Less Is More

The crotch is one of the most critical stress points in a wetsuit—an area that must endure constant load and movement. N-Cro Tech was developed as a precise answer to that challenge, designed to fully harness the exceptional stretch of premium Japanese materials.

This patented, no-seam crotch system is built into every 4Dimensions Wetsuit, enhancing freedom of movement while significantly improving durability. Its innovative asymmetrical design is immediately recognizable—but its true value is felt, not seen.

Signature chest zip enclosure designed to ease entry while reducing water intrusion - without sacrificing mobility. The ergonomically curved enclosure allows the zipper to glide smoothly from the center of the right shoulder, creating generous space for easy entry and exit.

A YKK Soflex stretch zipper integrates seamlessly with the suit, flexing naturally with the body and supporting movement in the water.

A classic back-zip design refined with an extended outer barrier that shields the zipper end and surrounds the back of the neck, helping to minimize water intrusion. An enlarged inner placket adds another layer of protection, quietly enhancing warmth and comfort.

The placket is finished with a tonal 4D logo - subtle, considered, and unmistakably intentional.

The long chest zip enclosure is designed for effortless entry, particularly in thicker materials. An ergonomically curved zipper runs from the upper right arm across to the upper left arm, creating ample space for easy entry and exit while fully sealing the chest to minimize water intrusion.

A YKK Soflex stretch zipper, combined with thermocompression-bonded stretch tapes, works in unison to reduce water absorption and preserve unrestricted movement.

Water enters a wetsuit through its openings - at the cuffs, ankles, and neck. To address this, 4Dimensions integrates latex water blocks at the cuffs and ankles, maintaining a precise seal that helps prevent water intrusion. It’s a simple, secure blocking system - quietly effective, and easy to appreciate once you’re in the water.

Anti-crack Jersey HTX (Hard Tex) reinforces the knees - areas constantly subjected to abrasion and stress. Visually, it sits flush with the surrounding jersey panels, maintaining a clean, uninterrupted look. Beneath the surface, however, it offers durability far beyond that of standard stretch materials.

The neck opening is folded inward to create a doubled seal, effectively reducing water entry. Using a non-brushed, highly elastic jersey at the neckline, the dual-layer water block maintains a smooth, low-friction feel while preventing irritation and rash. A subtle structure, designed to disappear once you’re in the water.
