Gi weight-whats the diffrence?

[marie curie]

I have a light and middle weight gi, and my fiance has a heavyweight.

During the summer, we work out in a room that probably gets to be about 95 degrees, so lightweight is better for then- I know I know the material is supposed to be better on the mid weight, but it doesn't matter, the lightweight is the coolest (note: I also wear a rashguard under, so that may make the diff.)

During the rest of the year (which is most of it, here in Pittsburgh, PA, USA) I use my midweight, because we do some light grappling and those lightweights do tear pretty easily.

As for color:

When you start at our dojo, we give everyone the lightweight white gi's. They usually last people about a year or so, and then they start to look really thin. I bought a white middle-weight gi before off karatedpot.com and I did not like it. Luckily I am in the black belt club so I get to wear a nice black gi.
