The Psycho Tech 3mm Gloves are great for chilly waters and blocking the wind thanks to TechnoButter 3. You'll appreciate the added liner of TechnoButter Firewall which retains heat and quickly dries between surf sessions and the O'Ring seal that prevents flushing. These gloves are super durable and warm. They have a snug fit and we suggest you size-up from your normal size if you don't prefer a tight glove. With a little time, 1 - 2 years, these gloves will form fit to your hand.
