In house I have a Green Thermo wider longer Pad and a Rubber Blue waffled Pad from WM. I have never used a Pad and so far Speer universal UQ & TQ has done the job. Low temps about 38f +- without a sleeping bag. Which Pad? I plan a hang & fish North of Hwy 80 in Allegheny NF mid April. Right after the SS check arrives.. @ Beaver Meadows.
