Lightweight 3-season tent. If you've bugged out into the hills, shelter from the elements is THE most important factor. I chose this ultra-light (only 4lbs) 2-person tent. I've used this while on a 5-day hike before and even in high-winds, the low-profile helped keep it standing. Don't fall for those 50 dollar Walmart tents when your life depends on it. Bought this one for $160.
The Specialist Duo from Sea to Summit is the next step of evolution for two-person shelters. When every ounce counts, the Specialist Duo can be erected with natural anchors and a pair of trekking poles, or you can utilize the super-light 7075 alloy pegs
