The O’Neill Men’s Thermo-X Long Sleeve Crew is designed as a high-performance base layer that delivers warmth, protection, and flexibility without added bulk. Ideal for cold-water sessions or layering under a wetsuit, it provides a comfortable, streamlined fit that won’t interfere with movement or gear.
Constructed with quick-drying, 4-way stretch fabric, it offers excellent mobility while retaining heat to keep you comfortable in cooler conditions. UPF 50+ protection adds an extra layer of defense against the sun, while strategic seam placement helps reduce chafing. With a low-profile neckline for easy layering, it’s a reliable choice for surfers and water athletes looking for lightweight insulation and performance.
