Open Box Dive Wear — Everything You Wear In and Around the Water

This is the broad exposure protection category — the layers that go on before the tank does. Wetsuits, rash guards, hoods, gloves, boots, and the base and mid layers that make cold-water diving comfortable rather than merely survivable.

Dive wear returns almost always come down to fit rather than fault, which is why so much of it lands here in near-new condition. Every item is inspected and graded before listing; see Product Conditions for full definitions.

Building a Thermal System

Exposure protection works as a system, and the weakest point sets your limit. A 7mm suit with no hood loses heat through your head fast enough to cut a dive short. A good hood with thin gloves leaves your hands too cold to work a clip. Divers usually get cold at one specific point rather than uniformly — identify that point and address it directly.

The usual order of return on investment in cold water: hood first, then boots, then gloves, then suit thickness. A hood is inexpensive and prevents a disproportionate share of heat loss.

Sizing Across Brands

Dive wear sizing is not consistent between manufacturers, and this is the main reason items get returned. Your size in one brand tells you very little about your size in another. Always check the specific manufacturer's chart for the exact model, using your actual chest, waist, hip, height, and weight measurements.

Also size around what goes underneath. A suit fitted over bare skin will be tight over a rash guard; a drysuit fitted over light layers won't close over a heavy undersuit.

Frequently Asked Questions

Where should I spend first if I'm getting cold?

A hood, in most cases. Head heat loss is substantial and a hood is among the cheapest items in the category. After that, boots and gloves — extremities chill fastest and affect your ability to function. Increasing suit thickness is usually the last and most expensive step.

How do I size dive wear I can't try on?

Measure yourself properly — chest, waist, hips, height, weight — and compare against the manufacturer's chart for the exact model, not a general size guide. Contact us with your measurements and we'll help confirm before you order.

Does used neoprene still insulate properly?

Neoprene loses loft through repeated compression at depth, which reduces warmth over time. Items graded Open Box or Like New have seen little or no compression and perform essentially as new. Lower grades may have lost some insulation, which the price reflects.

Do open box items come with a warranty?

No. Open box and used products are not eligible for manufacturer warranty coverage.
