My bamboo gardening gloves did not work well for weeding (my fingers wore holes right through the finger tips of the gloves), so I picked these Atlas Grip Gloves up thinking they looked tough and sturdy. It turns out they are.
The only thing I do not like about them is that they are not very breathable (the backs are breathable, but my hands got hot and sweaty), but it is not such a bad trade off for them being so durable. Also, they do not exactly fit like a second skin, but they are comfortable (and flexible) enough, and they really do help with gripping and pulling up weeds.
The Atlas Grip Gloves are supposed to grip just as well wet or dry, but I have used them only on dry weeds, so far. It doesn't rain much at all during the summer here, which is when the weeds grow, so I doubt I'll be able to give an update on how well the gloves grip wet weeds.
The Atlas Grip Gloves are machine washable. I am not sure what material the breathable backs are made of, but the grip palms are "natural rubber latex" (there is an allergy caution). I have run them through the wash cycle once (they were air-dried), and they held up just fine.
The gloves were made in Malaysia. Mine are a size small (I saw mediums in the store, but I am not sure if they are available in large). The ones I bought have green palms with a neutral color back, but I noticed them in blue also.
