The Kepler Boxers are made from corespun Merino wool for extra durability and comfort. Corespun Merino is made by wrapping a nylon and spandex thread with Merino fibres. This clever corespun fabric has all the benefits of standard Merino, but gives your boxers a better fit, helps them to keep their shape and extends their life. We only use super soft ultrafine Merino wool (17.5 microns) from certified non-mulesing farms.

There's no point covering yourself in technical outdoor gear if your cotton undies are going to get all damp and clammy. Merino wool is highly breathable, transporting your body’s moisture away from the skin to keep your nether regions comfortable underneath your walking trousers or running tights.

As an ‘active fibre’, Merino responds to temperature changes too. It controls the rate of evaporation to keep your bottom toasty in winter and cool in the height of summer. The Kepler Boxers use an active cut with flat-lock seams and a high, low-profile waistband to fit comfortably underneath various layers.

Merino wool is also naturally odour resistant. This means you get more uses out of your pants before consigning them to the wash bin. It also makes them ideal for multi-day backpacking trips - kinder on the planet and anyone you’re sharing a tent with!
