The Vesuvius Boxer Briefs are a square-cut sports boxer with a 5-inch inseam. Their signature feature is the Caldera Pouch, a single-ply fabric cradle that lifts behind the testicles and hangs down for support and airflow. A low-profile StealthFly sits flush against the front. They suit men who want a supportive pouch and a shorter leg for training or hot days, and they compete with pouch-style briefs from brands like Saxx and Shinesty on pouch design rather than on fabric tech. Owners rate them very highly, with 4.9 out of 5 across 728 ratings.

Owners rate these boxer briefs very highly, with 4.9 out of 5 from 728 ratings. The pouch support and breathable fabric draw the most praise. A few mention an adjustment period for the pouch.
The Vesuvius Boxer Briefs have a 5-inch inseam and a square cut. They are made from form-fitting MicroModal fabric that holds softly and feels fresh through the day.
The Caldera Pouch is a larger, single-ply cascading front pouch. It lifts slightly behind the testicles and then droops down. The single-ply fabric is thin, bouncy and breathable. A horizontal StealthFly sits flush against the front with a barely visible profile.
The hems are seamless and sit at a low profile. The legs don't roll up or bunch up. The waistband is wide and ultra-smooth, so it won't mark the skin or cut circulation.
