At 285g, the Kloke is one of the lightest 3-layer waterproof bivvy bags on the market. It's a highly packable shelter that's ideal for Alpine bivouacs, lightweight bikepacking and adventure racing.

Ultralight and packable for lightweight adventures
Exceptionally waterproof and breathable
Zipped hood closure for extra weather protection

The Kloke uses a ultrafine 10 denier nylon fabric to sandwich the PU membrane. It's one of the lightest 3-layer waterproof fabrics we could find, providing reliable performance for the lowest pack weight possible. This fabric is highly breathable (30k MVTR) which drastically reduces condensation build-up on the inside of the bag.

The Kloke’s zipped closure (with external storm flap) provides extra protection so you can close off bad weather when the clouds roll in. You’ll need to leave a gap of about 6 inches for airflow though, so we’ve used a 2-way zip that lets allows you to position your air hole. (A wet nose is better than hypoxia... or worse! Gulp.)

When it’s time to get up and hit the road again, the Kloke packs back down to a miniscule 20 x 12 cm – smaller if you compress it. It’s so minuscule that you can throw it in the lid of your pack as an emergency shelter when getting benighted looks a distinct possibility – maybe the Cuillin Ridge in a day was a tad ambitious this time!

The Kloke has greater volume than our Hunka bivvy bag so you can use it with a 4-season/alpine sleeping bag, along with your sleeping mat. As a guide, 6ft 4" Product Developer Rowan easily fits into the Kloke with his winter sleep system.

SAFETY NOTE
Always keep the zipper open enough to provide adequate ventilation to prevent suffocation.
