Thank you for viewing. This is a Callaway 4-way rainwear shirt. It has multiple functions such as waterproof, breathable, windproof, and stretch, but the waterproof function is slightly reduced, so I think it would be best used as a windbreaker. The inside is mesh, and the sleeves and hem can be removed. This is a used item, so please understand that it is non-returnable and non-refundable. Please refrain from purchasing if you are sensitive to the condition of used items. The condition is as shown in the photos. Thank you.
