When you don’t want to bring your whole sleeping bag quiver to cover the range of temperatures on your next trip, pull out the Mountain Hardwear Flip 25/40 Sleeping Bag. This double-sided, semi-rectangular bag features Thermic MX synthetic insulation that insulates even when wet and a top draw cord to hold in heat on chilly nights. The Flip’s dual design features variable insulation on the top and bottom that allows you to flip the bag depending on the conditions. Zip the Flip to another rectangular bag to make room for two, or zip it open for a cozy camp blanket.
Bottom Line: One bag, two ratings.
Talk shop with all the gear freaks out there: ask 'em questions, upload/browse photos, and give your 2¢.
I own quite a few of these bags but I just can't tell and
I own quite a few of these bags but I just can't tell and no where is it written which side the 40 degree side is and which side the 20 degree side is. I can't even tell any difference in the loft of each side. I still love this bag, just curious.

Duh....isn't kind of obvious? The lighter/thinner insulated side is the 40 degree side (keep that side up on warm nights). The thicker insulated side is the 25 degree rated side (keep THAT side up on cooler nights). There is an obvious difference.

The Red side is 25 degrees and the Black side is 40. I.E. The top is the 25 degree part.

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.....
I am using a exped synpad sleeping pad that is very insulated.
I am using a exped synpad sleeping pad that is very insulated. I am looking for a lightweight bag that can do three seasons. I assume this bag you just flip as one side has more insulation that the other. Has anyone experienced this bag in the field. I am guessing that I could experience temps in the 30-40 range at Philmont in summer. Does anyone have Philmont experience and would this bag be ok for July?

3 days up in the mountains of PA during November. It rained for 3 days straight and in the mornings there were 8" icycles hanging off my motorcycle. The overnight low was roughly 0 degrees.
I slept with the 40 degree side up (I think, is the red side up the 40 degree side?) on an exped synmat 9DLX inside a Walrus tent. I was just wearing a long sleeve t-shirt (it was cotton, I know I know)but I was wearing insulated pants and a beanie on my head, I was actually hot all those nights....

You are correct, you simply flip the bag over to get the insulation weight you want, I use a 4 season thermarest, in a REI 3 season dome. I have used in it in weather down to 10 and been perfectly content for 4 nights. In short I love the bag.

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.
Yes, it is machine washable, and is easy to wash. It does take time, though.
From Mountain Hardware's Care Instructions
Machine Wash:
Zip up all the zippers, attach all Velcro and turn the bag inside out. Wash in a front-loading machine with cold water on the gentle or delicate setting. We recommend that you use the minimum amount of cleaning agent [I never use more than 1/4 cup - less is more] and scrub the head and foot section before you wash the entire bag. Use at least two rinse cycles to get all the soap out of the garment [I just rewash the bag without soap].
* Down Bags: use a mild powder soap or special down soap (available at outdoor stores).
* Synthetic Bags: use a mild powder soap or special synthetic cleaning product.
Drying:
When moving your bag from the washer to the dryer, do so carefully by carrying it from the bottom. Tumble dry in a large commercial dryer on low heat. The dryer must be large enough for the bag to flop freely around. Drying will take several hours and your bag should be checked often to make sure it is not overheated.
* Down Bags: as the bag dries, look for clumps of wet down and gently shake the bag to redistribute the down. Sometimes the down in the draft tube will need some gentle massaging during this process.
* Synthetic Bags: as the bag dries, check for even distribution of fill material. Gently massage the bag if any bunching is detected.
No-Nos
* Do not use a top-loading washing machine (the agitator will destroy the baffles in the sleeping bag).
* Do not use liquid soap or detergent [never never never never]. Do not use strong soap or detergent.
* Do not use your home dryer (they have been known to melt holes in the fabric).
* Do not lift your bag from one end when wet (lift the entire bag all at once from underneath).
* Do not store in a stuff sack (use a larger storage sack which allows for air circulation).
* Do not dry in the sun (the UV will damage the nylon).
