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.

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

Sustainability & Care

Product Care Information

Caring For Your DWR
To maintain the high performance of your bivvy bag, we recommend you wash it regularly and re-proof it once or twice a year (depending on usage). This keeps the DWR working at its best, maintaining breathability. Wash it with pure soap or a specialist cleaner (like Nikwax Tech Wash or Grangers Performance Wash) and use a wash-in or spray-on reproofer.

Washing Instructions
Wash on a delicate cycle at 30˚C or hand wash with lukewarm water. Use a technical wash product or pure soap. DO NOT use detergent, fabric conditioners or softeners. Rinse thoroughly in clean water. Line dry or tumble dry on low heat with the zips closed. Use a cool iron to reactivate the DWR.


The Kloke uses a completely PFC-free durable water repellent treatment. PFCs are potentially harmful chemicals that have been found to build up in the environment. We don't like the sound of that so we're working hard to get rid of them.

Recycled Materials
The Kloke's fabric is 100% recycled nylon, made from post-industrial recycled content. This uses up leftover matter from nylon production, as well as fabric scraps from the cutting process, to remake it into brand new nylon fabric!

Active Traveller review the Kloke

"Overall we loved the Kloke. It has become part of our everyday kit list as a result of being so portable. It does need respect and care, but if you do it should be a terrific addition to your kit at a very reasonable price."

Lucas Winzenburg reviews Kloke
The Alpkit Kloke is quite a light shelter that packs down to almost nothing and offers a roomy fit that doesn’t feel the least bit cramped.
I stayed cozy and dry every night that I slept in it and never had any issues with condensation build-up inside. All in all, the Kloke made for an entirely positive introduction to bivvying.
