Boyleg Swimsuit vs Board Shorts: Kids Swimwear Compared

Compare a long-sleeved boyleg swimsuit and cotton board shorts on sun protection, coverage, and comfort so you can pick the right kids swimming outfit.
Quick answer
For pool or beach days with strong sun, choose the Sunny Days One Piece Boyleg Swimsuit because its long sleeves and UPF 50+ recycled polyester give more coverage. Choose the Swim Board Short for breathable cotton comfort during active sand and surf play, but pair it with a rash top for sun protection.
Sun protection is the biggest difference
The boyleg swimsuit carries a UPF 50+ rating, so the fabric itself blocks a large share of UV rays on the covered areas. The board shorts have no stated UPF rating, so they should not be treated as sun-protective on their own. If your child will be in direct sun for long stretches, the boyleg swimsuit reduces how much sunscreen you need to reapply on the torso and arms.
Fabric changes how each piece feels wet and dry
The swimsuit is made from recycled polyester, which is typical for swimwear that needs to hold its shape in water and dry reasonably fast. The board shorts are 100% breathable cotton, which feels soft and airy on land but stays wet longer and is not designed as a performance swim fabric. For a child who spends most of the day in the water, the polyester swimsuit is the more practical choice; for a child who alternates between sand play and quick dips, cotton shorts feel more comfortable between swims.
Coverage and dressing differ for toddlers and older kids
A one-piece boyleg swimsuit covers the torso, upper legs, and arms in one garment, which means fewer pieces to keep track of and less exposed skin. The back zip with a self-fabric puller helps with dressing, but a one-piece still takes more effort to get on and off than a separate short, especially for a wriggling toddler or a child who needs the toilet often. Board shorts with a soft elasticated waistband are quick to pull on and off, which suits toilet training and older kids who dress themselves.
When the price difference matters
At catalog prices, the boyleg swimsuit is listed at USD 34.47 (compared with USD 49.95) and the board short at USD 29.96 (compared with USD 39.95). The swimsuit costs more but replaces both a top and bottom for sun coverage, while the board short is a lower-cost separate that may need a rash top added for full protection. Neither price includes any accessories, and the swimsuit's available colour, fabric, and size options should be checked before ordering.
Trade-offs to weigh before you buy
- Sun coverage vs breathability: The boyleg swimsuit gives UPF 50+ coverage over arms and legs, but recycled polyester feels less airy than cotton when dry. The cotton board shorts breathe well on land but offer no stated UPF protection. If sun exposure is high, prioritize the UPF-rated swimsuit; if comfort between swims matters more, choose shorts plus a rash top.
- One-piece convenience vs quick changes: A one-piece means one garment to manage, but the back zip and full coverage make toilet breaks slower. Elasticated board shorts are faster for toddlers in toilet training and for older kids dressing themselves. Consider your child's toileting independence before choosing a one-piece for full pool days.
- Cost per covered area: The boyleg swimsuit is priced at USD 34.47 and covers top and bottom; the board short is USD 29.96 but may need a separate rash top for equivalent sun protection. Compare the total cost of shorts plus a protective top, not just the shorts alone.
Product facts at a glance
- Sunny Days One Piece Boyleg Swimsuit: Long-sleeved boyleg one-piece made from recycled polyester and rated UPF 50+, with a back zip and self-fabric puller. It covers arms, torso, and upper legs in one piece, so there is less skin to sunscreen and fewer items to pack.
Sunny Days One Piece Boyleg Swimsuit - Swim Board Short: Board shorts made from 100% breathable cotton with an all-over stripe print and a soft elasticated waistband. They are easy to pull on and off and feel airy on land, but cotton is not a UPF-rated swim fabric, so pair them with a sun-protective top.
