Thank you for taking a look at my many items. FELLOW Heat Max Plus Thermal Inner HM-inner I haven't had a chance to use it, and it doesn't look like I will, so I'm putting it up for sale. Uses the brushed material "Heat Max Plus" used in semi-dry suits. Despite being only 0.5mm thick, it achieves innovative warmth with its high-quality brushed material! Made of neoprene, it can be worn on its own in addition to its role as an inner layer! A wetsuit inner that maintains the best heat retention and dryness. ALL 0.5mm, thermal full inner designed specifically for Japanese people. Doesn't slip and is easy to put on and take off. Water-repellent, heat-retaining brushed type. Gender...Men's Size...ML b2
