How to choose baby & toddler swim bottoms

They all go over a swim nappy, or on their own once your toddler is out of nappies. Choose by how much you want covered.

  1. Swim shorts Swim shortsHips and thighs
  2. Swim leggings Swim leggingsHips to the ankles
  3. Two-piece sunsuit Two-piece sunsuitArms, body and legs to the ankles

Coverage The two-piece sunsuit covers the most, with a long sleeve top and full-length leggings. Swim leggings cover from the waist to the ankles, which protects the knees and shins of a toddler kneeling and digging in hot sand. Swim shorts cover the hips and thighs and are the quickest to pull up and down. Shorts and leggings pair with a swim top.

Sizes Toddler swim shorts and swim leggings come in age 2 years, and the two-piece sets in 12 to 18 months.

Common questions about toddler & baby swim leggings and shorts

Swim leggings or swim shorts for a toddler?

Leggings for long days outside, shorts for quick dips. A toddler spends the day kneeling, digging and sitting in the sand, so the knees and shins get hours of sun and are hard to keep creamed. Swim leggings cover them down to the ankle. Swim shorts are cooler and the quickest to pull down, which helps during potty training. Many parents pack both and swap at lunchtime.

What age are the toddler swim leggings and shorts for?

The toddler swim leggings and swim shorts are sized for age 2 years, and the two-piece sets with leggings or shorts are sized 12 to 18 months. For a younger baby, a one-piece baby sunsuit covers more and stays in place. When your toddler grows out of the 2 years size, the next sizes up are in kids' shorts and leggings.

Do swim leggings go over a swim nappy?

Yes. The swim nappy goes on first and the leggings or shorts over it, like ordinary trousers over a nappy. The elastic waistband holds over the nappy without digging in. To change the nappy, pull the leggings down, which is quicker than unzipping a whole sunsuit. Once your toddler is out of nappies, the leggings and shorts are worn on their own.

Are swim leggings the same as swim pants?

No. In the UK, swim pants usually means a swim nappy: the snug pants that contain accidents in the water. Swim leggings, sometimes called swim tights, are full-length leggings in swim fabric that give certified UPF 50+ sun protection to the legs. A toddler still in nappies needs both for an outdoor pool: the swim pants for the water, the leggings for the sun.

Can toddlers wear swim leggings in the pool?

Yes. Toddler swim leggings and swim shorts are made from chlorine-resistant swim fabric, so they go in the pool and the sea like any swimwear and dry quickly afterwards. The UPF 50+ protection is in the weave, so it works wet or dry and does not wash out. Rinse them in fresh water after swimming to keep the fabric at its best.

Why choose equatorsun for baby and toddler swim bottoms?

Ordinary toddler and baby swim shorts are rarely tested for UV and they can let through up to 10 times more UV than UPF 50+ toddler and baby swim shorts. Every equatorsun piece is tested to the AS/NZS 4399 or EN 13758 standard and certified UPF 50+, which means the fabric blocks at least 98% of UVA and UVB rays from reaching the skin it covers, and because the protection is in the weave rather than a finish there is nothing to wash out or react with young skin.
