Hyke & Byke Quandary 15°F Cold Weather Mummy Hiking & Backpacking Sleeping Bag - Duck Down 650 FP 3 Season Sleeping Bags for Adults - Ultralight with Compression Stuff Sack

I have been putting off purchasing one of these bags. I finally got around to purchasing one, and overall I am going to say, this bag is very nice. This is the regular sized bag. I purchased one for me, and one for my son.Super light weight.Compresses down very smallVery comfortableNot for sure if this bag would keep me warm at 15 degrees, but, I probably will never test it at that temperature, as I do not winter camp. Usually I only camp starting mid spring into mid fall. So the lowest temps that I will be using this bag will probably be an occasional mid 30's. I do sleep cold, so that is why I purchased the 15 degree bag vs. a 30 degree bag.I have only used it once so far, and after a few outings, I will update the review if needed. The one time I used it, I slept good in it. Temps got down to 48 or 50, and I stayed warm in it. I am a side sleeper, and at one point I did wake up with my lower back and butt a little chilly, but that is because I was sleeping with my knees drawn up some, and had compressed the sleeping bag and created a cold spot. I had a top quilt with me, and once I threw that over me, I slept fine.Zipper functions great and the foot box was nice and warm.The fabric is somewhat slippery, but I had no problems staying on my sleeping mat.UPDATE: Tested this bag in temps that got down to 24F. Was using an inflatable pad and a small down throw from Sam's Club inside the sleeping bag. I did wear long johns as well. I stayed toasty warm and slept nicely! I do believe this is the best sleeping bag I have ever owned!The weight of this bag is 2.9 lbs.

I bought this for a 7-day trek in Philmont Scout Ranch. It performed spectacularly! It was warm enough for cold rainy nights and comfortable to lay on when the temps were in the 80s. It's not the smallest/lightest bag out there, but for the price it was light enough for me. I got the small/short size; I'm 5'2" with a slim build. It is roomy enough to have a little space to move. The zipper and cable work great to snuggle in. The cell phone pocket.... not so much - I think it's in an odd place. When lying supine, it put the phone right on my chest. I'd rather have it on the side, maybe by the zipper, but it's not a deal-breaker. Great bag; oh, and it's my family's second Hyke&Byke bag, as my son has the one that works on a hammock- he's had it a few years for Boy Scout trips and loves it!

Worked well for a 2 day ruck. Night temps were not too cold around 50F but quite windy around 25mph winds with stronger gusts. The insulation is great and didn't let the wind chill get to my body. I will say the compression sack it comes with is pretty awful it does an ok job if you have a lot of space to spare but if you're rucking/backpacking the more compressed down the better (it makes it smaller and far easier to organize things instead of just stuffing everything to make it fit). That being said a proper 12L compression sack is like 16 bucks and will pack this sleeping bag down about 2X smaller than the provided compression sack. I was a bit skeptical on how well this sleeping bag would compress down considering it is a mixed fill with down and a synthetic material, it seems the synthetics are always thicker and heavier to achieve the same warmth rating but this one packed down better than my friends REI 100% down filled sleeping bag (partly because of the compression sack i used *M-TAC 12L SIZE M*). The outer material is lightweight but pretty sturdy, i move a lot when i sleep and sometimes ended up off of the sleeping pad on the rocks or sticks but didn't tear or puncture.TLDR: it's a great sleeping bag but the compression sack it comes with sucks.

I was a little hesitant to buy this bag as I didn't know anything about the brand. My initial impression is that it's a good bag. It's late in the year for camping in my area, so the bag was tested on my back patio. It was 27F out and my patio is cement. The bag kept me perfectly comfortable (I get cold easily). I could feel some cold through the bag on my hip when lying on my side, but I believe that says more about my pad than the bag. I only wore a thin pair of pajama pants and a t-shirt and stayed comfortable. There was snow on the ground ~5 feet from me and my breath came out in huge clouds, so I would say the bag exceeded my expectations for warmth.It is a bit like sleeping in a large black garbage bag, but it's not as noisy as expected. The outside material seems very thin so I cannot speak to it's durability. I didn't notice any smells from the duck down as some have experienced. However, as others pointed out, the zipper is a little difficult and the reason I knocked off one star. For my use it's not a problem, but if you are going to be using the bag frequently keep that in mind. The bag stuffed easily back in its bag and the compression sack worked great. Bag is as advertised and fit nicely in my hiking pack. Overall, I am happy with the purchase.

When this bag arrived I was surprised at how small and light it is no bigger than an old pack of CD blanks. I followed the unpacking instructions and it fluffed up nicely. The zipper is very good and sturdy. I got into the bag and was surprised at the fit. I am 5'6" weighing about 200 pounds. The foot box is generous to keep my feet warm. The compression bag is of the same material and works well. The bag is water resistant. There are instructions on how to make it water proof. I have not taken it on a trip yet, but I do look forward to it. By the way, the company follows up with you to be sure you are satisfied and will be sure you have all of the proper care instructions to keep your bag in top shape.
