This is a long-sleeved "Warm Heat Rash" high-performance innerwear from GULL, known for its excellent heat retention and water repellency. Wearing it under a wetsuit helps prevent body temperature from dropping, supporting comfortable diving. ■ Size: Men's L ■ Color: Black ◽️ Usage: Only used once (for diving) ◽️ Condition: After use, it was carefully washed with fresh water, dried, and stored. There are no stains, fraying, or stretching of the fabric, and in my subjective opinion, it is in "like new" condition, very clean. ◽️ Features - Uses far-infrared (FIR) brushed material, providing high heat retention. - Water-repellent treatment allows for quick water drainage after exiting the water, reducing body chill. - Highly stretchable, does not restrict movement during diving. This is a very useful item for diving in the spring, early autumn, or as an inner layer in winter. If you are considering replacing or purchasing a new one, how about it? --- ※ Please understand that this is a used item and has been stored at home before purchasing. ※ Immediate purchase is OK.
