Description
Description
Hollis DX-300X Technical Expedition-Grade Drysuit is designed by technical divers, for technical divers. Developed over three years in demanding conditions, it delivers maneuverability and comfort while maintaining long-wearing durability for serious scuba and diving missions. The suit integrates a heavy-duty outer layer, a multi-layer water barrier, and a soft inner liner to balance warmth, mobility, and reliability in challenging environments.
The DX-300X combines a 12-layer Butyl Mass core with an outer Nylon Cordura shell, achieving dependable water tightness and resistance to chemicals and ozone. An inner silk-weave polyester liner offers easy donning and comfortable wear for extended dives, while the patented BIAS cut with a telescopic torso increases freedom of movement and reduces air migration. Wide flat seam construction minimizes leak-prone areas for safer diving gear performance.
Designed for expedition diving, it integrates a low-profile YKK zipper and SiTech silicone seals, including Neck Tite and Quick Cuff wrists, to maintain a secure seal and smooth operation under water. Practical features include two large Velcro bellows pockets with internal D-rings, double-thickness kneepads, 5mm neoprene socks, and adjustable suspenders for a tailored fit across conditions.
