Every strength athlete needs a few specific devices in his gym bag for those heavy days. No, not tampons for THOSE heavy days, but bar bending, joint smunching days. One of my favorite wrap companies is Inzer. They have been doing it a super long time and have perfected several different types based on the need and type of exercise being performed.
But in my gym bag, I rely on APT Pro Lifting Gear for my wraps and straps. The Blue APT Wrist Wraps are available in lengths from 12" all the way up to 50"! These can be tension adjusted like any other kind of wrap and provide years of quality service with a Velcro closure. The APT Blue Knee Wraps are the old school approach to securing them once wrapped, and that's tucking under one of the last wraps. Some manufactures use velcro closures and in my experience, the Velcro fails far too soon and renders it useless. The knee wraps come in lengths from 2 meters to 5 meters! That's a ton of wrapping or thems' some big ol' tree trunks that are being wrapped???
