Any recommendations for bum bag type for a petite size 8 female - certainly isn’t for me more the other half
I have various waist packs I use for hiking - not tried them cycling yet though. It really depends how much you want to carry in one and how you want to carry water (I always prefer a bottle myself). The brands I can recommend are:
Salomon - good for small ones (intended for running) - women UK link
Mammut - Lithium waistpack or Tasch (in various sizes, flexible shoulderbag that also fits on your own belt) - Mammut UK
Mountainsmith - great for larger waistpacks up to 15L or so! - Mountainsmith USA but can buy on Amazon
