Quick answer: This is a piece of exposure protection from DUI. It's offered in XXL and up, which puts it in our extended-size collection.

Why bigger divers look at it

Sizing for the body you have, instead of squeezing into the largest size a brand happens to make, is the whole point. A suit with room through the chest, waist and hips stays comfortable for the full dive and still keeps you warm.

What you get

• Stay warm and dry in water temperatures from 45-60°F with these DUI mid layer socks.
• Superior comfort and moisture management with Active Wicking Technology (AWT).
• Designed as the perfect undergarment for your drysuit, ensuring a snug and secure fit.
• These durable DUI socks offer exceptional warmth and insulation for extended dives.
