Case Study

u-zip-it™ u-shaped zipper

Designed for Comfort and Unassisted Donning

The challenge

Traditional dry suit entry systems often rely on zipper placements that can restrict movement, create discomfort during extended wear, and require assistance to fully close or remove the suit. These limitations can become especially frustrating during long missions when users need flexibility,
comfort, and the ability to manage the suit independently

Operational context

  • Search and Rescue operations
  • Offshore energy environments
  • Aviation survival applications
  • Maritime and military mission

The switlik solution

Switlik developed the patented U-ZIP-IT™ U-Shaped Zipper to improve the overall dry suit experience. Unlike traditional zipper configurations, the low-slung U-shaped design allows for easier donning, unassisted zipper closure, enhanced comfort, and unrestricted movement. The innovative placement minimizes interference with the wearer's natural range of motion while increasing usability throughout extended missions.

Key advantages

Unassisted Suit Entry
The low-profile U-shaped zipper allows users to don and secure the suit without assistance.
Enhanced Comfort & Mobility
Strategically positioned zipper placement minimizes interference and allows for a full range of motion.
Comfort During Downtime
The upper portion of the suit can be lowered during periods of inactivity, helping reduce heat buildup and improve comfort.
Simplified Restroom Access
Users can open the lower section of the suit without completely removing the upper portion, making extended wear more practical.
