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 bivy you have ever slept in.

I am confident in my Uber Bivy and will back it up with a 100% refund if you are not satisfied.
Just make sure you use the groundsheet and don't abuse it for 1-2 nights.
If not happy, just send it back undamaged and I will refund your money.
It's that simple!

Now the challenge is to find a good storm to sleep in :)

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 while entering ;)

The Uber Bivy also fits VERY large sleeping pads ;)

Trip Reports

Here is the setup and packing of the Uber Bivy.
I wanted to do this outside but I have not had much time. Hopefully this will force me to do it right!
Notice the folding and rolling to get it bag in the bag :)

Here is one of my customers testing his bivy :)

See it at the Whitney Portal Store!
