UL 60 Quilt…

I don't have any direct experience with the BPL quilts, but the 0.6" loft measurement sounds realistic. If my conversion is correct, the 68 g/square meter layer of Polarguard Delta weighs about 2 oz/square yard. By comparision, 2.5 oz/square yard Climashield XP provides 0.6" of loft (that number comes from Thru-Hiker.com).

I've used the cocoon 60 quilt a lot over the summer.

I use a bivi sack (the Vapr)
I wear all my clothes. (minimal)
I also use a cocoon 60 balaclava

For the rockies in the summer, it's fine! 40 degrees is easy. No tent, just a tarp. Yes, it;s thin. But heck, it's only – like 8 hours a night.

If nothing else, if you have one of these, you can always marry it with another sleeping bag for lotsa extra warmth.

Hi- I have one too. I might sleep a little colder than Mike but for me, it's good to 50 deg or to about 40 with a full Cocoon outfit.

It has a closed footbox that does not open.

Doug,

Will the new xp stuff include a regular sleeping bag?

See my review of the Pro 90 quilt; I assume the 60 to be much the same but thinner.

My initial experience with the bag is similar to Siegmund's review. I also have the Pro 90 like Siegmund.

I've only used it a little over a week and only as a inner bag. I don't think you could use it as an outer bag with any 30 degree bag without compressing the insulation (esp down). It just doesn't have a generous enough cut.

Seems like an ideal bag to be used in warm conditions down to about 45 or so (maybe 40 with a bivy). I'll save 11-12 oz compared to my 3 season bag. I'm hoping to get out in the next month or two and test this out. I'll probably also be using again as an inner bag to boost my 3 season bag (also the Montbell #3 like Siegmund) down to 20 degrees.

Hopefully I'll be able to post a more in-depth review after I've used in a couple different conditions.

I bought the 180 on close out. No experience with quilting (smile goes here)

Slept in my backyard last night, sub 40 but not freezing, (accuweather says 39)

Slept in my clothes and jacket with normal beanie on (baclava would be much better) Z lite foam pad

Very concerned about how thin the bag is. WOW.

I read the review on the 90 and all the points there are valid.

I was pretty suprized that I wasnt cold and slept hard until it started raining on me at 3am. (no bivy set up)

I do have my concerns that I would be cutting things too closely in a september alpine situation which is what I purchased the bag for. Married with a bivy, with all my clothes on, yeah… But there are NO comfort ounces carried here.

I have to admit I was pretty suprised by the performance with as cold as it was last night

180 grams per square meter is about 5.3 ounces per square yard.

My experience to date with an MYOG quilt and balaclava made using 6 ounce per square yard PL1 seem to be in line with Steve's. Wearing light socks, nylon pants and a light long sleeve polypro T shirt, on a 48" prolite 3 pad (sub-optimal) and a less than optimal setup to mate the quilt to the pad and a less than optimal neck closure I was very lightly chilled at 32F.

After improvements, testing will resume when morning temps warm back up to the 20's.
