I use Troy Lee XC Gloves as I find them light and airy, and I’d sway towards the thinner no padded type if you are suffering from blisters, as others have said you will create hot spots and when they get sweaty the gloves will give you shit.
Look at grips, rebound setting and seat height.
Get some surgical spirit from a good chemist and wipe it on your affected area even when the hands are blister free it will help harden the skin, apply with round disc that girlies use to take make up off, apply whilst your hands are hot and sweaty like after a ride when your gloves come off or when you get out of the bath.
I couldn’t use those Palm protectors, they would just break me, although my hands looked like when I used to ride BMX,
Keep us posted and when and where are you going to the Alps?
