Keep it simple. Keep it Knobby. Explore men’s solid colour underwear for a drawer that lets the colour do the talking. Choose from the available trunks and long leg styles, check the fabric and fit, and find the plain undies you’ll reach for on repeat.

Men’s Plain Underwear, With Colour in the Mix

A plain pair doesn’t have to mean a drawer full of the same shade. Knobby’s men’s solid colour underwear gives you a choice of colours without an all-over graphic print. Go for a familiar favourite or mix a few different shades into your weekly rotation.

Start with the colours above, then choose the cut that suits you. This collection includes trunks and long leg underwear, so you can compare the available options before checking each product’s material and size guide.

Choose Your Cut, Then Your Colour

Colour is the easy part. For fit, think about the leg coverage you prefer and use the product’s size guide to check your measurements. Read the material details too: a solid colour describes the design, while the fabric and construction depend on the pair you choose.

Explore our men’s trunks to see more everyday options, or browse men’s long leg underwear for extra leg coverage. Planning a bigger top-up? Take a look at our men’s underwear packs.
