Product Information

The Aqua Lung Seawave Dive Hood 3/1mm is a unisex neoprene dive hood that combines 3mm neoprene over the skull with 1mm neoprene at the neck and bib, so insulation sits where heat loss is greatest while the neck stays free to move. It is offered in Black/Blue in sizes XS through XL.

Who it is for

This hood suits recreational and travel divers who want head warmth without the stiffness of a uniform thick hood, and anyone who finds a heavy neck section restrictive while breathing or turning their head. The thinner 1mm neck and bib section lets the neck move freely, while the standard stretch neoprene pulls on without fighting the ears. Because the face seal is left unbound, it also works well for divers who have never found a stock hood that seals cleanly around their own face shape.

Key details

  • Thickness: 3mm skull panel, 1mm neck and bib.
  • Material: standard stretch neoprene for durability and an easier pull-on over the ears.
  • Seams: flat-lock stitched so they sit flush against the skin and limit chafing under a wetsuit collar.
  • Face seal: unbound, so it can be trimmed to a custom fit.
  • Storage: hanging loop for drying and storage between dives.

Compatibility and sizing

Five sizes are available: XS (NE1440140XS), S (NE1440140S), M (NE1440140M), L (NE1440140L) and XL (NE1440140XL), all in Black/Blue. A hood should seal around the face and neck without restricting the throat or jaw and should lie flat enough that it does not push your mask strap out of position. Choose the size that is snug rather than loose; contact us if you are between sizes.

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 the 3/1mm rating on the Seawave hood mean?

It describes two neoprene thicknesses in one hood. The skull panel is 3mm, which is where divers lose the most heat. The neck and bib are 1mm so the neck can move freely, while the standard stretch neoprene pulls on without fighting the ears. The result is targeted warmth over the head without a thick, restrictive collar under your wetsuit.

Can I trim the face seal on the Aqua Lung Seawave hood?

Yes. The face seal is left unbound specifically so it can be trimmed to a custom fit. Trim conservatively, a small amount at a time, and test the seal in the water between cuts, because material cannot be put back. The goal is a seal that closes around the face without pressing on the throat or jaw or shifting your mask strap.

What sizes and colors does the Seawave 3/1mm hood come in?

The Seawave 3/1mm hood is available in a Black/Blue colorway in five unisex sizes: XS, S, M, L and XL. Part numbers run NE1440140XS through NE1440140XL. If you are between sizes, call DiveCatalog at 888-701-4017 and we can talk through how the hood should sit relative to your mask strap and wetsuit collar.

Will the bib on this hood work under my wetsuit?

Yes. The hood has a 1mm neck and bib section, and its flat-lock stitched seams sit flush against the skin to limit chafing under a wetsuit collar. The flat-lock stitched seams sit flush against the skin, which limits chafing where the collar overlaps the bib.
