I'm trying to figure out an adequate but minimal insulation option for late summer / high mountain hammock use. Temps probably won't drop under 50-55 degrees. Cool enough for ice ass, not cool enough for a normal under quilt. My hammock has a pad sleeve. I'm picturing something at least 26" wide, 72" long, but fairly thin .. maybe an inch or less? I'm trying to keep weight and bulk minimal .. this is for off-trail use in timbered areas.

What's out there?

T O M,

You've stumped the backpackers here ..

I've used this; also works on top of a inflatable pad in cold weather - INSULATION MARKETPLACE SmartSHIELD -3mm 48inx10ft ReflectiveINSULATION roll, Foam Core Radiant Barrier, ThermalINSULATION Shield - Engineered Foil https://a.co/d/87kcwYp

Scroll down,, 1/8'' & 1/4'' , might work for you.
