The best swimsuit for a 1-year-old depends on sun coverage, ease of dressing, and fit. For UPF 50+ protection, consider the upandfast full-zip suit for girls or the UMELOK one-piece with a sun hat for boys. The Simple Joys two-pack is a practical choice for families who want a spare, while the other one-piece options prioritize zip access and full-body coverage. Check the size chart and product details before ordering.

Simple Joys Two-Pack Rash Guards
Best for: Families who want a spare suit for vacations, swim sessions, or alternating between washes. This set includes two long-sleeve, one-piece rash guards with bright prints and colors.
The two-piece set was selected for its practical quantity and arm coverage. Having a second suit can be useful when one is wet or needs washing. The playful designs also make the suits easy to distinguish from plain swimwear.
Consider: The supplied details do not list a UPF rating. Long sleeves provide more coverage than a short-sleeve suit, but do not treat this product as rated UV protection unless the label confirms it.
upandfast Full-Zip Baby Girl Sunsuit
Best for: Caregivers looking for a one-piece suit with stated UPF 50+ protection and convenient dressing. Its full front zipper is designed to make putting the suit on and taking it off easier, and the listing says it can help with diaper changes.
The product details describe the fabric as soft, breathable, and quick-drying, and state that UPF 50+ material blocks 98.5% of harmful rays. A zipper tab at the top is intended to help keep the zipper from rubbing the baby’s neck or chest.
Consider: A full-coverage suit can still shift during play. Check the fit around the zipper and neck, and follow the care and sun-safety instructions on the garment.
Hnyenmcko Long-Sleeve Zipper Sunsuit
Best for: Families who want a stretchy one-piece with a choice of front or back zipper closure. The listed fabric is 82% polyester and 18% elastane, described as lightweight, breathable, quick-drying, and soft.
This option was selected for its broad listed size range, which includes 12–18 months and 18–24 months, and its playful dinosaur or marine-animal prints. The product details recommend checking the brand’s size chart, a useful step when choosing a suit for a growing 1-year-old.
Consider: The provided information does not state a specific UPF rating. Confirm the size chart and the garment’s sun-protection labeling rather than assuming the fabric provides rated UV protection.
UMELOK One-Piece Rash Guard With Sun Hat
Best for: Buyers seeking a boys’ one-piece with stated UPF 50+ protection and an easy-on design. The product features a front or back zipper, a zipper flap, and a zipper garage intended to protect delicate skin from the closure.
The listing describes the material as soft, durable, and stretchy, which may suit active babies who need room to move. It was selected for combining a one-piece rash guard, UPF 50+ claim, and included sun hat in one set.
Consider: The listing’s statement about full-coverage protection does not mean sunscreen or other sun precautions are never needed. Follow garment instructions and pediatric sun-safety guidance.
upandfast UPF 50+ Suit With Sun Hat
Best for: Caregivers who want a suit-and-hat set for beach or outdoor water activities. The listing describes the swimsuit as soft, stretchy, and durable, and states that its UPF 50+ fabric blocks 98.5% of harmful UV radiation.
The included hat is described as covering the baby’s face and neck, adding coverage beyond the one-piece suit. This product was selected for shoppers prioritizing both a stated UPF rating and a separate accessory for the head.
Consider: The hat may need adjustment during active play. Check that it fits securely and comfortably, and do not rely on a hat or swimsuit alone for complete sun protection.
Buying Guide: How To Choose A Swimsuit For A 1-Year-Old
Should you choose UPF 50+?
Compare the garment’s stated UPF rating if sun protection is a priority. In this selection, the upandfast and UMELOK listings specify UPF 50+. The Simple Joys and Hnyenmcko details provided here do not specify a rating. Coverage and a UPF claim are not interchangeable, so check the product label and care instructions.
Is a one-piece or two-piece set more practical?
A one-piece rash guard covers the torso and may reduce exposed skin compared with a separate top and bottom. A two-pack, such as the Simple Joys set, gives caregivers an extra suit. A suit that includes a hat, such as the UMELOK or upandfast option, adds a separate piece that may need repositioning.
What features make diaper changes easier?
Look for zipper placement and details that suit your routine. The upandfast full-zip suit is specifically described as convenient for diaper changes. Other listed suits offer front or back zipper closures to make dressing easier, but the supplied information does not specify a diaper-access opening.
How should you choose the size?
Use the product-specific size chart and compare it with the baby’s current measurements. Age labels can vary by brand, and a 1-year-old may fall between sizes. Choose a comfortable fit that allows movement without loose, shifting openings, and check the return policy before buying.
Frequently Asked Questions
What type of swimsuit is useful for a 1-year-old?
A comfortable one-piece rash guard with sleeves is a practical option for coverage. If rated sun protection matters, look for an explicitly stated UPF rating on the product or garment label.
Do all the swimsuits in this list have UPF 50+?
No. The supplied details state UPF 50+ for the two upandfast options and the UMELOK suit. They do not provide a UPF rating for the Simple Joys two-pack or Hnyenmcko suit.
Does a UPF 50+ swimsuit replace sunscreen?
No. Follow the garment’s instructions and current sun-safety guidance. A swimsuit does not protect skin that remains uncovered.
Is a zipper swimsuit easier to put on?
A zipper can make dressing easier, and the listed products describe front or back closures for that purpose. Check that the zipper area is comfortable and that any flap or tab is positioned correctly.
Should I buy a suit with an included hat?
Choose a hat set if you want a matching accessory for additional head coverage. Check the fit during wear, since hats can shift as babies move or play.
