Here’s how to fix a rip in your tent.
Put duct tape on the outside, add seam grip to the inside, put on some mosquito netting on the wet seam grip, then put on another layer of seam grip. Once it’s dry, it’ll be stronger than the original tent.
Granted, these are not items you are likely to have on a short climbing trip, but you can take care of it when you get home. On a longer expedition, this may well be repair gear you want to carry.
