Long Sleeve Bikini

What Is a Long Sleeve Bikini?

Long sleeve swimwear covers the arms to the wrist with swim fabric — the format most people know as the rash guard. The sleeves protect shoulders and arms from the sun during long water days, and the stretch swim knit keeps the piece usable in the water rather than as a dry cover only.

This collection holds 40 styles from about $17 in the long sleeve read: rash-guard one-pieces and covered-top sets lead, with long-sleeve cover pieces sitting alongside. The honest note: the pool is the long sleeve format across the store’s sun-protection range.

Sun Protection, by the Numbers

Long sleeve swim pieces carry sun-protection ratings — most list UPF 50+, which blocks around 98% of UV radiation. The rating on the listing is the number to trust: UPF is a tested property of the fabric, not a marketing phrase.

• UPF 50+: blocks about 98% of UV rays
• Coverage: sleeves protect arms and shoulders
• Fabric: quick-dry polyester-spandex knits

Sunscreen still goes on the uncovered areas — face, hands and legs — and re-application matters after swimming. The sleeves reduce the area to protect rather than replacing sunscreen.

Rash Guard vs Regular Swim

Rash guards were built for water sports — surfing, snorkeling and paddling — where the fabric also guards against chafe from boards and gear. The same qualities suit any long water day: covered arms, quick-dry knit and stretch that moves with swimming.

The trade-off is the same as any coverage: long sleeves hold heat more than bare skin and need a bit more care to dry. On the water they are the practical format for full-day sun exposure.

What This Pool Carries

The 40 styles here split across formats. Rash-guard one-pieces give full torso and arm coverage in a single garment — the simplest sun setup. Long sleeve tops pair with bikini bottoms as two-pieces, mixing coverage where you want it. Long-sleeve cover pieces round out the pool.

Choose by how you will wear it: one-pieces for maximum simple coverage, tops for mixing with bottoms you already own, and print options from tropical to tiger to match the style you like.

Fit and Care

Long sleeve swim pieces size by chest and torso measurements — the sleeves add length to the garment, so the listing’s size notes and photos matter for the fit. Rash-guard cuts run close to the body by design, holding the fabric against the skin for sun coverage.

Care follows the knit: rinse after salt or chlorine, wash gentle, dry flat. Rash-guard fabric keeps its UPF rating longest when it skips hot dryers and harsh detergents, which break down the fibers and the sun protection over time.
