Poorly designed gloves. Avoid.

I bought these gloves to replace older gloves, a brand.
First problem: thumbs. I am a man with large hands, and I took the larger model, saying it would go. Eventually I had done some sewing gloves to open the thumb and stop the seams on each side of the thumb.

Second problem yesterday on my first test pool: for breaststroke, no problem because at any moment the hands are under water, but for the crawl, cloth gloves being waterlogged, whenever I left the water arm, the glove had a tendency to remove and when I plunged back, the next moment, the glove in my hand and went back ached at the joints between the fingers.
In short, it is a disaster.
