 We had zero. We were out there two nights in a row all night. So that stuff's really nice. And if you don't want to pay for that, you can spray some permethrin on. The Sitka has some extra features, though, like the built-in gaiters in the pants so the ticks can't crawl up your legs, stuff like that. Super slick. But, yeah, thermosels, permethrin, all that stuff, it's important. It's a comfort thing so you're not getting chased off the water by bugs, but it's also a health thing. Ticks are obviously scary with Lyme disease.
