Bikers do not carry trekking poles! So when talking about UL tents, be aware that you would also have to add a pole system.

I have done 12-day trips at 12,000 feet in a bivy only and have weathered severe storms in one. Depends if you are OK with zipping up in a coffin for several hours or a day. But, as a biker, I assume you would be camping at campgrounds many nights. In this case, you could also get out and sit in the bathrooms for a break, or many some nice neighbor would invite you into their tent or RV. Also as a biker, if you do get wet in the bivy, you are not likely that far from help.


I think you should try to borrow a bivy from someone and try it out a few nights.
