Exped Flex 3R M

A closed-cell foam pad is the most durable type of sleeping pad: even if you jab it against a tree branch or a nail, its insulating ability is practically unaffected.

The Exped Flex 3R is the thickest closed-cell foam pad on the market on its release date (autumn 2026), and the manufacturer states a lowest operating temperature of -5°C. Winter campers often use a pad like this beneath an insulated air mat, not only for extra insulation but also to protect the air pad from punctures.

By folding this concertina-style pad in different ways, you can use it as a super-warm sitting pad, and when packing there are more options than just the flat, even-thickness form: the pad is easy to strap onto a backpack or a bike rack in several shapes.
