Softer than my PJs.
Most trunks I've tried tend to slide down or the legs roll up. These stay exactly where you put them. High quality elastic on the waist.

Many thanks for the feedback! We put a lot of work into the waistband elastic and leg grip to ensure they stay put without rolling. Brilliant to hear they’re outperforming other brands you've tried!
