I recently used the Hydra Arm Pads and Knee pads at the NXL Mid-Atlantic Open. I wasn't playing this event, however I was a photographer on the sidelines for the long days... and now I get why players praise these pads. The constant kneeling, getting up, and moving around took a toll on me the first day, and decided to swing by the Hydra tent to check out the pads. JD went over the ins and outs and the R&D that went into the creation of the pads with me. What impressed me most was how extremely comfortable they were—both the knee and elbow pads were insanely comfy they didn't slip out of place while I was constantly moving around. Bonus point for not feeling too hot or feel uncomfortable wearing them all day. They worked exactly as designed. The compression truly helped circulate blood around my legs, keeping them from feeling as fatigued. They made a huge difference for me as a photographer. Without them, I'm not sure I would've managed the full day. I love them and plan on using them moving forward. Highly recommended.
