Calvin Klein Cotton Stretch Trunks, 3-Pack, Black/White/Grey Heather, Size M

For everyday dressing, these Calvin Klein trunks offer a close-fitting underwear option in a practical three-pack. The set includes black, white and grey heather pairs, giving you a choice of colours for your regular rotation.

Made from cotton stretch fabric, each pair combines 95% cotton with 5% elastane. The stretch blend supports a comfortable fit, while the mid-rise cut sits on the hips.

A classic elasticated waistband with Calvin Klein branding completes the minimalist design. Wear them for day-to-day comfort or when getting ready for sport, choose a simple everyday staple or a more fashion-led look without changing the practical trunk shape.

Highlights

The three-pack brings together three familiar colours in one set: black, white and grey heather. That makes it straightforward to rotate between pairs through the week, while keeping to a consistent style. The trunks are offered in size M.

The cotton-and-elastane blend combines a soft cotton feel with stretch. Their mid-rise design sits at the hips, and the branded elasticated waistband adds a distinctive detail without changing the clean, understated look. For shoppers choosing between basic underwear and a more visibly branded style, this set pairs a classic colour palette with Calvin Klein’s signature waistband.

The trunk cut is suited to everyday wear and sports, making the set useful across different parts of a regular routine. Reach for a pair under day-to-day clothing, or wear them as your base layer when changing for exercise. The three colours offer a little variety while retaining the same fabric blend and design.

Practical tips

The care instructions are simple: machine wash the trunks and tumble dry them. Follow the garment’s care label when laundering, and sort the colours as you normally would for a mixed-colour wardrobe. Keeping the three pairs together in your underwear drawer makes it easy to choose a fresh pair as part of your everyday routine.

Best use cases

These trunks suit anyone looking for a familiar mid-rise shape for regular wear, with stretch in the fabric for a comfortable feel. They can form part of an everyday underwear rotation, and the stated suitability for sports makes them a practical choice when getting dressed for activity as well. The black, white and grey heather options work for shoppers who prefer classic colours over a set built around bright or varied prints.

If your priority is a simple underwear staple, the cotton-stretch fabric, three-colour selection and easy machine-wash care make this set a straightforward fit for regular use. If you prefer underwear with a recognisable branded detail, the elasticated Calvin Klein waistband brings that into the design while keeping the overall look minimal.

Should you buy it?

It makes sense if you want three pairs of branded trunks for everyday wear, with a mid-rise fit, a cotton-stretch blend and a classic range of colours. The set also suits an active routine, so you can use the same comfortable trunk style for ordinary days and sports. Choose this Calvin Klein pack for a practical rotation of black, white and grey heather underwear in size M.
