Description
When the brief is simple - comfortable, reliable, well-made underwear in a colourway that works with everything - the men's Nike Dri-FIT Essential Cotton Stretch Trunk 3-Pack delivers exactly that. Built from 95% cotton and 5% elastane, the natural softness of the cotton blend is the first thing that separates this from a synthetic-only alternative, while the elastane content provides the four-way stretch needed for complete freedom of movement at every point in the day. Dri-FIT technology manages moisture efficiently throughout, and the contour pouch with flat-lock seams provides support and a no-chafe wear in all the right places. Wide banded leg hems sit securely without constricting, and a branded elastic Nike waistband closes out the design. 95% cotton, 5% elastane construction with Dri-FIT moisture management Contour pouch with flat-lock seams for all-day support and comfort Wide banded leg hems to prevent ride-up Branded elastic Nike waistband with 4-way stretch T 3 Pairs

How to measure your foot
- Place a sheet of paper on a hard floor against a wall.
- Stand with your heel touching the wall.
- Mark the tip of your longest toe on the paper.
- Measure the distance in centimetres from the wall to the mark.
- Compare against the relevant brand guide above, since exact sizing varies slightly between Nike, adidas, ASICS and New Balance.
