The Exped SynMat UL Winter is a high performance sleeping mat from the Swiss masters of techy stuff. It does exactly what it says on the box, it is suitable for winter conditions and is surprisingly light considering the warmth.The Winterlite mats are not just for winter, they work equally well all year round for cold sleepers. This longer and wider version (LW) is particularlysuited to taller and larger users or for those wanting the absolute maximum insulation and comfort in extreme conditions.
The 9cm deep air chambers are filled with 200g/m² Texpedloft Microfibre which provides warmth down to -20°C yet is easily compressed for a small pack size. The really clever bit is how Exped have laminated the filling to the top and bottom fabric of the mat so when it is inflated the filling is automatically pulled apart to achieve maximum loft which lasts for the life of the mat. Another really clever thing about this mat is that Exped have made the two side air chambers larger than the others, this creates a concave profile that acts to keep you centralised on the insulation and also acts to stop you rolling off the mat in the night...genius!
A honey-comb embossed slip resistant 20D polyester is used for the top of the mat and the base is made from standard 20D polyester, both fabrics have a TPU Polyether film laminate to prevent air loss and stop water ingress. The top fabric has also been coated with Exped's GripSkin coating, which, as you would expect, grips your skin to minimise the amount you slide around in the night.
Inflation is simple using the two way Flat Valve. This valve sits nice and flat against the face fabric so it is far less susceptible to damage.Also included is the superb Schnozzel Pumpbag to help you inflate the mat, not only is it a lot easier than blowing it up yourself but it will not introduce moisture into the mat that could freeze and dramatically reduce the mats performance.
Getting the right mat to suit your needs is far more important than the sleeping bag, you should be looking at the mat and sleeping combination to give you the temeprature rating you need for the least weight and pack size. Bear in mind that your sleeping bag is only as good as the mat it lies on, once you get in your sleeping bag you compress all the insulation that’s underneath you, rendering it practically useless. Therefore it is essential to have a good insulating mat to protect you from the cold ground. An efficient insulating mat will enable you to choose a lighter sleeping bag keeping your pack-size and weight to a minimum.
