MYOG Summer Quilt from old mummy bag

[Tyler Miller]

I know this isn't much information to work off of, but I have an old slumberjack 20* quilt that I used back in the day. It has to be at least 14 years old. It kept me warm as a teenager through multiple treks, including Philmont, so it's pretty well used.

About three years ago I used it in the low 30's and it seemed to be at the limit of comfort. So I thought it would work great re-purposed as a summer quilt. I have cut off the hood, un-stitched the zipper, and seperated the two layers (inner and outer). Each layer of outer fabric has a layer of insulation sewn in. So I really could make two quilts.

My question is this – what temperature range do you guys think I could take this down to? I realize this is very subjective and open to so many variables. Just hoping to get a rough idea so I don't take it out in the low 40's and freeze.

How many inches of loft does it have? Not an absolute indicator, but a good place to start when figuring warmth out.

For reference… My MYOG 5.0 APEX (~1.25" loft) quilt keeps me super toasty down into the 30s wearing just boxers and a lightweight wool shirt. That's using a 4.1R pad and in a BA Fly Creek ul2 tent shared with my girlfriend.

What pad/shelter, sleeping partner, etc will also influence your warmth.

If you got a yard, try it out outside on a chilly night.

I'll measure it when I get home. I would think it's loft is ~1/2" per layer. I have a 20* EE quilt that I'll use for most nights, but this quilt would be for warm summer nights.

I have an Exped UL 7 (R value 2.8) and I'll either be using this in a Nemo Meta 1P, or a bivy/tarp combo.
