We fight tested the new Under Armour Threadborne Siro. Here’s what we learned.
The “Ber months” are clearly over and the summer heat is slowly taking over the Philippines. Training outside or in an enclosed space means that you’ll sweat buckets before your warm-up even ends. And in this kind of heat, it’s important that your gear keeps you comfortable without compromising performance.
The new Under Armour (UA) Threadborne Siro shirt hopes to help you achieve that. “Threadborne Siro fabric is built to eliminate distraction. We’ve engineered it to keep the ideal distance between fabric and athlete, so it won’t cling when wet and dries incredibly fast,” it reads on UA’s product description.
It boasts great stretch and soft touch, plus sweat-wicking ability. The goal is to keep you from feeling restricted and prevent chaffing. It’s marketed to be great for running, but we like punching stuff rather than running, so we took the UA Threadborne to the boxing gym.
No doubt, the fabric was comfortable and non-restrictive. Even as the sweat poured on, the fabric didn’t cling on to the skin.
We wouldn’t recommend this for no-gi grappling: rashguards are still ideal for that, plus you’d probably overstretch this shirt while grappling. But UA Threadborne is comfortable enough for your boxing or Muay Thai sessions, even in Philippine summer heat.
UA Threadborne sells for Php1,595 and is available in all Under Armour branches in the Philippines. You can also order your UA items online through underarmour.com.ph.
