"Jacket" - what is it, definition of the term
A short, tailored outerwear garment that covers the torso and arms, usually fastened with buttons, a zipper, or a snap, and designed to supply thermal insulation or protection against wind, rain, or other environmental conditions.
Detailed information
The outerwear piece designed for outdoor activity incorporates several protective measures against ectoparasites such as ticks, insects, lice, and fleas. Fabric selection prioritizes tightly woven fibers—nylon, polyester, or ripstop cotton—whose pore size prevents arthropods from penetrating the material. In addition, manufacturers often apply insect‑repellent finishes containing permethrin or pyrethroids; these chemicals remain effective after multiple washes while posing minimal risk to the wearer when applied according to safety guidelines.
Key design elements that enhance pest resistance include:
- Integrated cuffs with elastic or Velcro closures that seal the wrist openings, limiting entry points.
- Adjustable storm flaps over front zippers, reducing gaps where crawling insects could slip through.
- High collar or stand‑up neck that can be fastened snugly against the chin, blocking attachment sites on the neck and shoulders.
- Reinforced seams sealed with heat‑taping or ultrasonic welding, eliminating needle‑size openings.
Maintenance practices preserve the protective qualities of the garment. Regular laundering at 30–40 °C removes accumulated debris and deactivates residual chemicals that may degrade over time. Re‑application of an approved repellent spray is recommended after every fifth wash or when the fabric shows signs of wear. Storage in a dry, sealed container prevents moisture‑induced mold, which could attract fleas or lice.
When selecting a pest‑resistant outer layer, consider the following criteria:
- Certified insect‑repellent treatment verified by an independent laboratory.
- Fabric weight and durability appropriate for the intended climate and terrain.
- Availability of replaceable inner liners for added comfort and easy cleaning.
- Compatibility with additional protective gear, such as gaiters or insect‑proof trousers.
By adhering to these specifications and care instructions, the garment provides reliable barrier protection, reducing the likelihood of arthropod bites and subsequent disease transmission during fieldwork or recreational pursuits.
