Fabric percentages tell you how a boxer brief is likely to feel and move. Pure cotton and cotton blended with a small amount of elastane serve different needs.
What cotton brings
Cotton is familiar, soft and comfortable for everyday wear. It gives underwear a natural hand feel and helps the fabric stay pleasant against the skin.
Why add elastane?
Elastane gives fabric stretch and recovery. In a close-fitting boxer brief, that stretch helps the garment move with you and return toward its original shape after wear.
How the BENEATH blend works
BENEATH boxer briefs use 95% cotton and 5% elastane. The cotton provides the everyday feel, while the elastane supports a close fit without turning the boxer into compression wear.
Which should you choose?
Choose pure cotton if you prefer a looser, less structured garment. Choose cotton-elastane when you want a closer boxer-brief fit that follows movement.
Fit still matters
Fabric cannot compensate for the wrong size. Measure where the waistband sits and use our boxer size guide. If you are between sizes and prefer more room, choose the larger size.
