Arctic 100 Inner Suit Price: ¥30,800 (¥28,000 excluding tax) This is a new inner suit for drysuits from Aqualung. It's thin and lightweight, but provides high insulation. It's primarily designed for shell-type drysuits, but it seems it can also be worn with neoprene suits. Used for 2 dives x 2 days. Of course, it has been washed and is in excellent condition. It feels a little small (the length is a bit short?), so it's recommended for people under 175cm tall. Outer fabric: 50% nylon, 50% polyester Insulation: Uses 3M Thinsulate, which is thin but highly insulating and warm Lining: Fleece material Mesh ventilation is placed under the left armhole to quickly expel excess air from the inner suit through the drysuit's exhaust valve. Elastic ankle straps and thumb loops prevent the inner suit from riding up when wearing a drysuit. M size: Suitable height: 172-181cm, weight: 70-89kg (manufacturer's specifications)
