One of the issues I've had with my limited amount of backpacking is abrasive contact from different packs and the choice of shirt material. I've recently fixed the pack sizing issue I had (M/L sized for my torso, was bobbing around, so I got a different S/M size).

I've had to stick to cotton (t-shirts) because they provide a level of softness when compressed against the skin with a backpack hip belt and the lower back for hours, but if you're hot and sweaty, they're drenched afterwards and take a long time to dry as is the wont of normal cotton t-shirts.

I tried wearing a fairly soft feeling wicking sports shirt with my pack and immediately felt the abrasiveness under my hip belt on my skin even with anti-blister ointment without even leaving my apartment. No thanks.

I see a fair amount of folk wearing those ranger-style sleeved button up shirts. What are these made out of?

Does anyone else have this abrasiveness problem? I feel likle I'm the only one! I'm planning a thru-hike in 2 years and want to find the longest endurable solution for my delicate hip skin haha.

My new Osprey Atmos 65L pack fits my body type a lot better and stays put without much movement when hiking, but it has the wicking mesh on the contact, so I'm also wary of that pressing on my skin for days and days. Maybe I can attach a light layer of softening fabric to it or something.
