SDR D3 Traveller Duffel Bag
It took three years of testing to develop the SDR D3 Traveller Duffel Bag, but the result is definitely worth it. This ultralight workhorse is made primarily from Cuben Fiber, a waterproof material that's four times stronger than Kevlar but weighs about half as much. Designed to fit in a business-class footwell or under an economy class seat, the bag supports a variety of carrying styles, and offers upscale details like YKK Uretek zippers, Petzl aluminium carabiners, anodized aircraft-grade aluminum loops and tri-glides, and Lhasa River stone zip pulls. And should you head out devoid of anything to carry, the entire thing rolls up to the size of a small sweater, making it ideal for hauling back the fruits of your travels.
