a nylon micro ripstop outer layer, a duck camo printed interior, and is filled with Ultra-Dry Down to ensure peak performance in varied conditions. Best of all, it stuffs into its own carrying sack for easy travel/use as a pillow when backpacking. I love this jacket. It has been in my closet for years. It has exclusively been worn for lounging around the house during cold months. If I had not outgrown it, this jacket would stay in my collection forever. Incredibly cool. Incredibly rare.
