In my line of work, I find myself out in the sun quite often. Couple this with the facts that I'm as white as a ghost and really, really hate applying sunscreen because of the grease factor, and I'm a prime candidate for a nasty sunburn. Luckily for me, the company I work for found SunX Sunscreen towelettes.
These easy-to-use towelettes supply the user with an SPF of 30 that holds up easily for ninety minutes. While that's great, what really sold me on this product is the fact that it's not greasy and holds up very well against sweat and water.
To apply the sunscreen, simply pass the towelette over any exposed body parts and you're covered for roughly two hours of hard work or play. I also suggest passing the towelette over parts of the body that aren't exposed as well. The packaging states that the SPF holds up for eighty minutes, but I find that it works a bit longer than that.
Protection from the sun is key. Wearing a wide-brimmed hat and long sleeves (if you can stand them in the heat) will only add to the protection provided by SunX Sunscreen towelettes. I highly recommend them to anyone in the telecommunications field, construction, farming or any other occupation that involves work outdoors.
