What Our Gearhead(R) Experts Are Saying:"I packed this for a three week expedition where checked bags took a beating on every transfer, and the 800 denier fabric never showed a mark. The oversized wheels rolled over gravel and mud at the trailhead like it was nothing."The Subterra Wheeled Duffel Bag from Thule carries the load when a trip stretches into weeks and gear starts piling up fast, built for expeditions that demand more room and more durability than a standard bag can offer. A 75 liter capacity swallows clothes and equipment alike, kept organized with an internal divider and compression straps so nothing shifts loose over rough roads and rougher trails. Tough 800 denier nylon with a PFC-free DWR finish shrugs off light rain and boat spray, while a polycarbonate back panel absorbs the impact of baggage handlers and bumpy transport. Oversized wheels and a telescoping handle roll over uneven ground without hesitation, and a quick access top pocket keeps essentials within reach whether the main compartment is packed tight or wide open.
