I've checked out our local store and wasnt really sure what I shoudl be going for. The choices range from a basic 'Kiai' single weave gi through to an Adidas Champion gi (3 x the price) Here is some of the info about the one I was checking out: 650gm 100%Brushed Cotton Gi Heavy Collar. Reinforced and covered seams on jacket and pants. Full length padding on knee. The Adidas gi is a bit over 900grams and double weave. Though it seems insane to pay 3 x as much (possibly just paying for the brand ??) Anyhow, any one have any recomendations on things to be aware of, ?? what about sizing? is it all based off height ?
