- How fast does it really set up?
- The pop-up frame opens in about three seconds once you release it. Staking it out and adding the rainfly take a few more minutes.
- Is it waterproof enough for heavy rain?
- It has a 3000mm water column, taped seams and a built-in rainfly, which handles steady rain. Prolonged downpours may still let moisture through the floor.
- Can I stand up inside?
- No. Peak height is 57 inches in the large size, so most adults have to crouch.
- How many people fit?
- The 79 x 79 inch floor fits two adults with gear, or three campers sleeping close.
- Is it good for backpacking?
- Not really. At 8 lb and 27.6 inches packed it suits car camping and festivals better than long hikes.
