Crux B1 Scout bivi-bag Bivvy Bag

A glorified sleeping bag cover, the B1 Scout is as simple as a bivi bag gets. It has a drawcord around the face, but you can never completely seal the face area and there is no mesh insect screen. The design may be plain, but the B1 Scout's X-tex fabric is decidedly hi-tech.

X-tex fabric has a woven textile face with a coating to make it both waterproof and breathable, with a 50 denier polyester face. Most bivi bags use a fabric with a microporous membrane or coating. These rely on differences in the partial pressure of humidity in the air in order to breathe. They only work however, when the humidity is in the vapour state: once condensation has occurred they cease to breathe. X-tex fabric is different and it is able to absorb water even in the liquid state and still continue to breathe.

Shelters, Tents & Bivvi Bags:

A good night’s sleep is imperative - whether you're waiting out a storm or spending a night under the stars, our camping shelters and storm shelters offer essential protection from the elements. Lightweight and emergency options available.

A Camping Tarp is a great way to add a layer of weather protection to your lightweight camping setup. When you're out on an expedition in the mountains or hiking over the moors the last thing you want is to carry a heavy tent. Couple a camping tarp shelter with a Bivvy Bag or Bivvy Shelter and you've got an instant camp ready for a good nights sleep.

Another way to enjoy your Camping Tarp is over a camping hammock out in the wilderness with just your warm Sleeping Bag listening to everything the outdoors has to offer at night, a fantastic way to unwind and disconnect.
