Lightweight Touring on a Singlespeed

^^^ sleeping mats, if you don't want to spend £40-80 on a decent inflatable (that packs down tiny and weighs 500g and makes sleeping out as comfy as being in a proper bed)

having bought and used a Thermarest mat (£67 quid off ebay), I can vouch for this and say that no matter where you are you will feel like you're sleeping on a proper comfy mattress. i've slept a fair few places on it in total comfort (draughty floors of houses, lumpy floor of a winnebago, camping etc).
