Kids/Junior Thermal - SHORT Sleeve Polypro Rash Vest

Keep kids warmer for longer in cold water with our Kids’ Thermal Short Sleeve Rash Guard. Designed to work as a technical base layer or as an extra insulating layer under a wetsuit, it delivers excellent warmth even when wet while absorbing minimal water—so children stay more comfortable during longer sessions.

Ideal for surf school, open water swimming, triathlon swim training, SUP, kayaking and general watersports, this thermal rash vest also helps reduce wind chill on exposed days. It’s a simple upgrade that can make a big difference to confidence and enjoyment—especially for kids who feel the cold.

Best For

• Surf lessons & beach days when the water is chilly
• Open water swimming and cold water confidence-building
• Triathlon club swim training (extra warmth without bulky layers)
• SUP, kayaking & sailing where wind chill bites
• Layering under wetsuits to extend the season and reduce post-session shivers

Warmth Without Bulk (Made for Movement)

The Thermotech microfibre lining traps warmth efficiently with minimal bulk, while the outer coating helps wick water away to reduce evaporative cooling. 4-way stretch and anatomically shaped panels support comfortable movement for paddling and swimming, and flatlock seams help reduce rubbing for all-day wear.

Technical Features

• Polypro Thermotech lining for excellent insulation using low-bulk microfibre fabric
• Quick-dry microfibre lining for comfort between sessions
• Durable water-resistant coating for improved warmth and water-wicking performance
• Flatlock stitched seams for breathable, comfortable construction
• 4-way stretch with anatomically shaped panels for natural movement
• Performance fit designed to sit close to the body for effective layering
• UV protection (UPF 50+)

Parent tip: For the best warmth, choose a close fit (especially if it will be worn under a wetsuit). If your child is between sizes or prefers a slightly looser feel as a stand-alone top, consider sizing up.
