This Hotline GT 4/3mm Chest Zip Full Wetsuit isn't just neoprene. It's serious warmth, serious mobility, and a seriously clean entry without the serious price tag. Designed by Hotline, the wetsuit makers from Santa Cruz since 1979, this suit is built to last.

The best part? You won't find better quality at this price point.

Key Features:

• Original FlyZip Chest Entry: Hotline's signature chest zip system seals out water better than a back zip ever could. You stay warmer longer with a cleaner fit through the shoulders.
• 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 mean you're suiting up fast and spending more time in the water and less time wrestling neoprene 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 stand up to the abuse of repeated pop-ups, rocky entries, and everything 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.
