Big Agnes Cross Mountain Sleeping Bag: 40 Degree Synthetic

My wife and I have been using non-zipping ultra light down bags for summer backpacking. They were great from a weight perspective, but restrictive of movement, often too warm, and didn't zip together. The Big Agnes bags solved all of those issues with only a small weight penalty. Although we had avoided getting the down bags wet, we often do overnight canoing where there is always the possibility of wet gear. The Polargard Delta would also be a big plus in that situation. Several other benefits are icing on the cake... the Cross Mountain is large enough and has interior attachments that allow it to be used as an outer bag with our down bags in colder weather, and the bottom sleeve for the mattress is an awesome design feature as I was always sliding off. (Note: This bag is intended to be used with a mattress or pad as there is no bottom insulation)

OK, as much as I wanted to give BA a 5 rating, I can't based on use with a cot. I was camping in Eagle Cave, WI with the scouts...52 degrees and a very muddy floor...thus the reason for the cot. First night I got cold and had to slip on some extra clothes...not a big deal, but I was hoping the 40 degree bag would keep me warm at 50 degrees, even off the ground.

I love this bag! I needed a warm weather bag, my -40 bag sucks in anything but cold weather, and the Big Agnes Cross Mountain is perfect! Their system of sliding your pad into it's own little pouch is genius. I'm a burly guy, and mummy bags and I have never gotten along. But this bag's plenty roomy, and with the pad attached, you NEVER slip off it. Genius. Top notch bag!

I pair this bag with a regular size therm-a-rest. Talk about a winning combination! I stay nice a toasty even with frost on the ground! I pack my pad separate from the bag, which allows the bag to compress into a small size Granite Gear Round Rock Solid Compression Sack. I love this bag!

I took this bag on a long motorcycle trip through the Rockies this summer and it was awesome. The whole concept of slipping the pad into the bag is brilliant. I liked everything about it. It was easy to set up and pack. I don't like mummy bags per se, but this is like an oversized one so I can move around a bit. Add the Big Agnes pad, and you won't even feel the ground when you sleep! I wish the zipper went further down the side, but I slept so well I didn't notice.

I like this bag a lot. I was reluctant to try the Big Agnes style of sleep, not insulation on the bottom and all. Talk about thinking outside the box. I was already sold on the Big Agnes Insulated aircore pad. I guess the bag was naturally the next step. I was concerned about the pad being attached to the bag because I thought side sleeping would be difficult. The bag is cut to allow side sleeping. Also another thing is this is very roomy. Lots of wiggle space. Great design. Great constrution. Great Bag.
