Henderson Aqualock — Semi-Dry Performance from a Wetsuit System
The gap between a wetsuit and a drysuit has always been wide — a wetsuit floods at every opening, while a drysuit is a different category of equipment, cost, and training entirely. Henderson's Aqualock system sits deliberately in that gap. It's built around interlocking openings at the wrist, ankle, and neck that mate precisely with matching Aqualock hoods, boots, and gloves — dramatically reducing the water flushing that happens at every opening of a standard wetsuit, without the complexity, cost, or buoyancy management of a full drysuit.
The result is genuinely semi-dry performance: water that does get in stays largely where it entered rather than continuously flushing in and out with every movement, which means your body only has to warm that initial layer once rather than repeatedly. For divers who dive regularly in cool-to-cold water but aren't ready to invest in (or train for) a drysuit, Aqualock is a meaningful step up in thermal performance from a standard wetsuit.
At DiveCatalog.com, we carry the current Henderson Aqualock lineup: Quikdry fullsuits, bib hoods, and gloves in multiple thicknesses. DiveCatalog.com is an authorized Henderson dealer.
The Aqualock Range
Aqualock Quikdry Fullsuits — 3mm and 5mm
The Aqualock Quikdry fullsuit is the core of the system — a wetsuit built around Henderson's interlocking seal technology at the wrist and ankle openings, designed to integrate with the matching Aqualock hood and gloves for a continuous, low-flushing seal from head to hands to feet. Available in 3mm and 5mm thicknesses for men. The Quikdry naming reflects the fast-drying fabric construction, a practical benefit for divers doing multiple dives in a day or traveling without reliable drying time between sessions.
Aqualock Quikdry Bib Hoods — 3mm, 5/3mm, and 7/5mm
The bib hood is the piece that completes the Aqualock neck seal — a hood with an integrated bib that tucks under and interlocks with the fullsuit's collar, closing off the gap that a standard separate hood and wetsuit collar leaves open to flushing. Available in 3mm, 5/3mm, and 7/5mm configurations to match different fullsuit thicknesses and cold-water demands.
Aqualock Quikdry Gloves — 7mm
The Aqualock glove uses the same interlocking wrist seal concept to mate directly with the fullsuit's wrist opening, closing off one of the most persistent flushing points on any wetsuit. Available in 7mm for serious cold-water hand protection.
Building a Complete Aqualock System
Aqualock is designed as a matched system rather than standalone pieces — the thermal benefit comes specifically from the interlocking fit between the fullsuit and its matching hood and gloves. A fullsuit paired with a non-Aqualock hood or gloves will still function as a wetsuit, but won't deliver the reduced-flushing benefit the system is built around. When ordering, match your fullsuit thickness to a compatible bib hood (e.g., a 3mm fullsuit pairs naturally with the 3mm bib hood) for the most effective seal.
Who Is Aqualock For?
| Diver Type | Recommended Configuration | Key Reason |
|---|---|---|
| Regular cold-temperate divers not ready for a drysuit | 5mm Quikdry Fullsuit + matching bib hood + gloves | Semi-dry thermal performance without drysuit cost, training, or buoyancy complexity |
| Divers doing multiple dives per day | 3mm Quikdry system | Fast-drying fabric construction speeds turnaround between dives |
| Cold-hand-sensitive divers | 7mm Aqualock Glove paired with fullsuit | Interlocking wrist seal closes the most common flushing point |
| Divers wanting maximum head/neck seal | 7/5mm Bib Hood | Heaviest hood option for the coldest neck and head exposure |

Frequently Asked Questions — Henderson Aqualock
What does Aqualock actually do differently from a regular wetsuit?
A standard wetsuit relies on a snug fit at the wrist, ankle, and neck to limit water flushing, but water still moves in and out with every joint movement. Aqualock uses interlocking openings that mechanically mate the fullsuit to matching hood and gloves, closing those gaps far more effectively and significantly reducing ongoing water exchange — delivering noticeably better thermal performance than a standard wetsuit seal at the same thickness.
Do I need the matching Aqualock hood and gloves, or can I use my own?
The reduced-flushing benefit specifically comes from the interlocking fit between the Aqualock fullsuit and its matching Aqualock hood and gloves. A non-Aqualock hood or glove will still work with the suit as a standard wetsuit, but won't achieve the same semi-dry seal performance.
Is Aqualock the same as a drysuit?
No. Aqualock is a semi-dry wetsuit system — it significantly reduces water flushing compared to a standard wetsuit, but it doesn't keep you fully dry the way a drysuit does. It doesn't require drysuit-specific training or buoyancy management, making it a more accessible step up in thermal performance for divers who dive in cool-to-cold water but don't want the complexity of a full drysuit system.
What does Quikdry mean?
Quikdry refers to the fast-drying fabric construction used throughout the Aqualock line — useful for divers doing back-to-back dives in a day, or traveling without reliable time to dry gear between sessions.
