Our verdict
At 1474 g (3 lb 4 oz), this freestanding three-person, three-season tent delivers impressive livability relative to its weight. Its high-volume DAC pole architecture creates steep sidewalls and spacious interior volume, complemented by two doors and two vestibules. Owners consistently praise the roominess for two hikers plus gear. The main caveat from long-term reviewers is that the thin ultralight floor fabric rewards careful campsite selection, making a footprint a smart addition. The plain tradeoff is material thickness for weight savings. It suits two backpackers seeking extra space on multi-day mountain treks.
