Summary: I was looking for a bag that would perform in the damp and could survive abuse stuffed into a dry bag and crushed in a boat all day. I bought this bag particularly to keep me warm in the northern wilds of British Columbia and his bag fit the bill nicely.
Summary: I just got back from using this at a Boy Scout Klondike Derby. I'm an assistant Scoutmaster. The site had over 30 inches of snow recently. The low temp got down to around 23-25 degrees. I stayed quite warm in this bag. I'm 6'3", so I got the long version.
Summary: Central Wisconsin has great opportunities for winter camping/back packing but a 0 degree bag is a must. My Fiancee' and I were looking for something to use in the -5 to 20 degree range that wouldn't break the bank. After some research we settled on the Trestles 0.
Summary: Bought this to go elk hunting in Idaho this year. Great bag at a great price. Most nights were in the 20's and I was plenty warm. Fairly light weight for carrying on backpack. Would recommend - well made and great value!
Summary: This bag is great for me because I pack it in a 90 liter Boundary Waters bag. Those who are watching weight and space may want to steer clear. I took a huge gamble bringing this bag into BWCA with temps of -30 F at night. I coupled this bag with a Thermolite liner and I survived.
Summary: This is my 2nd year with the Marmot Trestles. When frost forms on the bag, I have to ad more under layers. Comfortable in a tent when it is in the 20's, but not outside. I am 75 and do not sleep as warm as I did younger. Shopping for a new, lighter bag.
Excerpt: Purchased for 12 yearn old scout headed out on a cold weather camping trip. Temp dipped to 19F at night (chilly for mid November) and he says he was "toasty" all night. That's the only approval I needed!
