The Western Mountaineering Antelope MF Sleeping Bag is a 3-season sleeping bag for hiking into the mountains. Rated down to 5°F, the bag is sewn with a weather resistant shell called MicroLite XP™. It's all about warmth and protection from the elements, since you never know what kind of weather you'll meet in the outdoors. A down filled collar and draft tube help prevent any leakage or drafts and at 2lbs, 7oz, it's still fairly light for the temperature rating. It's not about to protect you from bears, but it will certainly protect against the cold and resist weather and tent condensation.

Product Reviews
Rated 5 out of 5 by from Great sleeping bag This is obviously not a cheap sleeping bag but if it is in your budget it is well worth getting. It is super warm and comfortable. In fact, maybe a bit too warm on the first trip I took with it when it "only" dropped to just about freezing. The way the zipper works it was easy to "vent" to control the temperature. It packs down pretty small considering the 5 degree rating. As you would expect at this price-point, the quality is top notch.

Rated 5 out of 5 by from Warmest Winter Sleeping Bag I Ever Used! I tried out several other different winter sleeping bags and this one is the best! It is very warm and comfortable to sleep in because of the material it's made of. I slept out outside on top of the snow with my insulated air mattress and this sleeping bag. The temp. was 11° F/ -11.66° C and when I woke up the sleeping bag was covered with a heavy frost. There was no damp feeling inside the bag and I was warm the whole time. I'm very happy with this purchase it was a little pricey but well worth it.

Rated 5 out of 5 by from very warm Had this bad out once so far. Did not test the lower temp limits of the bag (had it to 20 degrees) and it was definitely toasty and seemed like it would be fine a fair amount colder (I vented it a little at that temp). Construction is excellent - I also have a feather friends 20 degree bag and the zipper, cord locks, and snap on the collar are all a fair amount more robust on the WM bag.

Rated 5 out of 5 by from I’m finally warm!! Great bag. Warm and light. Now I can extend backpacking season to those colder nights. great loft. Ordered the regular length. I’m 6 feet so it’s just right. Would highly recommend

Rated 5 out of 5 by from Lightest warmth you can get, with solid function WM bags are usually the lightest warmth you can get for the weight, and this bag is no exception. While it's sparse on features (don't expect an inner pocket for glasses/contacts/etc. for example), what is there works and works well. You can tell attention has been paid to important details - there's lightweight but effective plastic material near the zipper to prevent snags, and the cinching pulls near your face are full sized and easy to find, despite the concentration on low weight. I've used the bag only down to about 10 degrees Fahrenheit, but it felt plenty warm and I wouldn't hesitate to use it at its intended rating. I tend to run a bit warm, if that helps.

Rated 5 out of 5 by from Excellent bag, even without a pad. ( Packed in a hurry) This bag was the best that I've every used. Great with the zipper, no snags. It is ultra lite like the tent I used. It carries well.
Date published: 2015-06-14
Rated 5 out of 5 by from This bag rocks, seriously I'm typically a very cold sleeper, and have shivered for years in so called "0 degree" bags. Even though this is a 5 degree bag, I've never been cold in it! I've woken up with frosty eyelashes and been toasty everywhere else. Long story short, this is the best sleeping bag I've ever owned. Arguably, its the best piece of gear I've ever owned, my boyfriend agrees. He has the same bag and we zip ours together. (pro tip: if you plan to to this, one of you needs to get the left zip otherwise you will have to become a stomach sleeper- gross)

Rated 5 out of 5 by from Couldn't be better! The sleeping bag is very comfortable and warm. The lining is very soft to the skin. I first used in Yosemite Valley in the start of May 2013. Even when temperatures dropped and it started to rain I was warm and dry in the bag. Humidity did not penetrate the outer fabric.,,,,Nice with the big dust bag so you can store the sleeping bag without compressing, protected against dust etc.

I'm exactly 6'. I don't really want to jump to the 6' 6" bag unless I need to because of extra weight. Being right on the borderline is a 6' 0" bag going to be ok?

Asked by: Tyler
Hy Tyler, thanks for the question! That kind of depends on how you sleep, your typical position and how much you might happen to move around. Generally speaking though, I think you should be ok with the 6' model. I hope this helps!

I'm 5'7. could I fit the small? How durable is the water resistant finish?

Asked by: Brad
Hi Brad, good question! If I were you I would go for the 6 foot option, unless you have an aversion to left-zip bags. The weather resistance in this bag is actually integrated into the fabric construction, so it should be pretty resilient to wear. I hope this helps!
