Hoods, Gloves & Boots: A Cost Guide to Thermal Extremities
Your extremities lose heat fastest. Here is what thermal protection for your head, hands and feet costs, and how to choose thickness without overspending.
Most divers obsess over the wetsuit and forget that the body loses heat fastest through the head, hands and feet. A diver who is comfortable in the core but has numb fingers and a cold scalp will end the dive early, lose dexterity, and slowly drift toward a miserable surface interval. Hoods, gloves and boots are the cheapest comfort upgrade in diving, yet they are often bought badly: too thin, too thick, or sized so loosely that they flush cold water on every kick.
This guide covers what thermal extremities actually cost, how thickness maps to water temperature, and where spending a little more genuinely changes your dive. As always, treat the numbers here as ranges. For current pricing across brands and shops, check the live verified prices on DiveCost.
Why extremities matter more than you think
Heat loss is driven by surface area and blood flow. Your head is densely supplied with blood vessels and is rarely covered by anything but a thin hood, so it sheds warmth quickly. Hands and feet sit at the end of long circulatory loops; when your body decides to protect the core, it restricts flow to the extremities first. That is why your fingers go numb long before your chest feels cold.
The practical consequence is simple. Adding a hood can do more for warmth than adding a millimetre to your suit. Good gloves keep you task-capable. Boots keep your feet warm and protect them from fin chafe, hot boat decks and sharp entries. None of these are expensive relative to the rest of your kit.
Choosing thickness by water temperature
Thickness is measured in millimetres of neoprene. The right choice depends on water temperature, dive duration, and how cold-sensitive you are. These are sensible starting points, not rules:
- Warm tropical water (above 26C): often no hood, 1.5-2mm gloves if any, 3mm boots for fin comfort and protection.
- Temperate water (18-25C): 3mm hood, 3mm gloves, 3-5mm boots.
- Cool water (12-18C): 5mm hood, 5mm gloves, 5mm boots.
- Cold water (below 12C): 5-7mm hood, 5-7mm gloves or dry gloves, 6.5-7mm boots, often with a dry suit.
Fit beats thickness
A 5mm glove that flushes water on every wrist movement is colder than a well-fitted 3mm. Seal at the wrist, ankle and face matters more than raw millimetres. Try before you buy whenever you can.
What they cost
Thermal extremities are among the most affordable gear you will buy. Hoods and gloves rarely break the bank, and even premium boots cost a fraction of a regulator. The table below shows typical price tiers. Cold-water and dry-glove systems sit at the top end because of the materials and sealing involved.
| Dive hood (3-7mm)Bibbed and vented designs cost more | EUR 20-70 |
| Wet gloves (1.5-5mm)Pre-curved and Kevlar-palm at the top end | EUR 20-60 |
| Dry glove systemCold-water; needs compatible dry suit | EUR 120-300 |
| Dive boots (3-7mm)Hard-sole, zipped boots cost more | EUR 30-90 |
| Typical wet kit (hood + gloves + boots) | EUR 70-220 |
Where spending more pays off
On hoods, a vented design that lets trapped air escape is worth the small premium; it prevents the awkward buoyancy bubble under your chin. A bibbed hood that tucks into your suit reduces flushing at the neck. On gloves, pre-curved fingers reduce hand fatigue on long dives, and a reinforced palm survives years of grabbing reef hooks, ladders and tank valves. On boots, a hard sole protects your feet on rocky shore entries and hot boat decks, and a sturdy zip with a gusset keeps grit out.
The hidden cost of cheap boots
Thin, soft-sole boots wear through at the heel within a season of shore diving, and a worn boot lets your fin slip and chafe. A mid-range hard-sole boot often outlasts two cheap pairs, making it cheaper per dive over time.
Sizing and fin compatibility
Boots and fins are a system. Open-heel fins are sized to fit over a booted foot, so buy or test them together. A boot that is too bulky will not fit your fin pocket; one that is too thin leaves the foot pocket loose and lets the fin twist. If you already own fins, take them to the shop or note the foot-pocket size before ordering boots online.
For hoods and gloves, snug is correct. Neoprene compresses at depth, so a glove that feels slightly tight at the surface will feel right at 20 metres. Too loose and it floods; too tight and it cuts circulation, which defeats the purpose by making your hands colder.
DiveCost tracks current prices
Hood, glove and boot prices shift with season and brand promotions. We track live verified prices across shops so you can see what a given thickness actually costs today rather than guessing from an old catalogue.
Putting it together
If you dive mostly warm water, a single set of 3mm boots and thin gloves covers almost everything, and you can skip the hood until you travel somewhere cooler. If you dive temperate or cold water regularly, budget for a proper 5mm set and treat it as the comfort multiplier it is. Either way, thermal extremities are the rare upgrade that costs little and changes every dive. They pair naturally with the wetsuit decision, which carries far more of your thermal budget.
