Made from durable neoprene with elastic fabric, this diving hood delivers long-lasting thermal protection and a comfortable fit. Key benefits Retains body heat: Azo-free neoprene improves insulation so you stay warmer for longer in cold water. Comfortable fit: Stretchy elastic fabric conforms to the head without pinching, reducing water flushing and discomfort. Durable and wear-resistant: High-elasticity neoprene resists abrasion and maintains shape through repeated use. Versatile protection: Covers head and ears to reduce heat loss and protect from wind and spray during water activities. Features and performance Material: Neoprene construction with azo-free treatment for improved heat preservation. Fit and comfort: Elastic fabric provides a snug, low-profile fit that works with common wetsuit collars and masks. Durability: High elasticity and wear resistance extend service life under regular diving, snorkeling, or water-sports use. Function: Designed to insulate the head, limit water exchange, and increase comfort in cool to cold water conditions. Compatibility and sizing guidance Intended for use with standard wetsuits and other neoprene gear; choose a size that matches your head circumference for best seal and comfort. If in doubt, refer to the seller’s sizing chart or measure head circumference at the forehead for an accurate fit. Practical use scenarios Cold-water scuba diving: Keeps the head and ears insulated during extended dives in lower temperatures. Snorkeling and freediving in cool conditions: Reduces heat loss and minimizes ear discomfort from cold water. Open-water training or winter water sports: Adds an extra layer of thermal protection for swimmers, triathletes, and paddlers. This diving hood combines insulation, stretch, and durability to improve comfort and thermal performance during aquatic activities.
