From the manufacturer

Built For Life
Heavy duty design elements include soft poly rip-stop shell fabric, large #10 dual slider zippers, hydrophobic synthetic high loft fill, and a tough compression tote.
3D Gusseted Design
Air core fill reinforced sidewall keeps bag tall providing room for large feet and makes rolling over easy for a bigger person in the tapered mummy shape.
Internal pocket between chest and hood baffles to keep precious items hidden while you are away or asleep. Be close to your passport, wallet, jewelry, or mobile alarm clock.
Technical Highlight : Synthetic Fill
Coretech Bags utilize fully synthetic fill material selected based on four factors:
Compression To Loft Ratio: Silicon air core hollow fiber quickly restores to maximum loft from a highly compressed state.
Thermal Performance: Lightweight high loft fiber creates a wide buffer zone to trap heat, keeping the occupant warm in the tent and light on the trail.
Hydrophobic Profile: Synthetic material that resists bonding to organic molecules so it dries out quickly to minimize odor and maximize trail time.
Ecological Responsibility: Coretech Bags are Buy It For Life products - built to withstand the test of time. Rugged synthetic fill keeps feathers on birds, where they belong.

Now on to the company:
When repacking the bag in the compression sack, I found that it had two small vertical slices in the compression sack. I emailed the company directly to see if I could exchanged just the compression sack on a Sunday evening. I received a reply email in under twenty minutes from an excellent customer service rep Doug. He apologized for the problem and sent me out a replacement bag (yes full bag with a new sack). Apparently I had an older type of compression sack that was made by a manufacturer that they do not use anymore. So if you have the same problem, just email the company directly.
I also got a duffle from the company that is of incredibly high quality. This company is great and Although I do not write a lot of reviews, companies like this that go above and beyond really do deserve our business. I will absolutely buy from them again.
EDIT: I sent an e-mail to NorthStar, and received an e-mail just a few moments after, but it went to my junk inbox. The representative, Doug, took the time to follow up again so that I received the e-mail and offered to replace my broken bag at no cost. This is some of the best customer service I have received from any company and increased my rating. I will provide an update and pictures as well once the new bag is delivered.
EDIT 2: So I wanted to update this review again. The customer service I received was stellar. I received the new bag only a couple of days after contact, and Doug followed up the same day that I got it. I have not had a chance to use the bag yet or thoroughly test out the zipper, but it does seem to be of a stronger quality and the institching it a little more robust. I do feel confident that I won't have the same problem with this bag as the previous one.
My wife gets really cold almost no matter what! We were going backpacking in Desolation Wilderness. We watched the weather reports, and expected a 25-35 degree night. It ended up dropping below 20. I never get cold, I've had the same bag for years and I'm always on the warm side. This night was different. I was freezing. My wife didn't even close the drawstring on this bag, and she stayed plenty warm. Envious, but thrilled. My biggest worry going into this was if she would be warm enough, and this bag gave me peace of mind on that.
Unfortunately, it is big and bulky. It wouldn't fit in her or my backpack, so I had to strap it down to the top of my pack where the bedroll normally goes. We made it work. I carried the tent at the bottom of my pack, and her sleeping bag at the top, and she carried both bedrolls one top, one bottom.
You can see the bag strapped down to the top of my backpack in the picture. So, this bag... worked... but will probably be a car-camping backpack for us.
I am 5'10" and it is more than long enough for my body. I would say there is about another 5 or 6 inches of space in length. The foot box is quite roomy so it allows for movement while all bundled up. The zipper parts are all heavy duty with a large zipper "track" so it doesn't split open or get easily caught on the sleeping bag material like smaller zippers often do. The hood portion of the bag doesn't seal perfectly around the face, but here in southern California, it doesn't really get lower than 40 F unless you're in the mountains, so that's not a deal breaker. The draw strings to tighten the hood and area that goes around your neck/shoulders are easy to reach and use. The material seems to be a slightly heavier material than a lot of cheaper bags or backpacking bags. Stuffing the bag into the stuff sack that it comes with is very easy, but it doesn't compress down to the size that you would want for backpacking. Additionally, it's a bit heavy so I'm not sure you'd want to use this bag for hiking where you're trying to cut weight. Been using this bag for about a year on some camping trips where the temps got down to the low 40s F and the bag was very warm and cozy.
