SIM Lite UL 3.8 Long Wide

The ultralight versions of our SIM Lite mats feature the same easy to use Exped flat valve and lightweight foam core technology and prove that self-inflating mats can be lightweight and compact.

Smart FlatValve technology: Exped was the first manufacturer to incorporate durable and easy to use flat valves in their self-inflating mats. Each mat has an inflation and separate deflation valve. Both valves have a one-way flap making inflation and deflation quick and easy.

The included stuff sack is wide enough for easy packing and can be used as a pillowcase when stuffed with clothing etc.
