The Sea to Summit Sentinel XP2 proves a larger footprint doesn't have to cost storm performance. The same 40D polycarbonate-coated nylon floor rated to 25,000mm and the same 50mph wind stability that define the Sentinel line carry over at 2-person scale, so two people get the identical weather protection a solo XP1 camper relies on. Twin vestibules add up to 19. 6ft^2, nearly double the XP1's per-person vestibule space, giving two people room to store packs and wet gear without crowding the sleeping area. A 42. 9in peak height and steep walls keep the shared interior livable through a long, wet stretch, and the same fly-first pitch and dry takedown protect the inner tent through setup in the rain. What Our Gearhead(R) Experts Are Saying:"We split gear between the two vestibules on a three-day wet-weather trip and never once had to climb over each other's boots to reach our packs. Wind hit the fly hard on night two and the pitch held tight instead of luffing the way a lighter shared tent usually does."
