White interior liner makes finding small items at the bottom way easier Roll-top closure stays sealed in monsoon-grade rain — no exaggeration Backed by Kriega's no-questions-asked 10-year warranty against manufacturing defects Mount inline along the seat or across the seat — both work Modular system: stack multiple US-Drypacks for up to 70 liters of waterproof storage Comes with everything you need to install — no bungees, ratchet straps, or rain covers required Genuinely 100% waterproof — taped-seam liner inside a Cordura shell, no rain cover required Here's the thing about the Us-5 Drypack — it solves the waterproof-storage problem so completely that people genuinely buy them to last decades. 5L of genuinely 100% waterproof storage thanks to the taped-seam internal liner and roll-top closure. The 420D Cordura Lite shell shrugs off abrasion, the aircraft-grade 6061-T6 alloy hooks are bulletproof, and the four-buckle subframe-loop mounting system installs on basically any motorcycle in about 15 minutes. The real magic is modularity — these packs stack together, so you can run one today and add another next month for a bigger system. Stack up to 70 liters total. Comes with everything you need. No bungees, no rain covers, no compromises. We sell these to ADV riders, sport-bike commuters, dual-sport folks, and pretty much anyone who rides in real weather. The modular system is the trick — start with one US-Drypack today, add another next month for a 30L system, scale up to 70L total when you're ready for a multi-day tour. Each one comes with all the hardware you need to install on basically any motorcycle. 10-year warranty. The most over-built piece of soft luggage you'll ever buy.
