Exped's Winterlite mats offer a high level of insulation and the comfort of a 9cm thick mat at a very low weight, the only compromise is one the shape - which is mummy rather than rectangular.

Exped says: SynMat WinterLite is designed to be the lightest 4-season sleeping mat on the planet.

Tapered design, 20 denier fabric, microfiber insulation and 9cm thickness create a balance of features that respect the most weight and bulk conscious winter campers. This mat also offers the warmth needed for cold sleepers in spring and summer conditions. It packs to an extremely small size and it's tapered profile fits into the smallest tents.

Exped's Synmat WinterLite mats blend thicker 9cm profile for comfort and warmth with a high level of synthetic insulation to achieve a high R-Value making it an ideal 3-4 season mat. Weight is reduced by adopting a mummy profile, for sure rectangular mats are easier to live with, but if you are going to compromise to shave weight then this may be a good area to do it, rather than sacrificing the comfort of a 9cm mat or the insulation on offer. A good choice if you want a mat that will allow you to encroach into winter but where weight is still pretty important.

We've tabled the various models of Exped mats below, so you can make a high level comparison. A few pointers though;

  • Synmats are filled with Synthetic insulation, whereas Downmats are filled with Down.
  • The numbers 5,7,9 refer to the thickness of the mat in cm - the thicker the mat the more comfortable it will be, especially for side sleepers.
  • Mats with UL (Ultralight), Lite etc in the title are designed to be lightweight and will therefore use lightweight face fabrics - the standard Downmat 7 and 9 use heavier, more robust fabrics.
