What’s undercover matters most when it comes to comfort, and our bamboo sport trunks have legions of fans – not just for their incredible next-to-skin comfort, but also for their sleek form-fitting cut. Made in our soft, smooth and stretchily supportive 200gsm jersey, the fitted sports trunks have a longer fitted leg to prevent ‘ride up’, a supportive front pouch with fly/keyhole feature, and a soft jacquard-woven elasticated BAM waistband for a secure yet comfortable fit. Put them through their paces – these are true ‘performance pants’.

  • Sleek and supportive fit
  • Breathable comfort and ease of movement
  • Front pouch with fly/keyhole feature
  • Ideal underwear for sports and exercise
  • Softly elasticated jacquard BAM waistband

Supremely soft, smooth and comfortable.
Imagine cotton T-shirt fabric only softer, smoother and with all the temperature controlling, moisture managing benefits of bamboo. There’s nothing better for next-to-skin comfort at any time of year.
