Lavish space and low weight: These are not qualities you typically associate with four-season tents. Yet the 41.7-square-foot Convert 3 has both, as well as a modular vestibule system that let us cut nearly a pound for fast- and-light trips or add a vesti at each end for expeditions (it comes with a 17.1-square foot one; buy a second for $120). It’s a wind-shedding, three-pole, tunnel tent with a ridgepole that boosts headroom and adds rigidity. “It’s not Everest-worthy because of the large, unsupported sidewalls and vestibule,” says one tester. “But it held up fine to four nights on Rainier with sustained 25-mph winds. And it’s light enough that I’d carry it on summer backpacking trips.” The external pole system is fast and dry: The interior never gets exposed to precip during setup.
