Cold Water Performance Diving Suit Project
This project explores the design of a performance-driven diving suit system for extreme cold-water environments, specifically Silfra, Iceland. The objective was to understand how textile systems influence thermal regulation, mobility, and overall human performance under high-risk conditions.
Through research in human physiology and environmental constraints, our team developed a layered clothing system incorporating polyester base layers for moisture management, neoprene for insulation and flexibility, and wool for additional thermal retention. Material selection was guided by performance requirements including heat retention, durability, and wearer mobility.
This project emphasizes the relationship between textile materials, garment construction, and end-use performance, demonstrating how design decisions directly impact safety, comfort, and functionality in demanding environments.
Design Constraints
-
Extreme cold-water conditions (3°C) requiring high thermal insulation
-
Need to maintain core body temperature during prolonged exposure
-
Balancing insulation with mobility and range of motion
-
Material durability under pressure and repeated use
Future Development & Testing
-
If continued, this project would focus on validating the suit's performance through controlled testing and material optimization.
-
Conduct thermal and wear testing in a controlled laboratory environment (e.g., cold water immersion or simulation lab)
-
Evaluate effectiveness of 10 mm neoprene thickness for insulation vs. mobility
-
Test alternative material thicknesses and layered systems to optimize performance
-
Assess long-duration wear for comfort, flexibility, and physiological response
-
Refine garment fit and construction based on performance data
