The Big Agnes Q Core SLX Sleeping Pad is a superlight sleeping pad for 3 season backpacking. Nice and light when you stuff it in your pack and incredibly cushy when it's time to lay down for sleep. Sleeping on the ground is a whole new ball game when it comes to the quilted top with offset I-Beams, providing support and cushion. When it comes to colder nights in camp, the Insulation and heat reflective Technology can't be seen, but they can certainly be felt and appreciated. You'll know because instead of shivering on the cold ground, you'll be snoozing like a baby.
