I. Differences Between Rash Guard Sets and One-Piece Sunsuits

1. Rash Guard Set

* Covers arms and upper body for enhanced outdoor sun protection
* Separate bottoms allow older children to use the restroom independently
* High freedom of movement for running, jumping, sand play, and water activities
* Suitable age: Preschoolers and older children (3–8 years)
* Ideal scenarios: Beaches, outdoor pools, outdoor sports, water parks

2. One-Piece Sunsuits

* High coverage
* One-piece design minimizes shifting during movement
* Enables quick diaper changes
* Suitable age: Infants to toddlers (3–36 months)
* Ideal for: Indoor pools, short outdoor water play, infant swim classes

II. Which is best for your baby?

1. Infants 3–36 months → One-Piece Swimwear

Requires diaper changes, limited mobility
* Baby has delicate skin, sensitive to sun and cold
* One-piece UPF 50+ covers more body areas
* Reduces sand ingress and prevents cuff rolling

* Non-stifling and non-irritating to skin
* Good elasticity, form-fitting without tightness
