A drysuit keeps you dry by sealing water out at the neck, wrists, and a waterproof zipper. Warmth comes from the undergarments you wear inside. That's the key difference from a wetsuit, and it's why drysuits unlock cold-water diving, long surface intervals in winter, and year-round local diving. Wondering whether you need one at all? Our is a drysuit worth it guide covers that decision.
This guide breaks down the materials, the features that matter, and our picks by type. One caveat up front: fit matters more than brand. A mid-range suit that fits you properly beats a premium suit that doesn't, so try suits on or use a dealer that offers custom sizing whenever you can.
Drysuit materials explained
| Material | Warmth on its own | Weight and packing | Durability | Best for |
|---|---|---|---|---|
| Trilaminate | Low; warmth comes from undergarments | Light, packs small, dries fast | Tough, easy to repair | Travel, variable temperatures, most divers |
| Crushed or compressed neoprene | Some built-in insulation | Heavier, bulkier | Very durable, abrasion resistant | Cold local diving, rough shore entries |
| Standard (foam) neoprene | Good built-in insulation | Bulky, slow to dry | Good | Very cold water; buoyancy changes with depth |
| Hybrid / breathable shells | Low | Light | Varies by construction | Comfort on the surface and boat |
Trilaminate suits are a thin, three-layer shell. They have almost no buoyancy of their own, so the suit's buoyancy stays consistent at depth. You adjust warmth by changing undergarments, which makes them versatile and travel-friendly.
Crushed neoprene is neoprene compressed so it loses most of the gas cells that make standard neoprene buoyant and compressible. It's tough, flexible, and somewhat warmer than a shell. It's also heavier to haul around and slower to dry.
Standard foam neoprene drysuits insulate on their own, but they compress with depth like a wetsuit, changing buoyancy and warmth as you descend.
Features that matter more than the logo
Seals
- Latex seals are the traditional choice. They seal well and are inexpensive to replace, but they degrade with sun, ozone, and oils, and some people are allergic to latex.
- Silicone seals last longer, stretch comfortably, and suit people with latex allergies. They can be more delicate to tearing.
- Neoprene seals are warm and durable but can be harder to get a perfect seal with.
Look for a suit with a user-replaceable seal system, such as click-in or ring-based seals. You can swap a torn seal on a dive trip in minutes instead of shipping the suit off for repair.
Zipper type and placement
- Front or diagonal zippers let you get in and out without help.
- Back zippers usually need a buddy to close.
- Metal zippers are the durable classic.
- Plastic waterproof zippers are more flexible and lighter, but can be less rugged.
Zipper care, such as waxing or lubricating as directed, extends life significantly.
Boots or socks
- Attached boots are convenient and warm.
- Latex or neoprene socks require separate rock boots but give a better fin fit and more ankle flexibility.
Sock-style suits are popular with divers who care about finning technique, because they reduce the floaty-feet feeling.
Valves and pockets
Every suit has an inflator valve, usually on the chest, and an exhaust or dump valve, usually on the left shoulder. Thigh pockets are useful for SMBs, spare masks, and wet notes. A relief zipper is a welcome feature on long dives for some divers.

Getting the fit right
- Wear your undergarments when trying suits on. A suit that fits over a T-shirt may be tight over a thick undergarment. See our {link('best-drysuit-undergarments','drysuit undergarment picks')}.
- Test the full range of motion. Reach behind your head for your tank valve, cross your legs, kneel, and bring a knee to your chest as if putting on fins. Tight spots underwater become restrictions.
- Check torso length. Too short and the suit pulls when you bend. Too long and you'll have excess material that traps air.
- Consider custom sizing. Many manufacturers offer made-to-measure options at a modest upcharge. For hard-to-fit body types, it's worth it.
- Get trained. A drysuit course teaches buoyancy control, venting, and emergency skills. Our {link('first-drysuit-dives-buoyancy','first drysuit dives guide')} covers what to expect.
Frequently asked questions
What is the best material for a drysuit?
Trilaminate suits are light, travel well, and keep buoyancy consistent, with warmth coming from undergarments. Crushed neoprene is more durable and warmer on its own but heavier. The best choice depends on where and how you dive.
Are silicone or latex drysuit seals better?
Silicone seals last longer and suit people with latex allergies, while latex seals are inexpensive and seal well. Replaceable seal systems make either choice easier to maintain.
Do I need training to dive a drysuit?
Yes. A drysuit course covers buoyancy control, venting, and emergency skills that differ from wetsuit diving.
Does a drysuit keep you warm by itself?
Mostly no. A drysuit keeps you dry, and warmth comes from the undergarments you wear inside it. Neoprene suits add some insulation of their own.
Should I buy a drysuit with boots or socks?
Attached boots are convenient and warm. Socks with separate rock boots give better fin fit and ankle flexibility. Both are common.
