These are the best dive gloves around. I'm a really big fan of Fourth Element products. They are very well made, good quality & well thought out, especially for cool/cold water divers.
I had to borrow a random pair of gloves recently & they were so ill-fitting that water was washing in & out of them taking all my heat away, I could barely make anything but an 'okay' signal & my fingers weren't even in the finger part of the gloves! It made me appreciate my own pair a lot more.
The 'Fourth Element 5mm Dive Gloves' have grip/tread-like material all over making using BCD controls underwater much easier; they are very snug fitting, meaning that you warm the water around your hand & it stays there keeping you warm; & they give you excellent dexterity to make kit adjustments, hand signals, or even Pulp Fiction-type dance moves I discovered recently! Obviously being 5mm thick is going to make you feel a bit like you have sausage fingers, but it really makes all the heat difference after 20 minutes in British waters.
Just a small note: Fourth Element can be quite unusual in their sizing. I have very small slim hands/wrists & I find that the 'Small' only just fits me. I can only imagine that the 'Extra Small' must be for children. It might be best to try-before-you-buy or make sure you can do size exchanges if you aren't sure.
