A good nights sleep is essential when racing a multi-day adventure if out fastpacking. Without sleep, our ability to recover is compromised and eventually, sleep deprivation will impact on performance, mental strength and even one’s appetite.

Carrying a sleeping mat is essential, however, the weight of the mat is crucial. In most scenarios, we want the lightest possible that is suitable for the conditions that we are running and also provides excellent comfort.

There are many options available on the market and recently I have been testing the Sea To Summit Ultra Light Mat (extra small) which has impressed me in several key areas:

Easy to inflate and default.
Small pack size.
Very lightweight.
Extremely comfortable.
Durable.

Finding a sleeping mat that provides this level of comfort in such a small pack size and weight has been a revelation. I was initially concerned that an extra small mat would be too small… Not the case, this mat has exceeded my expectations.

Under 300g in weight made with 400 TPU Nylon, the mat is durable and hardy to all conditions. The 132 Air Sprung Cells react as one would hope to body weight and provide a supremely comfortable night. In simple terms, the cells don not flatten out under hipbones or shoulders.The addition of a stuff sack and an Air Stream is a nice touch but comes with an additional weight penalty of 40-45g.
