Hiking and Lyme Disease
Last year, I switched to wearing long pants for all of my day hiking and backpacking trips to lower my risk of Lymes disease and Rocky Mountain Spotted Fever. I have an alarming number of friends who’ve contracted Lymes at least once, and it’s something to be avoided.
But the problem with wearing long pants is that you sweat a lot more in the crotch and between your legs, which can quickly lead to thigh chafing or diaper rash (monkey butt), unless you actively manage the issue. You can do this by finding long pants that have good ventilation like Railrider’s Eco-Mesh hiking pants and/or by finding underwear that is effective at wicking sweat away from your body. A third approach is to proactively smear Bodyglide or zinc oxide between your thighs and cheeks to reduce the likelihood of skin irritation. I often use all three of these strategies at once.
The amount of sweat your body produces will depend on the season of the year, weather conditions, what you are wearing, what you are carrying, and your level of exertion, meaning that no one solution will address every situation you find yourself in.
For example, for 3 season hiking and backpacking, I find that Ex Officio mesh briefs are adequate to prevent thigh chafing, although sometimes an application of Bodyglide is required. In winter, Under Armour Compression Shorts (above) are very effective at wicking moisture away from my sensitive parts. However, if I’m wearing a backpack, it will act as a vapor barrier and cause a lot of sweat to drip down my back. Under these circumstances it’s sometimes useful to apply zinc oxide pre-emptively.
As usual, figuring out what works took a lot of experimentation and a certain amount of skin irritation. Along the way, I tried Ex Officio Boxer Shorts but decided they don’t breathe well enough and like Patagonia Classic Boxers, they chafe when they get saturated. In addition I tried REI MTS boxers which feel great when they are dry, but cease to work when they get soaked with sweat under rain pants. None of the boxers I tried, dried very well at night, either.
In winter, I tried wearing Capiline 1 long underwear alone under a hard shell layer, but decided I needed a little more support, and tried the Under Armour compression shorts as a base layer. I came across this system almost by chance, but it is extremely effective because the compression shorts provide good leg insulation and they never feel wet under my long underwear. This is particularly useful on multi-day trips when I ah, wear the same pair of underwear for a few days in a row.
