The NeoSport 5mm Men's Neoprene Back Zip Full Wetsuit (SKU: S850MB) is a high-performance thermal jumpsuit designed to maintain core body heat in cool-to-cold water environments.
Built with 5mm premium foam neoprene and tailored specifically to male anatomical contours, this suit offers an optimal balance of deep thermal insulation, durability, and flexibility for scuba diving, snorkeling, and surface watersports.
These suits are warm, comfortable, and durable, and are perfect for all cold-water activities.
Both men’s and women’s suits feature adjustable collars as well as flexible knee pads for abrasion resistance.
The adjustable collar on both men’s and women’s suits provides a comfortable, non-confining stretch fit.
The ultra-versatile 5mm is great for tropical waters, especially in the winter months, yet is also warm enough for the cooler temps of dive sites closer to home. A 5mm torso promotes core body warmth and 5mm extremities balance warmth and flexibility. This proven jumpsuit design is easy to don and has an adjustable collar that inhibits water exchange at the neck. Tough, flexible pads protect the knees and lower leg. Generously cut heavy-duty #10-YKK back zipper with pull tab leash for easy self-donning-and-doffing. The NeoSport Jumpsuit has an adjustable hook and loop fastener collar that provides a comfortable, non-confining stretch fit.
Flexible thermal bonded knee pads for abrasion resistance, Protect the high-wear areas of the lower legs. With an anatomical cut pattern, this NeoSport suit is soft warm, comfortable and durable. All seams are glued-and-sewn; spot tapped at intersecting seams with spandex trimmed wrist and ankle seals all making this a strong and durable suit design for seasons of reliable service. Suit is made from nylon 2 neoprene rubber, comes equipped with an internal key pocket for security, tear away sizing tags, is black or black/blue in color, and is available in multiple sizes.
5mm Core Thermal Protection: Constructed with 5mm premium foam neoprene throughout the body to deliver reliable warmth in cool water conditions (approx. 55°F–70°F / 13°C–21°C).
Anatomical Men's Cut: Engineered with multi-panel shaping specifically designed to match male body proportions, eliminating dead space and preventing cold-water pooling.
Glued & Blindstitched (GBS) Seams: Every seam is double-glued and blindstitched to form a tight, watertight seal that minimizes water circulation and holds body heat inside the suit.
Corrosion-Resistant #10 YKK Back Zipper: Equipped with a heavy-duty YKK back zipper and an extra-long pull leash for quick, effortless self-donning and doffing.
Thermal Webbed Back Flap: Features an internal zipper flap (water barrier) behind the back zipper track to restrict cold-water flushing through the teeth and shield the spine.
Adjustable Collar Seal: Designed with an adjustable hook-and-loop collar that seals smoothly against the neck to reduce water entry without causing constriction.
Thermal Bonded Knee Pads: Reinforced with flexible, high-abrasion Thermal Bonded knee pads that protect the suit against wear from boat ladders, rocks, and gear without restricting leg movement.
Internal Key Pocket: Features an integrated internal key pocket to safely store keys during water sessions.

Wetsuit is nice and is warm enough. The legs are a little tight, but that is because I have really big calves and thighs. Could have used a 4X but that may have been too big (if they even sell it).

I'm a rec and tech instructor and have been diving Neisports for many years. They are, overall, very good wetsuits for the money. No frills, no extra zippers, but get the job done. My only complaints, wish there was a little more padding on the knees as the vinyls overspray wears out quickly and the neoprene around the neck will begin to split after a couple of years of hard use. But at that price point, I just buy a new one.

I wish I could give this suit 0 stars! This is the worst suit I ever bought... and I've boughten many. I've been diving since 1971. It was good in the beginning and slowly turned into a SPONGE! Very bad neoprene. It drips drying for hours and weighs many extra pounds of water when you exit. I believe this suit is made by Henderson and makes me question their other products. If you are an avid diver, I do not recommend.
