  • Products using the COR3™ Technology fabric finish have a UPF rating of 30 or greater, properties to minimize odor and outstanding wicking performance for important moisture management. The anti-odor finish helps control odors caused by a wide range of microorganisms (mold, mildew, algae, yeast) is compatible with virtually all fabrics. All of our performance cotton clothing utilizing COR3™ also feature COR3™ EZ. The "EZ" means easy care and indicates that garments featuring this treatment will travel well and resist wrinkles.
  • At Simms, sun protection is a critical component of our sportswear offering.  Through a combination of fabric construction, design and finish, we offer a wide range of clothing that features a minimum UPF of 30 (very good) up to UPF of 50 (excellent).  UPF stands for Ultraviolet Protection Factor and indicates how much of the sun's UV radiation is absorbed.  A fabric with a rating of 30 will allow only 1/30th of the sun's UV rays to pass through.  This means the fabric will reduce your skin's UV radiation exposure significantly.  All of our UPF finishes last the life of the garment, an industry standard of 30 washings.


Machine wash cold with like colors.  Use non-chlorine bleach.  Tumble dry low.  Low iron.
