[quote=Fishmonger]Deflation takes a while if you want to get it back into the rather tight stuff sack. [/quote]
I find this:
with Thermorest and others with foam, I release the valve, then immediately start rolling it up, pressing on it with my knees and weight to squeeze out all the air
different technique with the light weight ones (like NeoAir)- I find it better to release the valve, then lay down on it with it flat for a while until it stops hissing. Why? It lets so much air out of it that I can then fold with only a little hand squeezing, then easily put into the stuff bag . (I could have tried that with the Thermorest self-inflating but never did)
