Here's my first Aid kit. Weight is about 3oz
Band Aids -assorted
2' duct tape= multi-use (on trekking poles)
Also toss in Poison Oak wipes if that's an issue where I'm hiking.
Only thing I have that you don't is the tweezers, and compression wrap, which I figure doubles as guaze for a big cut/scrape. I also carry floss + needle for emergnecy gear repair that I suppose I could use to stitch myself up if I didn't pass out thinking about it first.
There's really only so much self-care that you can do out in the woods.
