Mountain Hardwear Flip 25/40 Sleeping Bag

There aren't too many multi temp bags out there, I only know of 3, which is sad because it really is an excellent concept, especially for those traveling through different climates.

I've used this through many a summer night, one awesome thing about the bag is that the non full length zipper side has roughly 24" worth of zipper so you can open it up and flip the top of the bag off yourself when it's warm. It also allows a shorter person to use the bag and make sure their feet are in the footbox during the winter.

It does pack a little big and thick but I'm not carrying this on my back.

The semi rectangular shape and design gives you just enough snugness for the cold while still offering the wiggleroom of a rectangular bag.

I've also used this bag in some serious winter conditions (read the answer to another customers question below) and was I not only comfy but I was HOT and had to open up the zippers on both side and push most of the bag off my chest.

If they only made another dual temp bag in either down or a lighter synthetic insulation, perhaps in say 0\25 degrees.....

My wife and I both bought Mountain Hardware Flip 25/40 bags and are well pleased. I do not like the feel of a mummy bag as I don't like anything on my head while I am sleeping. This bag is somewhat of a hybrid as it has drawstrings at the top of the bag that can be used to snug the bag up around your neck to prevent air loss without actually giving that closed in feeling. I also like the flip concept. The temperature was in the 45-55 degree range on the trip when we used the bags this April and my wife used the 25 degree side of her bag and I used the 45 degree side of mine.
These bags stuff easily into a 7 by 15 stuff sack. I think they would go into a somewhat smaller stuff sack without too much trouble.
