Pack too heavy? Tired of carrying that heavy tent?

I designed the waterproof / breathable Uber Bivy after a very cold night during a Mt. Whitney winter rescue.
It has lots of room and is the most comfortable and dryest bivy you have ever slept in.

NEW! Sectional poles (17" sections) that are easier to pack :)

Since this is not my day job and I'm also a mountain rescue volunteer the shipping delay could be a few weeks.

My first set of pictures with my daughter did not really show the size of this tent/bivy.
So I asked my friend (6' 9") and his wife to model my bivy sacks for the photos shown here.

WARNING ! RSO (Rapid Sleep Onset)

The Uber Bivy is VERY comfortable! People have fallen asleep just from entering!

The Uber Bivy also fits VERY large sleeping pads

Trip Reports

Here is the setup and packing of the Uber Bivy.
Notice how I fold and roll to get it back in the bag.
This was made before I switched to sectional poles that are much easier to pack.

Customer water test of the Uber Bivy.

See it at the Whitney Portal Store!
