The opinion of Aventure Nordique

The Sea to Summit Pursuit Plus SI is a comfortable and warm 7.5cm thick self-inflating mattress.


This robust mattress is made from Bluesign approved 20D recycled fabric.


It's designed with Delta Core technology, which maximises the comfort and thickness of the mattress while minimising weight and bulk:


large horizontal and triangular inserts reduce weight and bulk without compromising on comfort and support.
PU foam is thicker at the top of each Delta Core insert for better insulation directly on the body.
The Pursuit Plus SI has a unique valve with a non-return valve (inflation/deflation). This allows rapid inflation and efficient deflation. The non-return valve prevents the mattress from reinflating during folding and can be used to manage pressure.


It comes with a carry bag with a side opening for easy storage. Repair kit included.

Points to remember

Comfort and warmth are maximised for touring in all climates.
