This is the Henderson Men's 3mm Thermoprene Front Zip Long Sleeve Shorty Wetsuit

Features:

• The ultimate in utility, this Long Sleeve Jacket is most often paired with a john or jane for full-length protection and outstanding core warmth, but worn alone it's an ideal companion for warmer conditions.
• The use of high-quality, compression resistant neoprene insures it will keep you warm dive after dive and a higher-stretch quotient than standard neoprene makes donning and layering a breeze.

The ultimate in utility, this Long Sleeve Jacket is most often paired with a john or jane for full-length protection and outstanding core warmth, but worn alone it's an ideal companion for warmer conditions. Long sleeves increase both warmth and abrasion protection from diving's natural bumps and scrapes. Available in three thicknesses, this Shorty/Jacket can be mixed and matched with any other suit to accommodate a wide range of diving conditions. The use of high-quality, compression resistant neoprene insures it will keep you warm dive after dive and a higher-stretch quotient than standard neoprene makes donning and layering a breeze.
