In order to maintain power in your stroke you need to be able to feel the paddle in your hands; the Sea To Summit Paddles Gloves ensure your hands and digits stay warm.
Stretchy, insulating neoprene maintains warmth and helps eliminate blistering
Pre-bent fingers help with dexterity to ensure you maintain a solid grasp
Grippy pattern on the palm is tacky to help maintain grip of the paddle
Familiarity: I've used it once or twice and have initial impressions
Only had to use once. But, it was in Utah in February. Below Freezing river and air temp just above freezing. Kept the digits cold on my multiple swims due to it being my first outing on the kayak, ever.
