The 3mm thick AQUA LUNG THERMOCLINE gloves are perfect for diving and snorkeling, and the Velcro wrist strap allows for an adjustable fit. They also come with a hood, which I think will be useful for diving in cold weather! Shipping will be via the safe and secure Rakuraku Mercari service! Please understand that the packaging will be a simple wrapping in a bag and bubble wrap. ^^;
