CK One briefs, restocked for the week

What reviewers say

Questions and answers

Is the CK One Modern Brief true to size?

It fits most buyers at their usual size, but several owners say it runs small and suggest sizing up if you are between sizes or prefer a looser fit.

What is the fabric blend?

It is mostly cotton with a small amount of elastane, which gives the brief stretch and helps it keep its shape in the wash.

How does it compare with Calvin Klein's Cotton Stretch brief?

The CK One Modern Brief sits lower and has a softer, flatter waistband. The Cotton Stretch line uses a similar blend but a higher rise and a more prominent logo band.

Does the waistband roll or dig in?

Most owners say the flat band stays in place and does not roll. A few with larger builds find it snug.

What comes in the pack?

Three briefs in the colors shown for the pack you choose. Colors are fixed per pack, so you cannot mix shades.

Is it good for workouts?

It works for light exercise, but the cotton blend dries slower than synthetic sports briefs, so it is better for daily wear than heavy training.
