Does it lock you in place decently well in the night?
I cannot stand how bad I slide around on my Xtherm, granted I plan on switching to a ZenBivy setup to eliminate that issue entirely whether I switch pads or not.
I added a tube of silicone Seam Grip to my Xtherm and it definitely mitigated how much I slid around. Added 3-4 oz of weight but still worth it to me
