The bc stands for bell curve. the bc vests front and back bell curve paneling ensures your vest stays on even when the surfs going off. a vest that locks down in a heavy wave is not only warmer but also safer.

Most neoprene is petroleum-based. It's messy, it's hazardous - it goops up sea otters. Matuse's wetsuits are made from Yamamoto rubber, which is derived from 99.7% pure limestone. It is warmer (98% water impermeable) and lasts longer (titanium coated) than standard neoprene. It is also kinder to mother nature since it's made from limestone and does not come from petroleum. Yamamoto's Geoprene technology means thinner rubber is warmer rubber. It not only weighs less, it also allows athletes to focus on the right issues (like better surfing), and fuss less over the wrong ones (like being cold, uncomfortable - and performing like a wet noodle).

Features:

• Flat-stitched for warm conditions.
• All SCS is Titanium-coated Geoprene (preventing evaporative heat loss).
• Hydrasilk Nylon liner on inside.
• Piece called “BC” for the bell-curve panel on front and back. This locks the torso down in heavy surf.
• Short-loop in front for trunks.
• Pull String in back for custom waist fit.
