UltrAspire Running Vest Technology Update: The Max O2 Strap

Anyone who runs with a hydration vest knows the importance of being able to move freely while wearing it. If you have a pack on, chances are pretty high that you’re on a long run. When it comes to long runs, comfort is key, because even the smallest issues build up and can become bigger issues as your run progresses.

ultraspire_alpha_20_vest_1Most hydration packs and vests come with an adjustable strap of some sort in the front. Various belts and clips work together to fasten your vest in the front, enabling you to get the vest on and off with ease. The issue with many traditional front fasteners? They can cause problems. Clips can cause irritation as you run, rubbing up and down if the pack doesn’t fit just perfectly. And another issue is getting it to fit just perfectly, as your chest’s volume fluctuates throughout your run… even from breath to breath. So how can you keep your vest securely fastened with just the right fit, while also ensuring that there is enough room for you to breathe and adjust throughout your run?

The Max O2 Sternum Strap System

ultraspire_alpha_20_vest_3UltrAspire has come up with a vest closure that helps solve these issues. The Max O2 Sternum Strap is an innovative solution that UltrAspire is using on all of their new running vests. The elastic bands provide connection in two places, allowing two points of adjustment instead of just one for an accurate fit. Because of this design, you can adjust the straps with one hand, which makes on-the-run adjustment a cinch. And the genius part about these elastic straps is that they allow for a little bit of stretch as you run – just enough to account for your breath and to allow you a comfortable range of motion and chest volume variability while also remaining secure around your body.
