I used these to kayak 34 miles in 2 days and they were brilliant. I had no blisters, did not get too hot and could still do all the nimble fingers things fingerless gloves are good for. In case you're wondering my hands are soft and easily blistered, without gloves I blister at about 4 miles so these made a huge difference and were comfortable wet as well as dry.
Bought these gloves for sailing as i usually run through gloves quickly racing every weekend and these have been the only gloves to withstand more than one season!
No concerns here. I used it for a kayak trip for which they worked perfectly.
My son has been using these for his DoE canoeing expedition and they've been great for protecting his hands.
Good protection but easy to move your finger in.
