I weight around 95 kg, so I was not too keen to sleep on 1.5 or 3 cm thick sleeping pads. I was searching for something thicker and more comfortable, yet lightweight, compact and easy to pack. I choose Therm-a-Rest NeoAir All-Season.
I recently start camping. I still have very limited experience with camping and ways to carry camping gear on my bike. This is how I set the bike for camping - noob setup and more mature setups following.
