I bought 3 of these, one for myself and one for each of my boys, who are starting in Boy Scouts. The quality seemed great on all three and they arrived promptly in excellent condition. The workmanship and details seems first rate. After camping the weekend in an adirondak (open air cabin), at around freezing temperatures, my elder boy reported that it was plenty warm enough and compared favorably to a -30 down bag he'd been borrowing despite being half the weight and size. The company specifies that these are lightweight bags that are aggressively labled, so if you don't know how to stay warm/don't have the other necessary equipment the temperature rating is probably far lower than you will want to use them comfortably. A tent would have been far warmer than the cabin because of the open airflow, and he was using a medium weight pad and wore his base layer to sleep in. These compress to around the advertised size and stuff easily. The stuff sacks are good and a nice bonus for the price. If you're not worried about weight or size, these may not be for you. But if you plan on packing sleeping bags around, I don't know if you can find anything comparable for around this price. I've done a fair bit of mountaineering and mountain climbing and I have owned nicer bags, but not for less than three or four times this price.
