Simms Fishing knows what men need for endurance on the water, and a new line of shirts made with brrr° cooling fabric deliver the goods.

The Simms Stone Cold Shirt with short sleeves is a button-up made with stretchy woven brrr° nylon/elastane fabric for complete freedom of movement and a cooling effect to keep you dry and comfortable on sweltering hot days. The Stone Cold Shirt is also available with long sleeves.

For buggy conditions, try the Simms Bugstopper Fishing Shirt made with stretch brrr° fabric and Insect Shield®️ technology. Insect Shield®️ has been registered to repel mosquitoes, ticks, ants, flies, chiggers, and midges (no-see-ums) and the active ingredient is so tightly bonded to the fabric fibers that it retains effective repellency throughout the lifetime of the product.

The Simms shirts are made with brrr° cooling fabric, which combines natural cooling minerals, active wicking, and rapid drying for a permanent cooling sensation that won’t ever wash out or fade. brrr° creates a Triple Chill Effect®️ that instantly and continuously draws heat and moisture away from the skin.

The shirts are machine washable and offer UPF 50+ sun protection to block harmful ultraviolet rays. They also feature two zip chest pockets to keep essentials handy and secure, while a built-in chamois keeps sunglasses streak-free.
