Pop up tents come in various setups suitable for 2 to 8 people. Regardless of the tent’s capacity, one thing to check is the number of doors and windows the tent has.
Two doors are desirable even for the smallest, 2-person tents, as each occupant will have their own entry and exit way. If you opt for a single-wall tent, check the number and position of the vents – ideally, the tent should have both top and bottom vents for cross-ventilation. If that’s not possible, floor level vents are desirable, as they’ll keep you cooler in hot weather.
Double-wall tents usually have windows, but if you aim for utmost ventilation, go for a model with mesh sides and top. The rainfly typically provides adequate protection from wind and rain, and you won’t have to bother about condensation.
