I highly suggest you try the fantastic Rasta Bivy Kitâ„¢ from Alpine Kind Technologies. It has been field tested at altitude (see Muir Hut Study of 2001), and has dozens of stoaked customers... some comments after using the bivvy kit:
"Huhhhhh, fuckin plab"
- gapertimmy
"Yeah, I'll pee in your butt"
- Cpt. Caveman
"Honestly, I love clipping bolts"
- Dwayner
"YOU ARE JUST THUPER!!!! SO THUPER!"
