I used this once when diving at Silfra in Iceland. I believe the total usage time was about 2 hours. It's a rather expensive inner suit for a dry suit that doesn't get much use, so how about this top and bottom set? I will ship it in simple packaging. World Dive Thermal Body Smoother Pullover (World Dive Dry Suit Inner Wear Thermal Body Smoother) Unisex Size L Product Specifications Inner wear for dry suits made with fibers that excel in moisture permeability, water repellency, heat retention, and stretch. The surface repels water and blocks wind while allowing moisture from the skin surface to escape. It also features a surface treatment that allows for smooth donning and doffing, providing a soft feel and a functional design with a three-dimensional cut silhouette that balances ease of movement and comfort. The pullover has a front zipper for smooth donning and doffing, and the trousers have a high waist design to prevent the back from being exposed when sitting, etc.
