ALPS Mountaineering Razor
Here's what other sites are saying:
The Razor is a mummy version of the Alps Mountaineering Fleece Cover. It can be used year round - as an accessory or as a standalone bag. It is a great "accessory", even if you already have several bags. It can help add extra warmth on those extra cold nights. As a standalone bag, it can be used in warmer temperatures when you only need a very lightweight bag. With a bag that works, whether it is warm or cold, and with mummy or rectangle bags, you can't go wrong with this choice... a value that lasts all year long!
Use the ALPS Mountaineering Razor Sleeping Bag alone on warm-weather backpacking trips, or pair it with a liner to boost the warmth on cold nights.
Sleep in the ALPS Mountaineering Razor Fleece Sleeping Bag/Liner alone on a mild summer night or stuff it inside an expedition weight bag to add additional fleece warmth when freezing weather strikes. The lightweight Razor stuffs down to a size you can easily fit in your winter camping bag, cross country sled or in your car as an emergency insulation option. When fully unpacked, the mummy shape easily slides into another bag, and the full-length side zipper gives you the freedom to vent hot air or climb in and out of this liner without hassle.
