From the manufacturer:
Versatile. Minimal. Unsinkable.
The Nirvana Self-Bailing is designed to keep you charging down even the rowdiest rapids, with the perfect blend of stability and durability.
The Self-Bailing design excels at minimizing weight, setup complexity, is easier for constant scouting, and is faster for self-rescue when compared to a spraydecked packraft. Featuring our 840d DuPont™ Kevlar® Aramid-Nylon Blend reinforced floor system, Leafield D7 valves, and internal tie-downs (in the TiZip version), the Nirvana Self-Bailing is designed for all of your water-accessed adventures – all the features you need, nothing you don’t.
At 9.2lb (4.2kg) and rated for Class I-III Rivers, the Nirvana Self-Bailing packs down to the size of a sleeping bag, making it perfect for backcountry fishing and hunting trips, hiking or bikerafting into remote runs, or any time you want a minimalist setup, but maximum opportunity for adventure.
