Speedo for boys,
This review is from: Speedo Boys' Essentials Endurance+ Jammer (Apparel)
I measured my son's waist but had to go up 2". This meant returning the first pair which was 1" bigger and was what I thought other reviews had recommended. After using the new bigger pair, I think I may have washed the item amoung a 40degree wash and that it shrunk a bit. I therefore recommend sticking to the 30 wash.
