UL Pro 90 Quilt limits?

Hello,
I would think your system would be good down into the 20's without too much concern. You would probably just want to make sure to pitch your shelter low to deflect any breezes. I use a Pro 90 as well and with the BMW Pro 60 clava, Pata Micropuff vest, ibex base and a pata houdini top and bottom I stayed comfortable down to 38 degree's in the Whites of New Hampshire last Fall.

you may want to look at the MLD offerings too.

I'd recommend a closer look at the MLD quilt too. During and after the purchase you'll have a good resource in Ron. Take a look at his temp ratings. They're amusing but I think fairly "accurate" and, at the least, informational.

BTW. With your setup, I'm going to suggest that you'll sleep "cool", but not wake-up cold, down to 30F, maybe high 20's. Keeping in mind this is all relational to your physiology and a variety of unknown circumstances.

good luck,

Hi Mitchell! I use a similar system for early Spring snow camping. Last spring I tried out a MB thermal sheet, which probably would be similar to a quilt, paired with a MB down inner jacket over a Smartwool base layer and a fleece pullover. Add an Equinox bivy and a MB monoframe diamond tent, and I was comfortable down to the mid 20s. A bigger concern, however, was ground insulation; the GG nightlight worked well as long as I stayed on it. If I happened to roll off, the cold seeping through immediately woke me up. The GL Jam under my legs sort of worked, but every now and then I could feel some cold spots. Given that, your system should work adequately. Happy trails!

Thanks for the feedback. I've also got the Montbell Alpine Down Jacket which is extremely warm, but I think the BPL quilt will compress the down too much to make it useful.

As for sleeping pads I have 2 options. I have an insulated Big Agnes pad which is great on snow and incredibly comfortable, but weighs 26 ounces. The other option is my BMW torso pad + my pared down thermarest Z-lite (17 total ounces) with my pack under my feet. I usually lean towards the second option and have found it to be quite suitable even on snow.

I'm always looking for new gear so if anyone feels there's a quilt that performs significantly better than the BPL quilt and does so at a similar weight I would be very interested.
