DUI says it adds about 5 degrees of extra insulation when layered.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy bigger divers look at it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eDrysuit undergarments need to stretch, because they live in a tight space between you and the suit. DUI builds this vest from all-way stretch fleece, so it moves with a broad chest and shoulders instead of riding up. A vest also keeps your core warm without adding bulk to your arms, which helps when you're reaching for valves or a drysuit inflator.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat you get\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHeavy stretch fleece, 560 g\/m²\u003c\/li\u003e\n\u003cli\u003ePill-resistant, watershed outer jersey\u003c\/li\u003e\n\u003cli\u003ePlush velour lining\u003c\/li\u003e\n\u003cli\u003eZipper closure and hand-warmer pockets\u003c\/li\u003e\n\u003cli\u003ePart of DUI's ActionWear Pro DiveWear line\u003c\/li\u003e\n\u003cli\u003eMen's sizes XS through 2XL\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eBefore you buy\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTry your drysuit on over the vest and your other layers before the dive.
