Second Skin Men's Trunk 4 Underwear - Soft Modal Stretch Comfort

In this review of the Second Skin Men's Trunk 4 underwear, the bottom line is simple: these trunks are designed for anyone who prioritizes everyday softness and a close, supportive fit. The biggest reason to buy is the fabric - a modal and spandex blend that feels luxuriously soft against skin and breathes better than cotton, making these trunks ideal for long days or travel. The review covers fit, construction, and real-world wear so you can decide if the trunks match your underwear rotation.

Key Features

• Modal stretch fabric: A 90% modal and 10% spandex blend offers a silky hand and natural breathability for comfortable all-day wear.
• Horizontal Quick Draw Fly: The quick draw fly provides fast, practical access during bathroom breaks without fumbling.
• Contour pouch: The supportive pouch keeps everything in place and reduces bunching under pants for a smoother silhouette.
• Stay-Put Waistband: The waistband is designed not to roll or leave marks, maintaining position through normal daily movement.
• Non-pilling construction: The fabric resists lint balls and fuzz so the trunks retain a clean, new look even after multiple washes.
• Tagless comfort: The absence of a sewn-in tag reduces irritation at the waist for sensitive skin.

Who It's For

These trunks are best for men who want a soft, lightweight pair of everyday underwear that will not feel bulky under pants. The modal-rich fabric and supportive contour pouch make them suitable for office wear, commuting, and travel when breathability and a smooth fit matter.

Those who need ultra-durable work underwear, or who prefer very thick cotton for heavy-duty tasks, may want to look elsewhere; some users report mixed durability experiences and occasional thigh ride-up depending on activity and body shape.
