Why We Love 'Em

Micro-Brushed French terry

So you get an ultra-soft feel (that doesn’t fade in the wash).

Streamlined Fit

So you can wear them anywhere.

Perfect Stretch + Recovery

So they’re always comfortable, but never saggy.

Back-Ribbed Ankle Cuffs

So they maintain their shape at the hem.

Comfy hat

This is a great hat to wear during the summer months when hiking. Very breathable and does a good job of protecting your eyes from the sun

Reviewed on See Mack Weldon on Junip (opens in a new tab)

Does this hat run large?

The crown sits deeper than typical baseball caps, so if you have an average to smaller head, you may need to tighten the adjustable strap significantly. The circumference adjusts via the back strap, but the depth of the crown itself doesn't change. It is designed with extra coverage that some runners prefer for sun protection, while others find excessive.

Will this hat stay on during running or high-intensity workouts?

Yes, the adjustable fit and quick-dry mesh sweatband keep it locked in place during movement, and customers report it performs equally well across running, boxing, tennis, and HIIT without shifting. The lightweight construction means you barely notice it’s there.

How do I care for this hat?

Machine wash it on a gentle cycle. The quick-dry mesh sweatband and laser-cut ventilation zones are designed to hold up to regular washing. Air dry to maintain the shape of the crown.

Is this hat good for hot weather and sweating?

The quick-dry mesh sweatband absorbs sweat without holding moisture, and the laser-cut ventilation zones allow airflow across your head. It is designed to dry fast whether you're running a 5K or doing outdoor training in heat.
