Product Care

No Fly Zone Product Care

Machine wash cold with like colors.  Use non-chlorine bleach.  Tumble dry low.  Remove promptly from dryer. Dryer sheet  not recommended.  Low iron.

Do not dry clean garment as dry cleaning can diminish No Fly Zone performance. 70+ washings until NFZ starts to deteriorate.



  • 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.

  • In a select group of sportswear and hats, we've combined our COR3™ technology with the insect repellent technology from Burlington® Labs - No Fly Zone™. No Fly Zone™ is a permethrin-based insect repellent (odorless, water-based and biodegradable) tha offers excellent protection from multiple species of crawling and flying insect. This package of COR3 and No Fly Zone technologies provides you with maximum sun protection (UPF 50), insect repellent, moisture-management and anti-odor performance in sportswear made specifically for anglers. Burlington® Labs utilizes a patented process, one of the industry's safest, to bind the insect repellent to the fabric. The consistent application of the repellent to the fabric also ensures unprecedented performance and durability.

  • 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 50 will allow only 1/50th 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.

BugBlocker Shirt Review by MC
Hands down the most comfortable and best looking piece of fishing clothing I have ever worn. The shirt keeps you cool, and it truly keeps the bugs off..from horseflies to mosquitoes to yellow jackets. Big props to Simms for eliminating the need to drench myself in DEET.
