As previewed earlier in a teaser video, outdoor experts Burton team up with both Alpha Industries and Undefeated on a triple collaboration for the upcoming fall/winter seasons. Mixing military and streetwear aesthetics with the rugged outdoor garment technology made for winter wear, the "Trinity" collection promises to bring forth a new level of hype to the mountains or the urban streets. Seen in the lookbook is a variety of outerwear — flight suits, M65 jackets, bombers, N2B coats, as well as pants, goggles, face masks, gloves and boots. Lastly, luggage options like a duffle bag and a new backpack help round out the collection, all with velcro patches for customization. The drop is available now at Undefeated.com and at all Undefeated Chapter Stores worldwide on October 17.
