GT 4/3mm Back Zip Full Wetsuit - Premium Performance Without the Premium Price

Some wetsuits look the part but fall apart after a season. This one doesn't. The Hotline GT 4/3mm Back Zip Full Wetsuit is straightforward, dependable, and built for people who just want to get in the water without overthinking it. Designed by Hotline, the wetsuit makers from Santa Cruz since 1979, this is the suit that shows up every session and never lets you down.

No frills. No fuss. Just a really good wetsuit at a price that makes sense. The back zip is the classic entry for a reason. Easy to get in and out of, familiar to anyone who has worn a wetsuit before, and totally reliable. If you're new to surfing or just want a no-nonsense suit that does exactly what it's supposed to, the GT 4/3mm Back Zip is exactly that.

Key Features:

• Classic Back Zip Entry: The easiest way into a wetsuit, full stop. Pull the cord, step in, zip up, and go surf. Great for beginners and anyone who values a fast, familiar entry.
• YKK Zipper: The gold standard in zippers. Smooth, reliable, and built to handle session after session without skipping a beat.
• 100% Fluid Seam Seal: Every seam is fully sealed so cold water stays where it belongs, outside the suit. Zero flushes. All warmth.
• EZ On Wrist and Ankle Entry: Wider wrist and ankle openings make suiting up quick and easy, so you spend more time surfing and less time fighting your gear on the beach.
• Blind Stitched and Glued Seams: Triple-glued and blind-stitched construction means this suit handles years of sessions, not just a season.
• Gummy Super Stretch Neoprene: Thick enough for real warmth and flexible enough for full range of motion. Comfortable from paddle one.
• Durable Kneepads: Ultra-stretchy kneepads that move with you and hold up through pop-ups, rocky entries, and everything else the lineup throws at you.
• Unbeatable Value: Premium construction at a price that won't make you cry. Perfect as a first wetsuit for beginners or a solid backup suit for experienced surfers.

Why Choose the GT 4/3mm Back Zip? Because it works. You get the same professional-quality construction, sealed seams, and serious durability as suits that cost twice as much, wrapped up in the most user-friendly entry style there is. If you want a wetsuit that's simple to use, built to last, and won't wreck your budget, this is it.
