We’ve cracked the performance code with our Quantum line of wetsuits, ending the era in which high performance and flexibility equate to a compromise in durability. Our game-changing approach starts with quality materials like limestone-based neoprene and specially developed linings with stretch zones in high-movement areas. The upper-body panels of this cool-water, long-sleeved shorty are internally reinforced with our flexible THERMO insulation to prevent windchill in exposed areas. The seams of the Quantum Chest-Zip Long-Sleeved Shorty 2/2MM F/L suit are flatlock stitched for extra strength, and the “easy-in” chest-zip design prevents water from flushing through the soft-feel, compression-cut collar. The Quantum will change your expectation of what a wetsuit can be.
