Bristlecone Bivy

The Bristlecone Bivy provides a waterproof floor with a water resistant upper to protect your quilt from spray and mist. Featuring a large mesh window and long U shaped zipper extending from waist level across the top, allowing for easy entry and exit. Designed to work well with both pyramid shelters and tarps.
  • Large Mesh Panel- No-seeum mesh window over your head provides ventilation.

    Long #3 YKK Zipper- Long inverted U zipper running from waist level to above head, allows easy entry and exit.

    Waterproof ROBIC® Nylon Silicone/UTS Coated Floor- ROBIC® high tenacity yarn and UTS coating provide extra tear strength, abrasion resistance, and it is less slick than a traditional silicone coating.

    Bathtub Style Floor- Reduced seams in the floor for increased weather resistance.

    Pertex Quantum Air Upper- This highly breathable, water resistant fabric features a long lasting DWR coating that outperforms and outlasts other DWR treatments. Increased air permeability reduces condensation while remaining highly wind resistant.

Colorado Trail Tested & Approved

I used this bivy (6’ version) with a Hyperlite Mountain Gear tarp while bikepacking the Colorado Trail last summer. It rained almost every day, so knowing I had this cozy space to retreat to at the end of the day was always fantastic.
Pros: light weight, breaths well, no condensation, plenty of space inside to move around (I’m 5’11 & broad shoulders), durable, versatile (can use it to cowboy camp or under a tarp), set up is quick and easy.
Cons: The material on the bottom is very slippery on my ground sheet (I’m looking to add some silicon dots to the fabric to reduce it sliding on my ground sheet.
All in all this Bivy with a tarp is the best shelter I’ve ever used. I hiked the PCT in 18’ (did not use this shelter system) and no doubt will be using this on my next thru hike or any outdoor adventures.

Great piece of gear

I constantly roll off my pad at night and this bivy completely solved that issue. It’s so nice to be able to sleep through the night and be fully contained.

Bristlecone Bivy, five stars!

I took this bivy out for a Colorado trail bikepack/fastpack mission during this very wet summer with heaps of mosquitos. The mesh is such a game changer, and kept the mozzies out along with rain spray coming in under my tarp. I love how roomy it is (I'm a side sleeper, this is important) and the pad ties on the inside worked great to keep my pad from sliding around. And, it's even lighter than my old bivy which is a tighter fit and has no mesh, rolls up great in my bikepacking sleep kit burrito. I definitely recommend it!
