I really like the material on the palm of these. It feels durable, but also thin enough I can actually pinch the skin on my palm. (I wasn't sure how else to explain) As another review mentioned, the velcro comes undone very easily. Like, it barely even tries to hold on. I would return these, but honestly they're great otherwise and I think I'd rather have them as mechanic gloves, or backups before getting rid of them.
One remedy I found that can improve the cling of the velcro is to massage the rubber on the strap until it's soft and supple. The velcro is weak, and the issue is exacerbated by that stiff bit of rubber on the strap which straightens out the velcro and causes it to unstick. Massaging the rubber so it rests in more of a curve shape really helped with it sticking around the curve of the glove. To massage, just pinch it in every spot multiple times and work it until there aren't any spots that resist being bent.
