Hello! I'm looking for input on my gear list for a late March start (specifically my clothing system).

Some thoughts:
I've hiked in ~40 deg weather with this clothing system but not freezing rain/snow. Is it safe to hike in my sleeping clothes if it's super cold? Should I add a layer between the t-shirt and R1?

Should I add wind pants/rain pants instead of the DIY Kilt?

Do I need rain mittens and/or liner gloves? Can I just use my extra socks as gloves if things get bad?

The external battery is heavy and I'm not sure if I will need it. I will be using my phone for pictures, podcasts and music. It will stay in airplane mode probably 80% of the time.

Not sure if I need the tyvek. I'm not really worried about my tent, but I may want it to protect my pad in the shelters/cowboy camping.

Anywhere else I can save on weight? Any advice is super appreciated. Thanks!
