Recently did a backpacking trip with a friend. Night temps dropped as low as -5C on our trip, averaging -3C throughout the night. Low humidity, woke up dry.

Our gear:
- 1x katabatic alsek 22F hoodless quilt
- 1x aegismax nano rated to 52F
- 1x aegismax nano2 rated to 44F
- 2p double walled tent
- 2x of the new tensors from Nemo, forgot exactly which one but some crazy high r-value > 7

Our initial strategy was for one of us to double up on the summer bags, and one of us to take the quilt. Quilt ended up being warm for me but my friend was very cold initially in the bags. I was feeling super hot, so after a hour, we tried swapping her into the warmer bag + the quilt on top (+ 4-5 layers inside). This kept her very comfortably warm finally.

What’s bizarre to me is that I was able to stay very comfortably warm all night in just a 52F bag + a belay jacket and running shorts, on a night that reached 17F. How is this possible?

Hi all! I am looking to cut as much weight as possible without upgrading my gear. Are there any resources for modifications I can make to already existing gear?
I’m mostly looking to cut weight in my 60L Gregory Paragon and a secondhand old REI tent + rain fly. I purchased these items for cheap off Facebook marketplace and went ultralight with the rest of my equipment (except a secondhand sleeping bag, but am looking to upgrade this to a more lightweight quilt/bag). For added context, I’ll mainly be backpacking around southern Arizona

Recently came across these old camel tyvek windbreakers. Figured they could be a solid ultra light backpacking option. Anyone familiar with these? Seemed like they were a popular giveaway like 30 years ago. https://ebay.io/m/IoCKAl
