Pursuit Self-Inflating Sleeping Pad

Solution dyeing is a process where dye is added to the liquid polymer before the fibre is extruded. The benefit of this technology is that energy and water use as well as C0? emissions are significantly reduced.

In solution dyeing, the colour runs throughout the yarn, not just on the surface as it would with conventional dyeing. This is easy to imagine if you think of the cross section of a carrot (colour throughout) compared to a radish (colour only on the exterior).

Solution-dyed colours may not be quite as intense, but they also do not fade like conventionally-dyed materials.

Bluesign is a system run by an independent, Swiss-based third-party group that monitors every step in a supply chain to ensure the use of the most benign materials.

This approval states that the product's production creates the fewest emissions and least pollution, holds high standards for humane conditions for workers and material safety standards for consumers.

Fabrics or materials used in these products are certified as recycled according to the Recycled Claim Standard. RCS is an international, voluntary standard that uses the ISO definition for 'recycled'. It sets criteria for third-party certification of recycled input and ensures responsibility throughout the supply chain.

Sea to Summit considers environmental impact in its choice of materials, and recycled materials are chosen only when they meet appropriate performance and durability levels.

This Sea to Summit innovation removes 40% of the foam in a self-inflating mat, leaving Delta-shaped 'cores'. This saves weight and reduces packed volume while creating foam-supported, air-filled channels that significantly enhance your comfort. Lighter, more packable, more comfortable: a win-win-win.

The Sea to Summit XPEL Valve was the first valve developed specifically for self-inflating sleeping mats. It integrates a one-way inflate port, a deflate port and a fine-tune button into a single, low-profile unit. The genius of the XPEL valve is that to deflate the sleeping mat, the valve is flipped over.

This turns the one-way inflate valve into a one-way deflate valve - preventing the mat from drawing itself full of air as it is rolled up.

The XPEL valve fits the nozzle of an Airstream pump (sold separately) if you want to 'top up' your self-inflating mat.

To ensure that you will be warm when you sleep (especially when the ground is colder), it is essential to know how well your sleeping mat resists heat loss into the ground. This resistance is known as an R-Value. A laboratory-tested R-Value is the only way to measure resistance to heat loss

Sea to Summit has always provided independent lab-tested R-Values for its sleeping mats. Since January 2020 we have used the industry standard ASTM F3340 test to provide R-Values for our mats.

There are several other factors which will determine how well a sleeping mat will insulate, but the standardized ASTM R-Value test means you can compare resistance to heat loss in sleeping mats across different brands
