Available only from Hammacher Schlemmer, this is the lightweight shirt made with a super-fine 1-1/4mm mesh material that shields the skin from mosquitoes, ticks, and other pests. Unlike repellents that use DEET or fragrances, this shirt helps inhibit insects and the illnesses they carry such as the Zika virus, West Nile virus, and Lyme disease without the use of chemicals. The breathable fabric does not trap heat. With fitted sleeve cuffs to keep insects out. Machine washable and dryable. Stretch fit. Grey. Unisex sizes S, M, L, XL, and XXL.
