GI weights?

[opr1945]

I have been looking at different brands of GIs for sale. I have noticed that one brand will list it's 10 oz GI as middle weight while another will list it's 10 oz GI as hea vy weight. How can the same weight be light, medium or heavy weight?

It is up to the manufacturer.

Keikogi weight is yet to be codified and then standardised by the ‘International Bureau of Weights and Measures’ (Bureau international des poids et mesures) but I’m sure it’s on their to do list.

My previous above was posted by accident and is unfinished. I apoligize for my error.

Please me change slightly my question from when I first posted this thread.

I see that many manufactures/sellers advertise light weight GI's as student GI's, 6, 8 or 9 oz. But experienced practitioners seem to think heavier 12 or 14 oz Gi's are more desirable. It would see me, being a new-be and all, That the heavier fabric would require more effort and take more energy than lighter fabric. And also be warmer and less breathable and result in more swearing.

What am I missing?

Go by the weight in ounces. Ignore "medium weight," "heavy weight," etc whenever you're dealing with non-Japanese made gis.

Japanese-made gis are more consistent in this regard. I.e.,

Heavy weight = #10 cotton (which is 12 oz)
Middle weight = #11 cotton (which is 10 oz)

Light weight is the only one among Japanese brands that is not consistent.

Shureido claims that Japanese cotton cannot be measured in ounces, but Tokaido debunks this.

BTW, if you're training in an Okinawan style (i.e., Uechi-ryu), you should probably be wearing a Shureido anyway. It has a unique cut to it that's optimized for Okinawan styles (as opposed to slimmer cut brands, such as Tokaido and Shobu which are optimized for Japanese styles). If you want to save a few bucks, Tokyodo International has a similar cut to Shureido (notable exception being that the jacket is not as long). That's the brand that I wear.

Some may disagree, but I don't recommend training in anything heavier than 12 oz. Anything heavier should be a "special occasion" gi. Just my opinion, though.

Lightweight gis (that are not designed for kumite) should only be worn as a low investment for beginners, unless you don't mind seat-soaked fabric sticking to your skin.
