What the AI looks for in Men's Trunks Underwear
- Inseam
- Roughly 2 to 4 inches, shorter than a boxer brief A short leg gives a clean line, but the hem has to grip or it rolls up.
- Hem finish
- A bonded or no-roll hem On short legs, curling hems are the most common way trunks fail.
- Fabric
- Modal or microfiber with elastane for a smooth look under fitted clothes Thin, smooth fabric avoids visible lines and bulk.
Brands that matter
- Tommy John: Premium soft trunks.
- Calvin Klein: Classic trunks in cotton and microfiber.
- 2(X)IST: Fashion-focused trunk styles.
- SAXX: Pouch-style trunks.
What to avoid
- Trunks with thick rolled leg elastic.
