Question: Elastic Drawstring? So it has elastic and a drawstring?
Document: Have been using this gi for a month now. Nice and heavy, good snap. Very stiff and sturdy lapel. Washes well and does not wrinkle so bad. Pants do shrink in length. I wahs them in cold and partially dry them in dryer. Usually do not have to iron. Has elastic waist with drawstring, works for me. My son and I both use this gi and like it fine.
I have a family member that teaches karate professionally in another country, but has a hard time finding a supplier for these uniforms locally. I had previously ordered one of these uniforms and she loved it, so I decided to get a couple more for the next time I visited her. The one thing to be careful when ordering this uniform is whether you get the traditional drawstring pants or the modern elastic style.
The only problem is I would have preferred a non-elastic feel to the waist. This is an overall decent gi.
This is a good gi. Comfortable cut, nice material, and it arrived quickly. If the option was available I'd go with a drawstring bottom. Also, I'm 6'2 240lbs and I found a 6 is a little big, even after running it through the wash.
What I really need to comment on is the excellent service from the seller. There was a mix up with my order, and they were quick to call me the same day, and offer a full uniform replacement. That is true customer service people, and that is what will make me a repeat customer down the road. Thank you TMAS for being so awesome.
This is my first heavy weight gii, thus I don't have many other ones to compare it to. However, this gii has everything I wanted from it. It has NOT shrunk even a little after multiple washing/drying cycles. The material is really tough and feels like it will keep on delivering for long, long time. I've used this gii for about three months and I am very happy with it.I also wanted to mention the extraordinary customer service I have received from the TMAS store.
This is a heavy fabric, which is what I was looking for. The color seems to be fading a bit after just a few washings; mostly in lines. I like the feel & anticipate this lasting quite a while
This is a great heavy Gi. I've used it for several months already and have been kick-boxing, grappling and training in it and it wears like iron.
This is a decent heavy weight Gi for the price. I am expecting to get some good mileage out of this uniform considering what I paid for it. I have read some reviews about it being too heavy or too stiff, but its pretty soft for a &#34;Heavy weight&#34; Gi in  my opinion and not as stiff as some of the uniforms I am used to abusing.
I was truly amazed how they have handled my situation. From now on, this store will be my number one choice for all my martial arts needs.
