A GAME-CHANGING, BACK-ZIP SHORT-SLEEVED WETSUIT THAT IS BUILT TO LAST 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 short-sleeved, cool-water full suit are internally reinforced with our flexible THERMO insulation and a wind-resistant mesh-skin on the chest and back to prevent windchill in exposed areas. The seams of the Quantum Back-Zip Short-Sleeved 2/2MM F/L suit are flatlock stitched for extra strength, and the back-zip design allows for easy entry and exit so you won't waste any energy wrestling with your suit and can save it for the lineup. The Quantum will change your expectation of what a wetsuit can be. split 80% Neoprene, 15% Nylon, 5% Polyester split SIZING: XS, S, ST, MS, M, MT, LS, L, LT, XLS, XL, XLT, XXL, XXLS split Features FLX_THERMO lining Flatlocked Wind resistant meshskin chest and back Adjustable lycra bound collar YYK zip with metal slider
