Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on the Undetermined

Sea to Summit Camp SI Sleeping Mat - Regular

Season : AW21

Brand : Sea To Summit

Code : 5066603

The Sea to Summit Camp SI Sleeping Mat is ideal for campers who want a self-inflating mat at more affordable price point. The Camp SI mat is features a 1.5” thickness foam mattress that utilises Sea to Summits Delta Core-V™ vertical coring to remove unnecessary weight and minimise packed size.

A 75-Denier polyester top and bottom fabric offers excellent wear and durability. With an R-Value 4 insulation rating this mat series offers 3-season warmth and comfort. The multi-functional, high flow valve allows easy insulation as well as one-way deflation which makes rolling the mat up much easier. This valve also prevents the mat from filling itself back up with air when you roll it up. The core of the sleeping mat will give you the insulation you need while maintaining a low weight.

  • Utilises Delta Core™ technology, which keeps body contact areas warmer while still offering great support and packability
  • Multi-function, patent-pending multi-function valve twists over to allow the mat to be rolled tightly without fighting re-inflation as you go
  • At 1.5 inches thick and an equivalent R-Value of 4, the Camp Mat delivers a great weight to warmth ratio for minimalist hikers
