Even a small emergency helper can make a big difference. Just the timely use of the tick remover can prevent worse situations when you're in the wrong area. But of course, the First Aid Mini Set also covers the many small cuts and scrapes that you might get along the way. 420 HD nylon (100% nylon) is a classic 420 denier polyamide material and is unmatched in its uncompromising quality. It has proven itself in high-density (HD) form as a good base material that can be used flexibly. The 420 denier thread provides a high level of tear resistance. With a 4-fold PU coating, the material is equipped to be waterproof.
