>>242652Klymet Inertia X-Lite, pic related, is very light weight! rolls to about the size of a banana (or can of Redbull).
I liked it so much I bought their Inertia-XL, a full-sized version, a great pad! Still very light @ 1.1# and rolls to about the size of a water bottle.
Am looking into a better insulated pad like the Big Agnes Q Core SL (about the same @ 1.1#).
