Thank you for viewing. This is an adjustable hood from World Dive, with a Velcro closure at the neck. I purchased it used, so the number of times it was used before is unknown. The surface and Velcro areas have little wear and tear, so it can still be used for a long time. It was too tight for me, as I have a large head, so I only stored it after purchase. I was told it was equivalent to a size M when I bought it. For reference, my head circumference is 57.5cm, and I have a round face. The thickness is 3-3.5mm, and the inside (orange side) is jersey material. There are creases from storage, but it won't be a problem when worn. Returns are not accepted, so please consider this item, understanding that it is a used item stored at home. It will be folded and shipped in simple packaging. [Brand] World Dive [Condition] Has some scratches and dirt It's very well-made, so I hope someone who can use it will take it. I will lower the price at my own timing.
