These are 2mm thick wetsuit pants. The surface uses a highly durable nylon fabric, and the middle is made of neoprene material, offering excellent warmth, elasticity, and durability. Even when submerged, they can prevent body temperature loss and protect against scrapes from jellyfish and other marine life. With UPF50+, they can block 98% of UV rays. Flatlock stitching is used, making the seams that contact the body flat. The elastic thread maintains the material's stretchability without compromising it, thus preserving mobility. The drawstring located inside the waistband of the wetsuit pants can be adjusted steplessly, allowing for size adjustment according to the wearer's waist circumference.
