The OverBoard TrekDry 20L is a rugged, waterproof backpack designed for those who need full protection for their gear in wet and harsh environments. With an IP66 waterproof rating and a versatile 3-way roll-top sealing system (top, side compression, or messenger style), it offers a completely secure barrier against water, mud, sand, and dust. Internal grip strips help maintain a watertight closure at all times.

Made from double-laminated reinforced PVC tarpaulin with high-frequency welded seams, the backpack is exceptionally tough and built to last. Comfort features include padded shoulder straps, a ventilated back panel with airflow design, a removable padded hip belt with quick-access pockets, and an adjustable sternum strap with integrated whistle buckle.

The TrekDry 20L is hydration-compatible, featuring a dedicated pocket for a 2L reservoir with Velcro attachment and a clip for the mouthpiece hose. Other smart details include a front bungee cord system (with an alternate grey cord included), two large side mesh pockets, internal zippered pocket, purge valve for compressing the bag, and D-rings for accessory attachment. There's even a Velcro strap for attaching the backpack to rolling luggage.
