What the AI looks for in Boys' Rash Guard Shirts
- Fit
- Snug, but not tight across the chest. A loose rash guard balloons with water and rides up, exposing skin.
- Sleeve length
- Long sleeve for all-day sun and short sleeve for warm pools. Shoulders and arms burn most in water play.
- Seams
- Flatlock seams. Raised seams chafe the underarms when kids paddle.
Brands that matter
- O'Neill: Rash guard specialist.
- Kanu Surf: Budget sets.
- Speedo: Pool-friendly rash guards.
- Coolibar: Sun-protective focus.
What to avoid
- Cotton tees in the water.
- Fits so loose that the shirt rides up in the water.
