 Why do gamers wear arm sleeves? This is mainly due to having a consistent temperature for the arm you play on. So if it's a cold room for example, having a consistent temperature will be less distracting as well as that's annoying. We all have that feeling when you're playing in a winter time and you just feel like you can't aim. It's mainly due to your hand freezing and bad circulation, leading it to have a slower reaction time as well as harder movements. Arm sleeves are also great for both mouse pads and arm sleeves should be a soft material unlike a patterned mouse pad. Some players report a burning sensation when they do a fast wipe on a mouse pad and I myself don't have that issue but many gamers in the east were seen play for long hours just scratching their forearms on a mouse pad so I guess it could be appealing to them. Finally, an arm sleeve reduces friction on your mouse pad, leading to a quicker and faster glide. This could definitely be helpful if you have a lower sense as it would feel a lot more satisfying to glide your whole forearm on a mouse pad. So on and all, should you buy one? Well they're pretty cheap and the only reason I would consider it is if you live in a cold climate or if you play on a mouse pad and have a really low sense. Other than that, it's not that big of an upgrade than a new mouse or a new keyboard. Of course it won't turn you into a shout out but thanks for watching and have a good day.
