MT Bivy

The Ultimate Stand-Alone & Shelter Companion for Lightweight Hikers

Tipping the scales at just 290g, the MT Bivy is engineered for UL hikers who want to cut weight without sacrificing comfort or protection. Made from soft, highly breathable waterproof Tyvek fabric with Dyneema-reinforced stress points, it serves as both a protective sleeping bag cover and a standalone minimalist tent.

Thanks to its dual-layer zipper and breathable mesh, you can stay fully bug-free while preventing internal condensation even on humid trail nights. Using the integrated top bungee cords, simply tie off to your trekking poles or nearby trees to expand interior headroom—giving you enough space to read or check your phone comfortably before calling it a night. Pair it with a floorless shelter or use it solo under the stars.

When bike packing, every cubic centimeter in your seat bag or frame bag counts. At only 290g, the MT Bivy rolls down exceptionally small while providing rugged protection against rain, mud, and trail debris.

Crafted from durable, highly breathable Tyvek and reinforced with Dyneema at critical peg-down points, it’s built to handle tough outdoor environments. The wide waist-length zipper makes slipping in and out effortless, even after a long day in the saddle. No trekking poles? No problem—simply anchor the apex bungee cords to your bike frame or a nearby tree branch to lift the fabric off your face. Combined with an ultralight tarp, it forms the ideal, low-profile bikepacking sleep system.
