The one I train in most. Every session.
FROM THE FOUNDER
Hey, Sonny here.
The Onyx is the version of the Aero I reach for most. Black, clean, goes with anything. When I'm not overthinking what to wear to train, I'm wearing this.
Same performance build as the rest of the Aero line — high neckline for barbell work, split hem for deep squats, 4-way stretch that moves with you. But in a colour that works whether you're in the gym, walking the dog, or heading to a session after work.
This is the vest I've worn to more training sessions than I can count. If you're buying one vest from Send It, start here.
