Interesting that several of you mentioned having tears etc. with GK leos. All our team leos/warm ups are GK. Last season we had 2 girls who had their leos rip under the arm---and they hadn't done anything except try them on. GK did take them back and had to FedEx 2 new ones since we had a meet coming up. When the assistant coach looked at where they had torn, she noticed there was literally no seam there, so no give at all in the fabric and once they ripped there was no way to repair them.
We had the same thing happen with our competition leos 2 yrs ago when we had Starlight leos (I believe that is the name of the company.) Our coach likes the competition leos to fit like second skin and a lot of the girls started having rips in the underarm area. We had to send back the entire teams leos to have a double reinforced seam put in the underarm area. Those leos were so tight I had to help dd get it on, she could get it up to her waist, but I had to help get it over her shoulders. Let me tell you though, boy did our girls look good! Their body definitions were stand out gorgeous.
This past yr we had GK and the leo was a foil. What a nightmare. When some parents washed the leos (according to the directions) the foil turned a silver grey color (original color was teal). They looked horrible! GK ended up sending our entire team a new leo that wasn't foil. It was basically the same leo but in a different material. There wasn't much WOW factor and to me it looked only so-so.
This yr we are getting Adidas, which if I am correct is actually made by GK (at least the Olympic leotards are that are Adidas. I read that Adidas awarded the contract to GK to make the Olympic leos). I hope we don't have any of the problems that we had before.
These little things costs too much to have something go wrong with them!
