Tested and reviewed for bikepacking use
For the truly minimalist bikepacker, the Helium Bivy is a weatherproof sleeping bag shell. Pertex Shield waterproof-breathable fabric keeps you dry, and the single hoop provides face clearance. Pairs perfectly with a lightweight sleeping bag for sub-1kg sleep systems.
