Men's Second Skin Trunk Underwear - 360 Stretch Modal Comfort

Our review of these trunks finds them ideal for anyone who wants underwear that feels like a second skin. The single biggest reason to buy is the fabric: a 90% modal, 10% spandex blend delivers an unusually soft, breathable feel that stays smooth after repeated washes. The trunks aim to replace cotton for everyday wear while adding a supportive contour pouch and a Horizontal Quick Draw Fly for practical use. Comfort-focused details like a tagless label and a Stay-Put waistband make them a consistently easy choice for daily use.

Key Features

• 360 Stretch Fabric: The modal and spandex blend moves with the body for a barely-there fit that reduces bunching under clothes.
• Contour Pouch: The supportive pouch keeps everything positioned comfortably while providing discreet shaping under trousers.
• Horizontal Quick Draw Fly: The fly opens quickly for convenient bathroom breaks without compromising the trunk's low profile.
• Breathable, Non-Pilling Material: Modal-based fabric breathes better than cotton and resists lint balls and fuzz after multiple washes.
• Stay-Put Waistband: The waistband is designed not to roll or pinch and the tagless label eliminates chafing at the back.
• Easy Sizing: Clear waist ranges for S through XXL help select the right fit for common men's sizes.

Who It's For

These trunks are best for men who prioritize softness and breathability and who wear fitted pants or work in environments where underwear that stays smooth matters. The modal stretch fabric is particularly suited to people sensitive to chafing or who prefer lightweight layers next to skin.

Those seeking heavy-duty longevity for extreme wear, or who need a high-rise brief, should look elsewhere. Also, men who consistently experience ride-up with trunks may want to test a pair first, as some users report fit differences on the inner thigh.

Pros & Cons

Pros

• Exceptional softness and breathability from the modal stretch fabric that feels luxurious against skin.
• Supportive contour pouch and a practical Horizontal Quick Draw Fly for daily convenience.
• Stay-Put waistband and tagless design reduce rolling and irritation for comfortable all-day wear.
• Non-pilling material keeps the trunks looking newer longer compared with standard cotton.

Cons

• Durability reports are mixed; some users note limited lifespan after many washes compared with sturdier blends.
• A few customers experience brief ride-up on the thighs depending on body shape and sizing choice.
