Mobility and Comfort

Unrestricted Movement for Shore Dives

The Hollis DX-300X is designed with the diver’s comfort and mobility in mind, making it an excellent choice for shore diving.

The suit’s construction allows for a remarkable range of motion, which is immediately noticeable when entering and exiting the water from the shore.

The combination of the BIAS cut and telescopic torso provides flexibility without sacrificing a streamlined fit, ensuring you can move freely and comfortably throughout your dive.

Zipper Protection

Protected and Easy-to-Use Zipper

The Hollis DX-300X features a strategically placed YKK zipper that wraps around the right hip for easy access.

To protect this crucial component from sand, grit, and other debris, a durable velcro flap provides an extra layer of security.

This thoughtful design detail not only extends the life of the zipper but also ensures it remains easy to operate, allowing you to get in and out of your suit without a struggle.

Design and Protection

Smart and Protective Front Design

The front of the Hollis DX-300X showcases a design that is both functional and visually striking.

A prominent velcro strap not only adds to the suit’s aesthetic but also serves the practical purpose of protecting the main zipper and the innovative Si-Tech Neck Tite seal.

This attention to detail in the suit’s construction ensures that key components are shielded from wear and tear, enhancing the suit’s overall durability and reliability.

Fit and Flexibility

Telescopic Torso for Custom Fit

The Hollis DX-300X incorporates a telescopic torso design that allows for a customized fit and enhanced flexibility.

This feature, combined with the suit’s suspenders and crotch strap, pulls the fabric in for a closer, more streamlined profile.

The result is a suit that moves with your body, reducing air migration and improving buoyancy control for a more comfortable and efficient dive.

Durability and Versatility

Reinforced Knees and Boot Compatibility

The Hollis DX-300X is built to withstand the rigors of diving with its heavy-duty nylon Cordura ripstop material and double-thickness knee pads. These reinforced knees provide exceptional durability and protection in high-wear areas. While the suit comes with neoprene socks, it is also compatible with rock boots, as demonstrated here, offering divers the versatility to choose the footwear that best suits their diving environment.

Ease of Use

Effortless Donning and Doffing

Getting into and out of a drysuit can often be a challenge, but the Hollis DX-300X makes the process remarkably easy. The combination of the soft, silicone neck seal, the clever placement of the YKK zipper, and the overall flexibility of the suit’s design makes donning and doffing a pleasant experience. This ease of use is a significant advantage, especially for divers who are new to drysuits or who value convenience.

Neck Seal System

Innovative and Comfortable Neck Seal

The Hollis DX-300X features the industry-leading Si-Tech Neck Tite system, which provides exceptional comfort and a user-replaceable seal.

This innovative design makes it easy to change a torn or damaged seal in minutes, a huge advantage for divers on multi-day trips. While the lack of a neck gaiter means less thermal protection, the trade-off is a more comfortable and less constrictive fit around the neck.

Overall Appearance

Ready for Your Next Dive

The Hollis DX-300X is a sharp-looking suit that will have you ready for any dive adventure. Its sleek, black design with subtle red accents gives it a professional and modern look. When fully kitted out, the suit’s streamlined fit and thoughtful design features are on full display, showcasing a drysuit that is as stylish as it is functional.

What other customers say:

This is my second purchase from DRIS and I couldn't be happier. I sent my drysuit in for inspection and repair and they were really easy to deal with, responsive, and did a great job.

I had an item back ordered and they were quick to let me know and give me the choice to wait for everything or send it in two packages. Great customer service and sense of humor! (They have the best "your order has shipped" emails)
