MSR Hubba Hubba 2-Person Tent

The MSR Hubba Hubba is the tent that every other ultralight 2-person tent gets compared to. At 3 lbs 5 oz (with footprint), it's light enough for long backpacking trips while being roomy enough that you don't feel like a sardine. Two doors and two vestibules mean nobody climbs over anybody for midnight bathroom trips. The freestanding design pitches easily even on platforms or rocky ground. The cross-ventilation keeps condensation manageable. Durashield coating extends waterproofing life without re-treatment. The Easton Syclone poles flex rather than snap in wind. Packs to about the size of a large water bottle. It's not the cheapest ultralight tent, but the durability, livability, and reputation make it the safest bet for serious backpackers.
