SEAL SL:01 Technical Drysuit

Built for explorers. Trusted by technical divers. Designed without compromise.

When you spend long hours underwater, your drysuit becomes more than just equipment. It becomes part of your life support system.

The SEAL SL:01 has been developed alongside members of the XDEEP Exploration Support Programme and tested in some of the world’s most demanding cave, wreck and exploration environments. Every panel, seam and feature has been designed with one goal in mind: creating a drysuit that is exceptionally comfortable while remaining incredibly durable.

Unlike conventional trilaminate suits, the SL:01 features an innovative dual-shell construction that delivers the flexibility divers want without sacrificing the toughness serious exploration demands. It moves naturally with your body, reduces air trapping, and remains comfortable whether you’re spending hours underwater or carrying heavy twinsets across rough terrain.

Dual-Shell Construction

The SL:01’s unique double-shell design solves one of the biggest compromises in drysuit design.

Most lightweight suits sacrifice durability, while heavy-duty suits often feel stiff and restrictive.

The SL:01 delivers both.

Its advanced trilaminate construction provides outstanding freedom of movement while an outer protective shell absorbs abrasion and wear. The result is a suit that feels remarkably flexible yet is built to withstand years of demanding diving.

SuperFabric Protection Where It Matters

High-wear areas including the knees and forearms are reinforced using SuperFabric®, one of the most advanced protective materials available.

Thousands of tiny resin armour plates provide exceptional resistance to abrasion, cuts and wear while remaining flexible. You get protection comparable to Kevlar without the stiffness, making the suit ideal for cave diving, wreck penetration and technical diving environments.

Additional Cordura reinforcement across the shoulders and upper arms further protects the suit when carrying heavy cylinders or wearing technical harness systems.

Military-Inspired Design

The SL:01 benefits from over twenty years of experience designing equipment for military divers.

Its anatomical cut has been engineered to maximise movement while eliminating unnecessary excess material.

The result is:

• Excellent shoulder mobility
• Reduced air migration
• Less suit squeeze
• Outstanding trim underwater
• Reduced diver fatigue

Whether reaching valve shutdowns or running reels through restrictions, the SL:01 moves naturally with you.

A Smarter Front Entry Zip

Rather than placing the dry zip directly beneath your harness straps, the SL:01 uses an offset front-entry design.

This significantly reduces pressure points created by harness systems while also reducing stress on the zipper itself, extending its lifespan.

The unique zip position also makes getting into and out of the suit surprisingly easy, particularly on small boats or when gearing up in confined spaces.

A protective YKK Vision outer zip shields the main dry zip from abrasion and contamination.

Designed for Technical Divers

Everything about the SL:01 has been designed with practical diving in mind.

Large low-profile 3D Cordura pockets provide plenty of storage without creating unnecessary drag.

Each pocket includes:

• Dedicated wetnotes compartment
• Internal accessory rail
• Easy one-handed access
• Streamlined design that remains flat when empty

Communication slates, backup masks, spools and accessories all have their place.

MOLLE Accessory System

Each forearm features a military-inspired MOLLE mounting rail.

This allows divers to securely attach accessories such as:

• Dive computers
• CCR handset cables
• Cave markers
• Bungee loops
• Navigation tools
• Custom accessories

It gives you the flexibility to configure the suit exactly how you dive.

The result is a suit built to perform season after season in demanding environments.

Why we love it at Global Dive

There are plenty of drysuits on the market, but very few genuinely rethink how a drysuit should perform.

The SEAL SL:01 feels noticeably lighter and more flexible than many expedition-grade suits, yet still offers the durability needed for cave diving, wreck penetration, technical diving and demanding recreational diving.

The thoughtful details, outstanding mobility and premium European construction make it one of the most impressive drysuits we’ve seen in years.

If you’re investing in a drysuit that’s designed to last for many seasons of serious diving, the SEAL SL:01 deserves to be at the top of your shortlist.
