Men's underwear
No one sees it, but it shapes how the whole day feels. Men's underwear should sit securely, breathe well & disappear under the rest of the outfit. JACK & JONES offers boxers, trunks and briefs in cotton, modal and comfortable blends for guys who want a dependable base.
Comfortable, breathable & made for daily wear
A strong waistband should hold without digging in. The fabric needs to breathe and the cut must stay in place when you move. When fit, fabric and finish work together, men stop noticing the layer altogether.
Briefs, boxers & trunks
Briefs – close fit with minimal fabric
Boxers – longer leg with a relaxed feel, almost like shorts
Trunks – shorter than boxers with a supportive leg
Try more than one cut to find the level of coverage and support that fits your routine.
Men's underwear at JACK & JONES
Explore classic boxers, trunks and briefs in black, white, grey, blue and subtle prints. Cotton feels familiar and breathable, while modal blends feel smooth and light. Guys can choose clean basics or a little more character.
Which material works best?
Cotton is a reliable everyday choice. Modal has a softer, more fluid feel. Stretch in the blend can help during active days or under slim trousers. Check the seams and waistband, because these small details shape comfort and durability.
Multipacks for men
Multipacks build a practical weekly rotation and keep the drawer consistent. Choose black, white and grey basics or mixed packs with blue tones and understated patterns. Once the fit is right, buying several makes mornings easier.
From everyday wear to sport
For work, clean trunks in darker colours stay discreet. For sport, choose a close supportive fit with stretch. For long days in slim trousers, a longer leg can help prevent riding up. The right men's underwear is the pair you forget you are wearing after two hours.
