The HyperSleep Winter is a great choice for lightweight backpacking with increased temperature rating so it can be used across the 4 seasons. There is very little can go wrong with this durable sleeping mat. Simple, effective and versatile it can be used to further beef up other mats.  

Exped says:

The super-lightweight virtually indestructible purist’s mat for 4 season use.

This multi-use closed cell foam mat works well by itself while offering a minimal comfort level - or as a robust undermat to any other contoured Exped mat like SynMat Hyperlite.

Made of Evazote, an environmentally sound closed cell EVA-foam (Ethyl Vinyl Acetat) which is optimised for expedition use. Acclaimed for extreme durability and is not rendered useless by thorns, debris nor your crampons. Multi-purpose:  Works as sleeping mat, flotation aid or cut it up to make insoles for your shoes. Dark color for quick drying of condensation. Ingenious contour shape for optimal layout in narrow spaces. Manufactured in Europe.

Exped's HyperSleep Winter Closed Cell Foam Mat has a good temperature rating for such a simple design. This type of map is all about simplicity and there is very little can go wrong with it. The closed cell foam construction keeps the weight low even for a 4 season rating although it's not the most comfortable.

Other mats may provide more warmth or more comfort but this will come at a cost with the weight and the price increasing quickly. 

This mat is quite large but due to the nature of the foam it is really easily cut to the shape you need. It is extremely durable and can easily withstand serious punishment from any surface you lay it on and kit that it might come into contact with.
