I would recommend buying this product. It's extremely light, yet keeps you plenty warm. The straps fit around my Therm-a-rest Neoair allowing me to tighten the quilt to my pad to avoid drafts. The only issue is the snaps/buttons on the quilt. I don't know what they're for, but you have to be very delicate unsnapping them. I plucked one off the first trip I took it on. It was my own fault for being a brute, but unfortunate they're so easily broken.
