Hollis DX-300X Expedition Drysuit
Designed by technical divers for technical divers and developed over three years in the most demanding conditions, the Hollis DX-300X represents the benchmark in expedition-grade trilaminate drysuits. Combining extreme tear resistance with unmatched flexibility, the DX-300X keeps you completely dry, maneuverable, and comfortable across long runtimes in cold Canadian waters.
Exceptional Built-In Value (Over $600 CAD in Standard Inclusions)
Many expedition drysuits charge premium upgrade fees for modular ring systems and utility storage. The DX-300X comes fully equipped out of the box with zero hidden upgrade costs:
- Factory-Installed SiTech Neck Tite System: Swap blown neck seals on the dive boat in under two minutes—no glue, messy solvent, or workshop wait times.
- Factory-Installed SiTech Quick Cuff Wrist System: Effortlessly replace torn wrist seals on the fly, or quickly integrate dry glove systems for sub-surface winter diving.
- Hypoallergenic Silicone Seals Included: Soft, comfortable, and UV/ozone resistant seals pre-fitted at both neck and wrists—no latex allergic reactions.
- Dual Large Bellows Tech Thigh Pockets: Two cavernous utility pockets equipped with stainless D-rings, bungee loops, and heavy-duty Velcro closures included as standard equipment.
Advanced 3-Layer Trilaminate Construction (700 g/m²)
- Outer Layer: Heavy-duty Nylon Cordura delivering superior puncture resistance and an incredible tear strength exceeding 300N.
- Middle Core (Butyl Mass): 12 independent layers engineered for long-term water integrity with exceptional ozone and chemical resistance.
- Inner Liner: Silk-weave polyester providing next-to-skin softness, friction-free donning and doffing, and rapid moisture management.
- Patented BIAS Cut & Telescopic Torso: Panels cut on the material bias offer 25% more diagonal stretch than traditional trilam, streamlining fit and eliminating internal air migration.
Key Expedition Features
- Low-Profile YKK Flexible Zipper: Diagonal front-entry composite zipper enhances chest mobility and self-donning capability without stiff plastic teeth.
- Rugged Knee Protection: Double-thickness reinforced kneepads handle rocky shore entries, gravel beaches, and rough dive decks.
- Warmth & Ergonomics: Includes 5mm compressed neoprene socks (ready to pair with standard rock boots) and fully adjustable internal suspenders for an aligned, balanced fit.
- Seam Integrity & Safety: Wide flat seam taped construction minimizes leak vulnerability in high-stress zones, accented with 3M reflective safety panels for clear diver visibility.
