I have been looking for a good down sleeping bag for a long time and have been very hesitant because of the price. I have had this one on my wishlist for over a year now and am so happy I finally decided to purchase it. I have a week long backpacking trip in the Porcupine Mountains coming up and wanted something that I know will keep me warm. I will update my review after the trip...My biggest concern was the size. After reading the dimensions I was nervous. I'm a athletic build 5'3" 135lbs, was going to get the short, but afraid of the dimensions! I now see after getting in the bag that the short would have been fine for me. The regular is a bit too long but I can throw the clothes for the next day in the end to get warm. (Short: 72" long, 26" wide at the shoulders, 21" wide at the hips, 11" wide at the toe box) (Regular: 78" long, 28" wide at the shoulders, 22" wide at the hips, 11" wide at the toe box)
Where my shoulders are 32" and hips are 28" so I was not sure how that was going to work out...I got in it and still had room to move about, I could have gotten the short and it would have worked.

Before purchasing the sleeping bag I got a nice email from the owner of the company touching base if I had any questions or concerns. Very nice touch, I love the fact that I'm helping out a fellow American small business owner.

The sleeping bag is lightweight, and in the comp. sack decent size. First full size photo of the sleeping bag is opened up right from the comp. sack. As I have been sitting here inspecting it, it is already fluffing itself up. I didn't shake it out or anything by the second full length photo. It inflated to roughly 4.5"-5". There are 2 pieces at the foot end for hanging the bag upside down. The drawstring on the hood and inside the bag are nice. They seem to be comparable to other high-end brands. There is a velcro piece that goes over the top part of the zipper at the head end. Its not the easiest to get undone if you are all bundled up inside with drawstrings closed, but perfectly doable. The zipper is double sided so you can unzip from the inside as well as from the foot end, if your feet get too toasty...I like that. I just wish that the end zipper had a little pull on it like the top one does...I'll just add one on for convenience.
The only thing that I can see so far that was from other reviews is that there are a couple threads loose along the zipper. You can see some in one of the photos. I think that they just didn't get trimmed, but won't effect the performance in any way. It is a "plastic" feeling material but there are no feathers poking out through the fabric yet. Its the same feel as any other down coat or vest I have so I'm not too worried.
They also attach a sticker that you can use to the tags. the "extras" are like a cherry on top.

I'm going to follow the instructions from the owner and take this on my adventure, when I get back I'll add an update on the performance and sleep quality!

I am really happy with this sleeping bag. It costs much less than major competitor brands, and supports small businesses!

I bough this bag to take on a recent trip to Zion national park and loved it. The weather got down to around 35 degrees and I slept it an t shirt and running shorts.

The weekend after I took it backpacking in Yosemite the weather where we camped was about 27-30 degrees at night. I slept fine, nice and warm.

The construction is good, nice heafty zippers and plush comfy fabric. It definitely has a bit of a plasic sort of feel to it, it's not brushed with any super soft lining, but it's comfortable none the less.

Warm light and comfortable, I have 2 other bags that I LOVE for summer camping and this was a great snag for my few "colder" trips I take every year.

I just hiked the Grand Canyon in March with a used REI 20 degree bag. First, the bag didn't compress much and it didn't fit in my backpack, which was a pain. Second, the temperature got down to 36 degrees and I couldn't feel my feet about halfway through the night. I realize I'm from Phoenix and not used to anything below 100 degrees, but this was ridiculous!

In planning for a 4 day Yosemite backpacking trip, I knew I'd need a warmer bag that packed smaller. The Hyke & Byke Down 15 degree bag seemed to fit the bill and the reviews were great. I have to say, I loved the bag! It was comfortable, packed smaller than the previous bag and fit in the bottom of my pack easily. Temps got down to 30 one night and I was perfectly comfortable. On warmer nights, I would unzip the bag and that worked fine. The zipper never stuck as some reviewers mentioned, and I didn't get feathers all over me as others had warned. So all in all, I am very happy with the bag.

Nice packable light and snall sleeping bag. Perfect to fit in your hiking bag.
Not sure about the 15 weather resistance. I have teated it around 32 degrees and seems to be the limit temperature.

I've used this bag at 30F up to 60F and was comfortable at both temps. Good quality and is easy to stow in its bag. Zipper runs along the entire side so you can open/close the bag as needed for ventilation. Also has a drawstring near the head opening so that you can close yourself up cocoon-like if you wanted to in cold temps. Great sleeping bag for the price.
