How to use: Just put on this tank top like you would with any other shirt. It's great for outdoor activities such as hunting and hiking. Wear it comfortably during your all - day adventures. Notes: Make sure to refer to the sizing guide in the photos to choose the right size. Maintenance: Thanks to the anti - microbial finish, you don't need to wash it as often as regular tops. But when you do wash it, use a gentle cycle with mild detergent to keep its performance and quality intact.
