Help me choose a sleeping bag please

I had a Summerlite- great bag, great fit/finish- was simply too small for me, it's a rather tight cut- if your smaller (or maybe even medium-ish) probably will be fine, if you're a little larger than you'll likely find it tight.

One other bag to look at is the Marmot Helium, quality down and workmanship, but cut much more fully

The montbell is $294 at Prolitegear.com
If you are slim you can get a feathered friends Merlin on clearance from Prolitegear for $264. It is only a 58" girth bag, summerlite is 59"

Both will be warmer than the summerlite, which EN tested at 35F , the Merlin is likely 25-28F in reality with 12oz down, 23oz total.

They also have the Osprey on clearance for $279, its bigger and about 27 oz I think

I have a WM Megalite regular B/C it has more shoulder girth. I'm 5' 10" with a 42" chest and it fits me fine. I like it because I can easily wear insulated clothing in it and not feel confined and not squeeze the bag's insulation.

Also the Megalite is good as a quilt on hot nights when unzipped and spread over a mattress. I tuck the foot of my TR Prolite pad in the foot of the Megalite and the bag stays put all night. It's very comfortable that way – almost like sleeping at home.

I've been very happy with my summerlite down to 30F. If weight is a deciding factor though, mine comes in over spec at 21 oz, so not as big a difference there as you might think.

i have the ultralite… you cant get much better than WM
