MAGIC Prime Surf Head Cap Size: M New, purchased in Fall 2022, never used! Only tried on indoors. I usually wear caps and hats with a size of 59cm, but this fits perfectly when I tried it on. 【High Waterproofing】 This Prime cap uses rubber material, providing excellent waterproofing. Perfect for activities in the ocean or near water. 【Comfortable Fit】 Fleece material is used on the inside, providing a good feel against the skin and comfort for long periods of wear. The size can also be adjusted with a drawcord. - Brand: Prime - Color: Black/Green - Material: Rubber - Inner Material: Fleece - Design: Hooded - Adjustment: With drawcord
