These are unisex design so men should wear their regular Sherpa size, while women should size down (eg. women's M = unisex S). Also, please note the extra secure waistband will feel tighter initially but relax over time.
"Perfect for running Hong Kong 100 without a backpack. I fit three soft flasks, rain jacket, phone, poles, head torch and gels, and all with zero bounce."
- John Ellis, 14 time Hong Kong 100 Finisher and Co-Founder of T8
