The layer worn beneath a neoprene garment designed for aquatic activities serves several purposes. This underlayer, typically made of materials like rashguards, thermal underlayers, or specialized wetsuit liners, provides a barrier between the skin and the wetsuit itself. For instance, a diver might choose a thin rashguard in warm waters to prevent chafing, while a cold-water surfer may opt for a thermal layer to enhance insulation.
Its value extends beyond mere comfort. A suitable base layer can significantly improve the wetsuit’s performance by facilitating easier donning and doffing, reducing friction and subsequent skin irritation, and providing an additional level of warmth. Historically, individuals participating in watersports often wore simple cotton garments underneath their wetsuits, which proved ineffective due to moisture retention and lack of thermal protection. Modern materials offer superior breathability, quick-drying properties, and insulation, addressing these earlier shortcomings.
