Colorado-based accessories brand Winter Session has released a lookbook and video for their current Fall/Winter 2013 collection. Shot in nature, the lookbook complements the brand’s use of domestically-sourced and environmentally-conscious materials. Using waxed canvas and vegetable-tanned Horween leathers, the brand aims to make carry goods that are thoughtful, durable and responsible. Founded by husband and wife duo Roy Katz and Tanya Fleisher, each item is handmade in Denver, Colorado. Peep the lookbook and video and check out the full collection here.
