We partnered with Truce Designs to create a one-a-kind Drop-Liner Backpack built from Slingshot prototype kites and wings. Handcrafted in Portland, Oregon from repurposed Slingshot prototype kites and wings, the SDL Backpack gives high-performance materials a second life as a rugged everyday essential. Made from the same fabrics engineered to handle wind, water, and impact, it blends durability with minimalist design. Because each bag is individually sewn from reclaimed materials, every backpack is completely unique.
