Product Information

The Waterproof U1 2/5mm HAVS Hooded Vest for Women is an attached-hood neoprene undervest built from 100% MICROCELL CR neoprene that adds core and head warmth beneath a wetsuit, with Waterproof's HAVS (Hood Air Venting System) venting trapped air through two valves in the hood.

Who it is for

This vest is designed for women divers who want an extra insulating layer under their existing wetsuit rather than a standalone exposure suit. It is built to fit under any suit that does not already have its own hood, giving a diver a way to add core and head warmth without switching to a thicker primary wetsuit.

Key details

  • Thickness: 2/5 mm neoprene construction.
  • Material: 100% MICROCELL CR neoprene.
  • Hood: Attached hood with H.A.V.S Hood Air Venting System, which evacuates air through two valves.
  • Construction: Anatomically sculpted panels and bonded high quality nylon thread seams.
  • Fit: Women's fit, designed to fit under all suits that do not already have a hood.

Compatibility and sizing

The U1 Hooded Vest is offered in women's sizes XS (X-Small), S (Small), M (Medium), ML (Medium Large), L (Large), and XL (X-Large). It is intended to fit under any wetsuit that does not already include its own hood.

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 sizes does the Waterproof U1 Hooded Vest for Women come in?

The Waterproof U1 2/5mm HAVS Hooded Vest for Women is offered in six sizes: XS (X-Small), S (Small), M (Medium), ML (Medium Large), L (Large), and XL (X-Large). Choose based on how the vest will layer under your existing wetsuit.

Will the Waterproof U1 vest fit under my current wetsuit?

Yes, the U1 Hooded Vest is designed to fit under any suit that does not already have its own hood. It is built as an undervest rather than a standalone exposure suit, so it layers beneath your existing wetsuit.

What is HAVS on the Waterproof U1 hood?

HAVS stands for Hood Air Venting System, a feature on the U1's attached hood that evacuates trapped air through two valves. This is built into the hood itself rather than being a separate accessory.

Is the hood on the U1 vest attached or separate?

The hood on the Waterproof U1 2/5mm HAVS Hooded Vest is attached directly to the vest, not a separate piece. It includes the HAVS venting system with two valves as part of that attached hood.
