    I am a long time backpacker and a Boy Scout leader. This sleeping bag is a well made, full featured bag that really does its job! The weight is great! I have always recommended SlumberJack bags and they are a real value ! I really like the fact the draft tubes are large and well done, the zippers are sturdy, nice fleece lining in the hood..and they boys are WARM! All the features of a more expensive bag, including light weight, and for a great price! SlumberJack also stands by their products with good warranty service and customer service. I have kept coming back over the years and will continue to do so! THANK YOU! from Boy Scout Troop #3..we are warm, well rested and ready to hike!!

    Careful although the sleeping bag works just as promised the zippers are the cheapest in the world. Once unzipped the entire way, to air or dry bag, takes much time and effort to get back together.

    I am a long time packpacker, hiker, and camper and over the years I have seen a lot sleeping bags and I must say Slumberjack has really created a great sleeping bag, the Lone Pine 20 has every bell and wistle that you could possibly want in sleeping bag but at a way better price then some of the other companys out there. I am 5-7" and about 175 and this sleeeping bag fits very well with just enough wiggle room to roll around in the middle of the night, the flip over fleece lined hood is a really great idea it let's you really wrap the hood around your head and the fleece of course gives you a little extra wamrth, I would say if your looking for a light weight compressable sleeping bag that does what it's supposed to do then I would deffently give it try. Keep up the good work Slumberjack..
