Which base layer is recommended for cold-water boating?

• A. Cotton base layers.
• B. Non-cotton base layers.
• C. Silk base layers.
• D. Denim base layers.

Answer: (B)

Non-cotton base layers are recommended because they manage moisture and warmth better in cold-water conditions. The goal of a base layer is to move sweat away from the skin and keep you warm, even if you get wet. Cotton does the opposite: it absorbs water, stays damp, and quickly loses its insulating value, making you colder and increasing heat loss if you’re splashed or fall in. Silk isn’t reliable for warmth once damp and isn’t as durable for boating needs. Denim also soaks up water and stays heavy, exacerbating heat loss. Non-cotton fabrics—synthetic wicks or merino wool—draw moisture away, dry faster, and keep insulation effective even when damp, which is crucial for staying warm and reducing hypothermia risk in cold-water boating.
