I saw all of the reviews and I thought that these sounded just perfect for me - I have waterproof clothing but not gloves, so I wanted them to complete my hiking gear.
The seller (Jackal Outdoors) was excellent and they arrived very quickly - unfortunately, the item was awful. First of all, they're extremely stiff - they reminded me of those hard washing up gloves if you know what I mean! They may have eased up with wearing, but by far the worst part was that the shape of them is like no human hand I've ever encountered!
The fingers are very tight, but the palm is huge so what happens is that it folds up as you close your hand, leaving a big baggy part around your little finger joint. Because the fingers are so tight, it starts to cut off the circulation which makes your hands colder, not warmer!
I did follow the instructions and measure my hand before purchasing (21cm) and I bought medium rather than large which would have been my instinctive choice. I can only really recommend these if you have massive palms and tiny thin fingers (but not too long as mine were right at the ends).
On the plus side, the wrist grips seemed nice and tight and I'd imagine they do keep out water as they're basically washing up gloves - sadly I didn't try it myself as I sent them back. Shame but I have to be honest, I wouldn't recommend these.
