  • Arctic campout...warm!
Color: Black Size: Long
This is fantastic-did a winter camp in NM in Feb...got to 8 degrees f (really) and this bag kept me warm. I did have a liner in it with all my clothes on, but it worked well...too warm above about 50 though-you will sweat. I'll take it to CO this summer for a Maroon Bells hike above 12,5. It's light enough and warm enough. ... show more

  • Excellent Bag for the Price
Color: Blue Size: Long
Quick Review: Huge Fan of this Bag. For the price it is outstanding, would recommend a down wash after purchase to make it a bit more waterproof. Full Review: I love backpacking in the summer, and was looking to try to get into more winter camping/backpacking. I purchased this for winter camping in near zero or below Zero temps(Duluth, MN). I did my first test on a three day backing trip in Northern Minnesota along the Superior Hiking Trail, overnight temp the first night was between +4 and -2 Fahrenheit, second night was between 0 and -8 Fahrenheit. For sleeping I was using the following gear: Outdoor Research Alpine Bivy - Tent Hyke & Byke 0 Degree Down Bag Alps Mountaineering MicroFiber Sleeping Bag Liner Therm-a-Rest Z Lite Sleeping Pad - Closed Cell Base (R 2.6) REI Cirrus Insulated Air Pad - Inflatable Pad Between Base Pad and Bag (R 2.6) I knew it was going to be getting below Zero both nights, so I was also wearing some R4 long underwear, and wool socks inside the bag. I was also using the Bag liner to add some extra warmth. Overall, the bag performed beautifully! I was quite warm the first night, and actually didn't full zip the bag inside the Bivy. The second night was much windier and a bit colder, so I had the bag fully zipped and the hood cinched up tight(great feature of the bag BTW). Both nights I was comfortable enough to sleep through the night without any issues. Being inside a Bivy, there was a LOT of condensation(ice) in the morning, and the outside of the bag did get a little bit wet, but it dried well under little bit of sun curing the day. I am definitely going to do a down wash treatment on the bag to make a bit more waterproof in the future, though this was not enough of an issue to deter me from using it. If going right to that zero mark and below zero at all, I would definitely recommend a bag liner to add some extra warmth. I slept outside with this in about +5 degree weather(with no liner/long underwear), and was comfortable enough to sleep, but definitely missed the extra liner warmth when I woke up. I would not recommend going to far below zero for safety unless you are really confident in what you are doing. I did have some issues compressing the bag into the Stuff Sac provided, and was able to do it, but it was quite difficult to get it packed all the way in. The second night I used a Sea-to-Summit Compression Sac and it was much easier, so you may want to consider a different stuff sac than the one provided. The sea-to-summit sac was longer and made it easier to pack everything down, and with the compression straps I could get it to the same size as the included bag. Overall: I loved the bag, and for the price point it cannot be beat. I will definitely be looking at more Hyke & Byke bags in the future. ... show more

  • One of the warmest bags I've used
Color: Black Size: Regular
This bag is by far one of the warmest bags I've ever purchased for backpacking. It has a few drawbacks, but for a TRUE 0F bag it's spot on. Here's what I've done to test it so far. First, I took a backpacking trip in early March (Highs: 40F, Lows: 20F) around Greenleaf State Park in Braggs, OK. It's a 28 mile loop on some rough terrain. It was overcast the entire time, and a light mist seemed to be always falling. None the less, we pushed on and camped the first night within a stones throw of the lake. In hindsight, we should of pushed away from the lake a bit more due to the wind. Within an hour of sunset, the temperature plummeted. We had setup our tents and I had laid out my sleeping bag in my tent to allow it time to fluff up and expand. One thing to note: This bag REALLY puffs up once it's out of the compression sack. Crazy amounts of loft. OK - so after standing by the fire for a few hours the 12 mile day took it's toll and I fumbled off to my tent to try and get some sleep. Normally, I would be crawling into my Sea to Summit Spark II 35F bag, which only has a 1/4 zip (and is a huge pain to get into), and was pleasantly surprised to find that my bag had a full length zipper that would open from the top or bottom. I didn't realize how important this was until later. I crawled in and immediately found the texture of the fabric to be a bit tacky to the touch. I figured it was my cold skin, so I slid down into the bag. At first, it felt like sliding into an ice sickle. After about 30 seconds though, the bag started to warm up and the inner lining of the bag felt much better. Then, almost all of a sudden, I was WAY too hot. I don't mean just a little "let me open the top a little" kind of hot, I mean I almost started sweating within 3-4 minutes of getting into the bag. Holy cow! This is by far the warmest bag I've ever been in. Most of my other bags are 45F down to 35F with very little options to regulate heat other than sticking an arm out or unzipping from the top. Luckily, this bag had a foot zipper that I was able to unzip about 2-3 inches and that regulated the heat perfectly. The next two nights went the same way and I'm hooked. The biggest issue I have is getting out of the bag on cold mornings. I just don't want to. Ha! A+ bag! Highly reccomend. It's a bit on the heavy side, but for the price you can't beat this bag anywhere. ... show more
