upandfast Baby rashguard swimsuit with full-length zipper and UPF 50+ protection (toddler one-piece)
Product description
What this is and why parents look at it
This upandfast baby swimwear is a toddler one-piece rashguard with long sleeves and a full-length front zipper. In plain terms: it’s the kind of swimsuit you buy when you want more skin coverage than a typical swim set, plus a practical way to get it on and off without wrestling with tiny arms.
It’s designed for beach and pool days, with a soft, stretchy fabric that’s meant to handle real use (splashing, sand, repeated wears) without snagging or fading, at least on paper. The bigger selling point, though, is the UPF 50+ sun protection angle, paired with a full-length zipper for quick dressing and convenient nappy changes.
The sun protection and coverage you can expect
The suit is built around UPF 50+ sun protection, and the brand claims it can block 98% of harmful sun rays. On top of that, the long sleeves and one-piece design aim to cover both the upper body and the lower part, helping reduce the amount of exposed skin compared with sleeveless swimwear.

That’s useful if your priority is protecting children’s skin during longer outdoor sessions—think seaside trips, paddling pools, or garden splash-time when you’d rather not rely purely on reapplying sun cream. Still, do keep expectations sensible: even with UPF clothing, sunlight exposure management still matters (shade, timing, and any sunscreen you use).
What it’s like to use (zipper, comfort, and day-to-day practicality)
The full-length zipper is there for a reason. It makes getting dressed and undressed much easier than pulling an entire one-piece over the head, and the front design also helps if you need a diaper change without a full strip-down.
There’s also a detail for comfort: a tab at the top of the zipper intended to prevent it from irritating your child’s neck or chest. It’s a small thing, but for kids’ swimwear, small irritations are exactly what can turn an otherwise decent outfit into one they won’t tolerate for long.


The fabric is described as lightweight and quick-drying, so it should be less likely to feel heavy after swimming. And the suit is suggested to be hand washed with mild soap in cold water, then hang dry or lay flat.

Key features that stand out (and where it may fall short)
Where it shines
- Long sleeves and a one-piece cut for broader coverage.
- UPF 50+ positioning with a stated 98% sun-ray blocking claim.
- Full front zipper designed to simplify dressing and diaper changes.
- Soft, comfortable, stretchy fabric meant to hold up well to beach/pool wear.
A realistic limitation to consider
If you’re expecting the kind of swimwear that can be thrown in the washing machine and left to dry like a basic T-shirt, this one may not suit your routine. The care note is clear: hand wash in cold water and dry either by hanging or laying flat. It’s not a deal-breaker for everyone, but it’s worth factoring in if you want low-fuss laundering.

It may also feel like a more coverage-focused choice rather than a minimal, super-breezy style—depending on your child and the weather, that extra fabric could be a bit more “swim suit” than “barely-there”.
Who it’s for (and who might want to look elsewhere)
It makes sense if you’re looking for toddler swimwear with practical on/off dressing and more skin coverage than a standard swimsuit. It’s especially relevant if you regularly deal with quick changes, or you want long-sleeve protection for days out where sun exposure is hard to control.


Worth considering if: It makes sense if you prioritise UPF 50+ coverage and day-to-day convenience from a full-length zip.
It might not be a great match if: You may want to skip it if you strongly prefer machine-wash swimwear, or you’re after a very lightweight, low-coverage style for hot, sunny days.

Care & washing notes you should follow
Hand washing in cold water with mild soap is recommended, followed by either hang drying or laying flat to dry. If you’re not keen on hand washing after every swim session, this is the moment to check whether your lifestyle matches the care instructions. Washing method matters more than people expect, especially for clothing positioned around UV protection.
Final verdict
A solid pick if you want a toddler rashguard-style one-piece with long sleeves, UPF 50+ sun protection positioning, and an easy full-length zipper for dressing and diaper changes. It’s not the best choice if you need machine-wash convenience or you prefer very minimal swimwear coverage.
When it makes the most sense is during beach and pool days where you’d rather cover more skin and manage changing quickly. If you can handle hand washing and don’t mind the “more coverage” feel, it should fit the bill.
