Running hat vs training hat: what actually changes?
Same category on the surface, two different engineering priorities underneath.

Running hats and training hats live in the same aisle, but they solve two different problems. A running hat is trying to stay out of your way for 60+ minutes of steady output. A training hat is trying to hold structure through fast, varied movement in a hotter environment.
Profile and weight
A running cap should be light and stay out of your peripheral vision on the road. A training cap can carry more crown structure. The APEX Hydro is built to do both well: structured enough to hold its shape, ventilated enough to keep air moving.
The structured crown helps the cap hold shape through direction changes and grabs, while laser-cut perforation keeps air moving.
Ventilation strategy
Runners generate steady heat over long durations; training generates spikier heat in shorter bursts. Laser-cut perforation and structured side panels on the APEX Hydro handle both.
Closure
Runners benefit from an adjustable rear closure that fits without pressure points across a long session. Training benefits from a locked-in structured fit that doesn't shift during dynamic movement.
Which do you actually need?
If you split your time between road miles and gym sessions, one cap covers both: the APEX Hydro.
