Cooltan Men's Tan Through Swim Trunks allow you to get an allover even tan right through the fabric! Featuring an elastic waist, drawstring, and linerless interior. The mid thigh swim trunks hit a few inches above the knee for a classic swim short look. The fabric is quick drying, making it great for travel! Made in USA. ABOUT THE FABRIC: The unique patent-pending fabric used in Cooltan tan-through swimwear is made with a special knitting technology that creates millions of tiny pores in the fabric. These pores allow approximately half of the sun's light to pass through to approximately the same degree as a medium level sunscreen. They are more comfortable than a regular suit because they allow your skin to breathe. Also, because of the suit's construction, the fabric will dry faster if you decide to take a dip in the pool while wearing it. Cooltan swimsuits dry quickly both when you wear them and after you wash them, making them extra comfortable, and a great travel suit! You will tan at the rate that you normally tan based on your skins melanin content, and that for an even, all over tan we suggest to use an SPF lotion of 6 to 10 (or higher as needed) on skin which is not covered by the suit. We also recommend using sunscreen with an SPF 30 for a more even, all over tan. Cooltan suits are not see through when worn. However, the fabric is quite thin due to the tiny holes in the fabric which allow the sun to pass through the fabric and allow you to tan, and from person to person the level of transparency may vary. The fabric works like a medium level sunscreen, and it is possible to burn though this level of sun protection. Please use caution in the sun. Please moderate your initial exposures to the sun until you have a base tan that will help protect you further from sunburn. Remember, vacations should be fun! All Cooltan swimsuit fabric, as well as the suits themselves are made in the USA! Men's Cooltan suits are true to size. Please order the size you normally wear in shorts/pants. The fabric is soft and smooth, in addition, the porous nature of the fabric allows your skin to breathe, which keeps you cool by letting perspiration evaporate quickly. The fabric used in Cooltan suits is has an exceptionally high resistance to pool chemicals and ocean salt. They are NOT affected by pool chlorine or ocean salt. In addition, the pores in the fabric prevent water from building up inside the suit, which is an advantage for competitive swimmers. Cooltan Tan-Through suits are fully machine washable, but DO NOT machine dry them. Hang dry them or lay them flat to dry.
