The CoolBase Short – No Roll. No Sweat. No Lines.

Most of what you wear was built to last, not to breathe. It holds heat in, holds sweat against your skin, and by the end of a long day you feel every hour of it.

The CoolBase Short is the layer underneath that fixes that. FlatWick™ fabric pulls sweat off your skin so it can dry, the leg bands stay exactly where you put them, and the laser-cut edges disappear under anything you wear.

No powders to reapply. No shorts rolling down by lunch. Just a layer you stop thinking about.

Wear it on its own. The breathable cotton gusset means you don't need underwear underneath.

Get the right size. Measure your waist and the widest part of your hips, then match to our size chart. Between sizes? Size up.

Care: Machine wash cold, gentle cycle, ideally in a mesh bag. Hang or lay flat to dry. No fabric softener — it coats the fibres and reduces wicking.

FlatWick™ fabric — flat-profile nylon yarn that pulls sweat away from your skin and spreads it out to dry fast

No-roll leg bands — extended, grip-lined bands that stay put through walking, bending and sitting

Laser-cut edges — lie completely flat, no visible lines or seams

Built-in cotton gusset — breathable, so no underwear needed

Seamless knit — no side seams to rub or chafe

Friction-free finish — glides under clothing instead of catching or bunching

Won't wearing an extra layer make me hotter?

It's the opposite. Cotton underwear and most clothing fabrics hold sweat against your skin. FlatWick™ fabric moves it away so it can evaporate — which is what keeps you feeling cool.

Do I wear underwear underneath?

You don't need to. The breathable cotton gusset is designed to be worn on its own.

Will they roll down or ride up?

The grip-lined leg bands are built specifically to prevent that. If they don't stay put for you, you're covered by our guarantee.

Will they show under my clothes?

The laser-cut edges lie flat against your skin, so there are no lines under fitted pants, skirts or dresses.

Is this shapewear?

No. There's no compression or shaping — it's a lightweight, breathable base layer designed for comfort.

What size should I get?

Use our size chart with your waist and hip measurements. If you're between sizes, size up. Wrong fit? We'll exchange it for free.

How do they hold up in the wash?

Wash cold and hang dry and they'll keep their shape. Skip fabric softener to keep the wicking working.
