Are these true to size?

Yes, the 18-Hour Jersey Short runs true to size. The cotton-modal blend has just enough stretch to move naturally without clinging, so you don't need to size up or down.

What's the fabric like? Is it actually as soft as it sounds?

The 18-Hour Jersey fabric is a cotton-modal blend designed to feel like pajamas, lightweight, breathable, and with no structure or restriction. You're getting the weight and softness that makes these feel less like shorts and more like comfortable loungewear.

Will these work for summer?

Yes. The lightweight, breathable cotton-modal blend is made for warm days and summer nights. The fabric breathes well enough that you won't overheat, and the minimal weight keeps them comfortable in heat.

How do I care for these?

Machine wash the 18-Hour Jersey Short in cold water. The cotton-modal blend is durable through regular washing and designed to maintain its softness and shape over time.

What's the inseam length?

The 18-Hour Jersey Short has a 9-inch inseam, designed for a classic shorts length that sits at the knee.
