Going camping or hiking any time soon?
Do you like out doors in general?
Need to write or take notes under tough weather conditions, especially when it rains.
Check this pen that writes through water, grease, and mud without clumping or smearing.
It writes in temperatures from -30F to 250F, under water (up to 35 ft), and any angle.
Need a notebook that you can use in all weather conditions as well? Check this all-weather notebook, that has weather-proof paper and that goes well with the pen.
