Looking for a superlight tent that's great spring, summer, and fall, with enough spine for mild winter trips as well' Point your eyeballs at the Big Agnes Slater UL 3 Plus 3 Person 3 Season Tent, which, unlike most Big Agnes designs, features solid ripstop nylon walls with small mesh vents that offer a little more warmth, strength, and durability than mesh, without adding more than a few ounces of weight. Toss in a silicone and PU treated ripstop nylon fly with fully taped seams and expedition style coverage, and you have a tent that pushes the boundaries of a traditional three season shelter. To keep your gear safe from mild winter to summer, the Slater has two vestibules, one of which is virtually as large as the tent, and two nylon doors that seal out the elements all year long. Setup's as breezy as an afternoon ridgeline, thanks to a super simple hub pole design that features Featherlite DAC aluminum poles that offer stability without any excess weight, and the guylines and webbing are reflective to save you embarrassment, and misfortune, of tripping over your tent in the middle of the night. If you're looking to shave even more weight in the summer, pick up the Slater footprint and bring just the fly and footprint for a light and quick setup option. For three plus season camping, it's tough to make a better bet.
