I've been looking at some Big Agnes sleeping bags and interested in adding one of their REM sleep pads. Seems like a great idea (the pad inserts into a sleeve in the base of the bag), but I was wondering if this would be a mistake because the sleeping bag sacrifices insulation on its base. Should I go for the "system," or just drop for standalone sleeping bag and sleeping pad? Brad Durango, Colorado

Drawbacks? Yeah, some. Mainly, these systems orient the bag in a single way, and tend to assume you want to sleep on your back with your face looking straight up. If you sleep on your side, the hood at the back of your head must turn with youwhich it does, a little. And there really isn't a huge weight savings. Big Agnes's 20-degree down-filled Zirkel ($279; www.bigagnes.com) weighs two pounds two ounces, which is pretty good. Feathered Friends' 20-degree Swallow ($320 with Nextec shell; www.featheredfriends.com) has down all the way around yet weighs an ounce less. Meanwhile, Big Agnes's self-inflating REM Air Core pad will run you $55, and add a relatively wispy 19 ounces to your load.
So it's a matter of taste. Big Agnes's stuff is practical, well-made, and well-pricedI never thought they'd make it when their stuff first came out four years ago, but here they are, doing great. Myself, I tend to prefer the separate pad and bag route. I just find it a little more comfortable. But that's just mepeople have been known to disagree...
