There are pop-up tents available; the original company being QUECHUA. They now have a few imitators.
Some one mentioned that there are larger versions available. Has anyone seen them? I think they may be military issue only.
I have had a Quechua one for a couple of years. Ideal for the kids in the garden in the summer. I'd be really interested in one that packed down smaller. It's a bit cumbersome to have a frisbee on the back of my bike
