Most Mont-Bell sleeping bags are "on sale" (less than MSRP) at moontrail.com BUT, you also get "Bonus Points" on several bags that can equal $60+ in other free gear.
I got a Mont-Bell UL Spiral Down Hugger #3 for $229, but got 39 Bonus Points which got me a free Snow Peak Trek 700 pot, Ti Spork and 6 Vargo Ti stakes free!
I got my son a Sierra Design Nitro 30 bag for only $189! (They are out now, but if they get more they will be about $219, still $60 off)
They ship fast and have a great return policy. I actually returned the Spiral DH #3 and got a Super Stretch #2 (which had more bonus points, so I got more free stuff!).
No, I don't work for them, I own a high end audio cable company, check it out www.puresilversound.com.
