I just got back from 10 days in the High Sierra's using the Siltarp3 every night and I am sooo happy with it. Lightweight, waterproof and roomy enough to keep my claustrophobic partner happy. During bad weather I put my tail to the wind, sanded in the three staked out sides and hung and tied a piece of mosquito netting over the opening. Worked like a charm. This is one great piece of gear that stays in my core pack.
