Swimrunners waterproof waist bag is easy to wear underneath the wetsuit and holds your mandatory equipment. Highly-durable PVC material with tight seams can perfectly keep items dry and protected from water. Through the translucent color, you can easily see your map or find your items. Swimrunners waterproof waist bag is IPX8 certified to 9 meter. The triple zip locks are held down by velcro which prevents water from seeping through the inside. Always make sure that you seal all the zip locks before using. The adjustable waist belt can be adjusted around your waist (appliable waistline: 81-114 cm).
