Anyone tried the Exped SynMat HL winter or Exped Downmat HL winter pads? The SynMat is the same weight and R rating as the Thermarest. The Downmat only 1.9 oz heavier with a crazy 7+ R rating. I hate how noisy the Thermarest NeoAir is personally and quit using mine simply for that reason.
Downmat UL Winter here. Love the thing...
