Every ounce that we pack on months-long thru-hikes must be carefully considered, so instead of throwing a three-pound tent in our pack, we make the smart choice and opt for the 14-ounce MSR Thru-Hiker Mesh House 2. Its ultralight design protects from bugs when you go through the High Sierras on the PCT or the muggy Blue Ridge Mountains on the Appalachian trail. A versatile design allows it to be pitched under MSR's Hiker 70 or 100 Wing (sold separately) when you need protection from bugs and rain, and the non-freestanding design means you'll want to bring trekking poles for an easy setup. The Thru-Hiker comes with six MSR Needle stakes, so you can be sure the shelter's secured before you climb in for the night.
