Product Information

The Waterproof 3D Mesh Vest Men is a thermal constant-volume undergarment worn as an extra layer under a drysuit for core warmth. Triple-layer 3D mesh panels on the front and back create an 11mm constant-volume air gap that insulates when submerged and vents heat on the surface. The vest closes with a high-quality YKK Vislon #5 front zipper.

Who it is for

This vest suits drysuit divers who want a dedicated core layer for cold or variable water temperatures rather than relying on a single thick undergarment. The extra-long back panel is cut to cover the kidneys and the areas that are normally compressed by a weight belt, so it also works well for divers who spend long bottom times in a drysuit and want consistent warmth across the dive, from surface entry to depth.

Key details

  • Front and back panels: triple-layer 3D mesh, 11mm total thickness, creating an 11mm constant-volume insulating air gap
  • Side and shoulder panels: dual-layer 2x3mm stretch 3D mesh for body-shape adaptability and freedom of movement
  • Mid-layer mesh: 70 Denier 3D mesh, the same material used in the D1X Hybrid suit lining
  • Closure: YKK Vislon #5 front zipper
  • Technology: patented D1X ISS Hybrid construction
  • Article number: 4301

Compatibility and sizing

The vest is made for men and is offered in XS, S, M, ML, L, XL, 2XL, and 3XLT+ so divers can match the fit to their body type and layering needs under a drysuit.

Frequently Asked Questions

What thickness of dive boots, gloves, or hood should I choose?

As a general rule, thicker neoprene insulates more, so colder water pushes you toward thicker accessories, but fit, dive length, and personal cold tolerance matter as much as the millimeter number. Divers commonly lose a great deal of heat through the head, so a hood is often the highest-value warmth upgrade for the money. Remember that every added piece of neoprene also adds buoyancy you will need to account for.

How should dive boots fit?

Boots should fit like a snug athletic shoe, with no heel lift and no crushed toes; a little water inside is normal, a sloshing pocket is not. Try them on with the socks you would actually dive, and remember your fin foot pocket has to accommodate the boot. Hard-sole boots protect on rocky shore entries, while soft-sole boots are lighter and pack smaller for boat and travel diving.

How should dive gloves fit?

Gloves should be snug across the palm with fingertips reaching the ends without bunching, since trapped air and loose fingertips destroy dexterity. Thicker gloves are warmer but make buckles, clips, and inflator buttons harder to operate, so choose the thinnest glove that keeps you comfortable in your conditions. Try working a clip or buckle while wearing them before you commit.

How should a dive hood fit?

A hood should seal around the face and neck without restricting your throat or jaw, and lie flat on your head without pulling the mask strap out of position. A loose hood flushes cold water continuously, while an overly tight one is distracting and uncomfortable. Many hoods have a vent to release air trapped during descent, so check yours and burp out any trapped air before you go down.

Why does new neoprene feel so tight?

New neoprene compresses and relaxes with use, so a boot, glove, or hood that feels firm out of the packaging usually settles slightly after a few dives. It should still be snug afterward rather than loose, because neoprene that stretches into a loose fit was probably oversized to begin with. Buy for a snug fit when new, but never for a fit that restricts circulation or breathing.

Do I need to change my weighting when I add a hood, gloves, and boots?

Yes, because every piece of neoprene you add is buoyancy, and a hood, boots, and thick gloves together can shift your weighting noticeably. Do a proper buoyancy check any time you change your exposure protection rather than assuming your usual weight still works. The weight-check procedure is covered in your training, and a dive professional can help you re-do it.

How do I care for dive boots, gloves, and hoods?

Rinse them inside and out in fresh water after every dive day, since they hold sweat and salt more than any other gear, and dry them fully inside-out before packing. Dry them out of direct sunlight and never on a heater, because heat hardens neoprene and weakens glued seams. Store them dry and unfolded, as damp neoprene sealed in a bag is how gear picks up a permanent smell.

What does "constant volume" mean on the 3D Mesh Vest?

Constant volume means the 3D mesh panels hold an 11mm air layer around the torso, keeping insulation stable from the surface to depth. This keeps insulation performance stable from the surface to depth and helps maintain predictable buoyancy characteristics as pressure changes during the dive.

How do I pick the right size for the 3D Mesh Vest?

The vest is sized XS, S, M, ML, L, XL, 2XL, and 3XLT+ for men, so choose based on your normal clothing size and the layering you plan underneath. Because it is worn as a core layer under a drysuit, allow for the undergarments you plan to wear with it.

Why does the vest use a YKK Vislon #5 zipper instead of a coil zipper?

The vest closes with a high-quality YKK Vislon #5 front zipper, the front closure specified by Waterproof for this layering garment.

Is the 3D Mesh Vest only for drysuit diving?

The vest is designed and built as a drysuit undergarment layer, using its constant-volume 3D mesh panels to insulate under a drysuit shell. It provides ventilation on the surface and insulation once submerged, which is the behavior drysuit divers rely on for consistent core warmth during a dive.
