The Fourth Element X-Core Womens Sleeveless Vest Top, The sleeveless design of the vest minimizes impact on buoyancy and overall bulk especially in the shoulders and arms where freedom of movement is critical. The four-way stretch fabric combined with long body design ensures a snug fit, minimizing cold points. The additional chest panel helps to minimize the rush of cold air from the inlet valve and provides extra thermal protection in a key exposure area. The fast wicking fabric moves perspiration towards the outer surface, keeping the wearer drier and warmer. The physiological response to cold stress is to reduce blood flow to the periphery and look after the body core, where it can often just be a matter of time before cold becomes the limiting factor in the safety and enjoyment of a dive. X-Core provides extreme thermal protection to the core, enabling longer, more comfortable dives.
