SITKA GUARD LS SHIRT

The Sitka Guard LS (Long Sleeve) Shirt is a premium, high-performance warm-weather operational matrix engineered for backcountry operators and precision anglers requiring rapid environmental adaptation in intense solar and high-insect environments. Moving away from uncalibrated, heavy button-downs or standard synthetic shirts that trap sticky humidity, cling to sweaty skin, and offer zero protection against biting pests, this advanced technical garment organizes your upper-body workspace in an ultralight, highly breathable layout built for intense heat and streamlined physical clarity.

Key Features:

• Bite-Resistant Stretch Woven Core: Form-engineered with an ultra-lightweight, high-gauge stretch woven polyester textile to deliver an uncompromised balance of unrestricted casting or poling mobility and a physical mechanical barrier against biting insects.
• Insect Shield® Technology Matrix: Fabricated with long-lasting Insect Shield® treatment bonded directly into the textile fibers to amplify field protection, filtering out mosquitoes, ticks, ants, flies, chiggers, and midges without the need for greasy, chemical topical sprays.
• Polygiene® and Solar Shield Geometry: Outfitted with an integrated UPF rating to block harsh solar radiation, working alongside permanent Polygiene® Odor Control Technology to actively neutralize sweat bacteria and eliminate multi-day scent vulnerabilities and technical lag.
