THE SELL: Big-time four-season protection at a reasonable weight. THE TEST: The two-person Alti Storm didn’t flinch in the Grand Canyon; its four crossing ridgepoles weathered 50-mph downcanyon gusts, and the full-length fly and nylon canopy created a sandstorm-proof bunker. The pole sleeves (rather than clips) add a bit of weight and setup hassle, but they also significantly beef up the Alti’s structural integrity. Two good-size vestibules swallow bulky winter gear, while the near-vertical sidewalls make it feel bigger than it is. Large vents help keep condensation to a minimum, and when staked out taut, the Alti sheds snow like an angry yeti. The roll-up stuffsack is cool but weighs almost a pound:leave it at home if you’re going backpacking. THE VERDICT: Bring on the blizzard! 8.8 lbs.
