A thermal long john keeps your core warm while leaving your arms free for steering and handling gear. It sits comfortably under a spray top on colder days on the water. The neoprene keeps a thin layer of warmth trapped against your skin once you get wet. Consider these details:
- Smooth seams to prevent chafing during movement
- Flexible side panels for easier crouching
- Reinforced lower sections for sitting on non-skid surfaces
- Snug ankle cuffs to stop water flushing inside
