These are the lightweight sleeves made from fine 1.2-mm netting that shields the skin from mosquitoes without the use of harmful and malodorous chemicals. Worn over regular clothing, the sleeves protect against insect-borne illnesses such as Zika and West Nile virus, as well as the discomfort of itchy welts. Only available from Hammacher Schlemmer, the sleeves stay in place with elastic collars and provide monkey paw openings for the hands. While standard insect repellents must be reapplied after several hours, the sleeves provide continuous, nontoxic, and environmentally friendly coverage without DEET or fragrances. The machine-washable polyester stretches to allow freedom of movement while engaging in outdoor pursuits, and is breathable so it won’t trap heat, helping you stay cool even in tropical climates. For best protection, a loose fit is recommended. Olive. Unisex size S/M or L/XL.
