WindRiver Tick & Mosquito Repellent Clothing Frequently Asked Questions


What is WindRiver tick and mosquito repellent clothing?
Exactly that! Exclusive to Mark’s, this product line consists of men’s and women’s apparel and accessories that repels ticks and mosquitoes (yes, such a thing exists).

Science, Technology and Safety

What makes the clothing repel ticks and mosquitoes?
The apparel and accessories are treated with a bonding application of permethrin to repel ticks and mosquitoes from the areas of the body covered by the treated garments. Fun fact: everyone and their relationship to mosquitoes is unique based on the carbon dioxide their body gives off.
What is permethrin?
Permethrin (pr·meh·thruhn) is a broad spectrum synthetic pyrethroid insecticide that is bound to the fabric to repel ticks and mosquitoes.
Do I still need to wear insect repellent with the clothing?
You are encouraged to wear insect repellent in addition to tick and mosquito repellent clothing.


Will the product lose its effectiveness when it gets wet?
No. We know the unpredictable weather conditions in Canada and encourage everyone to put our gear to the test. These products will remain effective up to 70 washings through a regular wash/dry cycle.
Can I wash/dry it normally with other clothing?
These products should be washed separately from other garments but can be washed normally. Please see specific garment tags for washing instructions.
Is the product still effective if you wear a jacket overtop?
Yes, but the effectiveness will be limited if the jacket is untreated. Thankfully, this product line includes jackets, shirts, pants, shorts, hats and bandanas for men and women.
Do the garments have UV protection?
Yes, but each garment provides a different level of protection based on colour and the UV application. Please see individual garment tag for UV protection level.
Are there plans to incorporate the technology into industrial apparel?
Yes. We’ve applied this technology to polyester and are working towards approval for cotton and other industrial-focused fabrics – stay tuned!
