Bringing this thread back up to the top. My Q-core SL Regular size came in today. I inflated it and it'll fit me perfect. I'm 6'0" 165 lbs (but I'm wiry! ha) and I have a little bit of length to spare but not much on width. I didn't throw a tape measure on it when inflated just wanted to see how I'd sleep. I can tell you that this pad is COMFY! Can't wait to sleep on it...
NOW here's the interesting part... on the scale that I use for shipping orders, the pad only comes in at 18.4 oz... Only .4 oz off the advertised weight. Not sure if they have started doing anything different but I trust my scale and it keeps hitting 1 lb 2.4 oz. With the stuff sack it hits 1 lb 3.3 oz... Either way I'm happy provided it's durable! This pad cut off about 1.25 lbs off over my Thermarest Expedition pad, combined with my SO Draft Dodger quilt at 24 oz and my Borah Gear Bivy I think I'll be sleeping better than ever in the mountains this year...
