Geoff Connerwrote a review of Big Agnes Q-Core SLX Insulated Sleeping Pad on April 26, 2017
Familiarity: I've used it several times
I picked up the Q Core SLX for two reasons:
1. To compare the comfort of the offset Ibeam construction vs the vertical Ibeam construction on the Exped Synmat UL7 since it's the same weight.
2. Test the new valve system, which has to be better than BAs previous valves which weren't that great.
Initial impressions: I do think the Q-Core SLX's design is more comfortable and I don't slip of the pad like I did on the Synmat UL7. I find the valve system to be kind of funky to inflate, but adjusting pressure and deflating is easier than any other system out there. It's not as light as the NeoAir Xlite or Synmat Hyperlite, but the extra comfort is worth the 4 oz in my opinion.
Will test durability over the upcoming backpacking season, but I'm pretty impressed after a few uses. Will update!
