Lightweight waterproof bivvy protection for bikepacking and wild camping
A lightweight, packable bivvy bag for bikepacking and wild camping, with waterproof and breathable protection for your sleeping bag.
The Alpkit Hunka is a waterproof and breathable bivvy bag designed for weight-conscious bikepackers and wild campers who want to keep a sleeping bag dry without carrying unnecessary bulk. It packs down small and weighs 330g in this Kelp version, which is 30g heavier than the standard figure listed.
Built for simple, minimal bivvying
The shape is tapered, with a sculpted hood and dual drawcords to help improve water resistance. Fully taped seams add to the weather protection, while the non-zip design keeps things pared back for minimalist use. An integral stuff sack is included for packing it away.
Size and packed dimensions
The Hunka measures 215cm long and 80cm wide at the shoulders, narrowing to 50cm at the feet. Packed size is listed as approximately 13cm x 15cm, which makes it easy to stow when space is tight.
