The Insect Shield Women's Long Sleeve Tee is a lightweight, quick-dry top designed for outdoor activities where insect protection matters. Made from 100% microfiber polyester (4.7 oz), it provides all-day comfort in warm conditions while keeping bugs at bay.
The garment's defining feature is EPA-registered permethrin repellent bonded directly into the fabric fibers. This built-in protection repels mosquitoes, ticks, ants, flies, chiggers, and midges without the need for topical sprays or reapplication. The permethrin treatment is odorless and remains effective through normal home laundering; dry cleaning is not recommended. The shirt also offers UPF 30+ sun protection, making it a versatile layering piece for hiking, gardening, camping, or any outdoor pursuit.
