Scuba Diving Thermal Packages — Complete Exposure Protection in One Purchase

Divers rarely get cold uniformly. They get cold in one specific place, and that one place ends the dive. A 7mm suit with no hood loses heat through the head fast enough to cut a dive short. A good suit and hood with thin gloves leaves you unable to work a clip. Exposure protection functions as a system, and the weakest component sets your actual limit — not the thickest one.

That's the reasoning behind these packages. Each bundles a wetsuit with the hood, gloves, and boots matched to it, so the whole system is rated for the same conditions and the sizing works together. Warm-water packages pair a shorty with gloves and boots. Nothing is left as an afterthought purchase you make later, after your first cold dive.

At DiveCatalog.com we carry thermal packages from Bare, Scubapro, and Hollis as an authorized dealer for every brand.

Matching Thickness to Water Temperature

Treat these as starting points rather than rules. Cold tolerance varies genuinely between individuals, and dive duration matters as much as temperature — an hour at 20°C chills you far more than twenty-five minutes at the same reading. Repetitive diving compounds it further, since you start each dive already cooled from the last.

If you're between two options, size up on warmth. You can always flush a suit that's too warm; you can't add insulation at depth.

What's In a Package

• Full thermal packages — wetsuit, hood, gloves, and boots, matched for thickness and conditions
• Warm water packages — shorty wetsuit, gloves, and boots; no hood, since head insulation isn't the limiting factor in tropical water

Buying the components separately works, but it puts the burden on you to match thicknesses sensibly and to size items that interact — boots determine fin size, and hood bibs need to sit correctly under the suit collar.

The Brands

Bare covers the widest range here, with the Revel and Reactive lines for men, Elate and Evoke for women, and the premium Nixie Ultra and Velocity Ultra 2.0 at the top of the range including semi-dry configurations.

Scubapro brings the Definition line built on their Body Map System 3D cut, the Sport and Sport Steamer ranges, and Everflex Yulex — which delivers comparable thermal performance using plant-based Yulex rather than petroleum neoprene.

Hollis contributes the Neotek semi-dry package for genuinely cold conditions.

Getting the Fit Right

A wetsuit works by trapping a thin layer of water against your skin and letting body heat warm it. That only happens if the suit is snug everywhere — gaps at the lower back, under the arms, or behind the knees flush cold water through continuously and the suit never warms up.

Snug isn't the same as restrictive. You should be able to fill your lungs completely, reach overhead, and squat without the suit fighting you. If you can pinch a fold of loose neoprene anywhere, size down. If you can't zip it comfortably, size up.

Neoprene sizing varies considerably between manufacturers, so check the chart for the specific model rather than assuming your size carries across brands. Send us your chest, waist, hip, height, and weight measurements and we'll confirm before you order.

Frequently Asked Questions

Is a package better than buying the pieces separately?

Usually, for two reasons. The components are matched for thickness so you don't end up with a 7mm suit and 3mm gloves, and bundles are priced below the sum of the parts. Buying separately makes sense if you already own good boots or need an unusual combination.

Where do I lose the most heat?

The head, which is why a hood is included in every full package and why it's the single most cost-effective warmth upgrade available. Extremities follow — hands and feet chill fastest and affect your ability to function long before your core is genuinely cold.

What is a semi-dry suit?

A wetsuit with substantially improved seals at the wrists, ankles, and neck, plus a sealed zipper, that dramatically reduces the water flushing through during a dive. Water still enters, but it stays put and stays warm. It bridges the gap between a 7mm wetsuit and a drysuit.

How do I choose between two thicknesses?

Consider your typical dive duration and how many dives per day. Long dives and repetitive diving both call for more insulation than the temperature alone suggests. When genuinely undecided, choose the warmer option.

Do the boots affect my fin size?

Yes, significantly. Open heel fins are sized to the boot, not your foot, and a 7mm boot is considerably bulkier than a 3mm one. If you're buying a package with thicker boots than you currently dive, check your fins still fit over them.
