What counts as an ultralight tent?

Generally a shelter that gets your per-person trail weight under roughly two pounds. True ultralight models often use trekking poles instead of dedicated tent poles and single-wall construction to cut grams, while lightweight freestanding tents trade a bit of weight for easier pitching. Several products marketed as ultralight in this pool are really lightweight backpacking tents rather than sub-2-pound shelters, so check the packed weight before buying.
