What’s The Deal With…?

Mastering the Waves

Seams are where the warmth escapes! Flatlock stitching is classic and flexible but lets in tiny amounts of water (great for warmer suits). Glued & Blind-stitched (GBS) is the gold standard—the seams are glued, then stitched without piercing all the way through, making them way more watertight. Liquid taped seams have a waterproof sealant painted on the inside for the ultimate barrier. For cold water, you want GBS with liquid taped seams. It’s the difference between being chilly and being totally locked in.

It’s a genius bit of science, dude. The suit lets a thin layer of water in next to your skin. Your body heat warms that water up, and the neoprene (that rubbery material) traps it there, creating a toasty thermal layer. The suit itself doesn’t warm you—you warm the water. That’s why a good, snug fit is crucial; too loose and all that warm water flushes out with every duck dive, replaced by cold ocean. That flush is a real buzzkill, so seal it up tight at the neck, wrists, and ankles.

It’s all about water temp, brah. Thickness is in millimeters, like 3/2mm (3mm torso, 2mm limbs). Warm, tropical water? A light 2mm spring suit or just boardshorts. Most California vibes? A 3/2mm full suit is your go-to. Frigid, icy winter sessions? You’ll need a 4/3mm or even a 5mm+ hooded suit. The right thickness lets you move freely while keeping the core stoke warm. Too thin and you’ll freeze; too thick and you’ll overheat. Match it to your local break for maximum water time.

Mastering the Waves

The holy trinity of cold-water accessories! When the water or air gets seriously chilly, your extremities feel it first. Boots are essential for grip on icy wax and protecting your feet from reef or rocks. Gloves keep your hands from going numb so you can actually feel your board. A hood is the ultimate game-changer—you lose a ton of heat through your head. If you’re debating needing one, you probably do. They keep you out longer and stoked, not shivering on the beach.

It’s the battle of the entry systems! The classic back zip is easy on/off but can let in more water. The chest zip (or zip-free) is the modern standard for most surfers—way better seal, more flexibility, and less flushing. Zipless (or entry systems with minimal zippers) are super flexible and comfy, like a second skin, but can be a mission to get on and off. For performance and warmth, chest zip is king for many. For maximum flex and you don’t mind the struggle, go zipless.

Totally, a quick DIY fix can extend your suit’s life. For small nicks or tears, get some neoprene cement. Clean the area, apply a thin layer, let it get tacky, then press the pieces together. For a blown seam, a flexible aquaseal or wetsuit sealant works. Just go easy and keep it ventilated—that stuff is potent! But for major rips or critical seam failures, take it to a pro repair shop. A proper patch job can save you from buying a new suit for another season.
