UPF 50+ long-sleeve rash guards for men

Why long-sleeve protection matters

Long-sleeve rash guards give you maximum arm and torso protection. Full coverage blocks UV rays on forearms and wrists—the areas that short-sleeve rash guards leave exposed. Water reflects and intensifies harmful rays, making these spots prone to burns even on overcast days.

A snug fit prevents fabric from shifting during active movement, maintaining consistent protection throughout your session. Unlike loose-fitting shirts that balloon with water and create drag, rash guards stay positioned for unrestricted movement during surfing, swimming, and diving.

Sun damage accumulates over time. Extended water activities expose your skin to direct UV rays and reflected radiation from water surfaces. This double exposure can cause burns in as little as 15 minutes during peak sun hours. Long sleeves eliminate the need to constantly reapply sunscreen to covered areas.

The Skin Cancer Foundation has awarded our products its Seal of Recommendation, confirming that our fabrics meet strict standards for UV protection.

Fabric that performs and lasts

Our materials resist chlorine breakdown, preventing fading and loss of protective properties during pool use. Saltwater resistance keeps the fabric flexible and comfortable during ocean activities.

Flatlock seam construction lies flat against your skin, preventing chafing during repetitive movements, like swimming or paddling. Reinforced stress points at shoulder seams and zipper attachments resist tears during frequent use.

UV stability in the fabric prevents degradation from sun exposure. Our fabrics maintain their UPF rating throughout the garment's lifespan for consistent protection season after season.

Rash guard fit and sizing

Long-sleeve rash guards should fit snug but not be restrictive. A close fit prevents water drag, eliminates fabric bunching that causes chafing, and maintains consistent protection.

You should move your arms through their full range of motion without pulling or binding. Sleeves should extend to your wrists without interfering with hand movement, preventing gaps in coverage when you reach or stretch.

The stretch in our zipper rash guards creates a snug fit that stays comfortable all day. Pair with men's swim trunks for complete coverage.

Care instructions for longevity

Rinse with fresh water immediately after each use to remove chlorine, salt, and contaminants.
Machine wash in cold water using mild detergent. Close all zippers before washing to prevent snags.
Avoid fabric softeners and bleach, which can reduce UPF protection and moisture-wicking properties.
Air dry when possible. If using a dryer, use the lowest heat setting.
Store in a cool, dry place away from direct sunlight when not in use.

Long-sleeve rash guards for men FAQ

Are long-sleeved rash guards better than short-sleeved ones?

Long-sleeve rash guards cover more skin, blocking UV rays on your forearms and wrists that short-sleeve versions miss. Water sports enthusiasts who spend hours in direct sunlight benefit from the extra coverage. Short sleeves are better for short exposure or when you want more ventilation.

Why do men wear rash guards?

Men wear rash guards to prevent sunburn and skin irritation. Our UPF 50+ fabric blocks harmful rays while the snug fit stops chafing from surfboards, sand, and saltwater. Rash guards also reduce drag in water compared to loose swim tops, making them popular for surfing and competitive swimming.

Are you supposed to wear anything under a rash guard?

Wear swim trunks or board shorts with your rash guard, but skip underwear or undershirts. The rash guard's flat seam construction and moisture-wicking fabric work best against bare skin. Adding layers underneath creates bulk and reduces the garment's performance benefits.

Do rash guards actually work?

Rash guards with UPF 50+ rating block 98% of UV radiation, much more than regular shirts. They prevent surf rash from board wax friction and protect skin against sunburn during extended water exposure. The lightweight design and quick-dry fabric maintain protection without restricting movement during aquatic adventures.

How long do rashguards last?

Quality surf rash guards last 2–3 years with regular use and proper care. Chlorine, saltwater, and sun exposure gradually break down fabrics over time. Rinse after each use, wash in cold water, and air dry to extend lifespan. Avoid fabric softeners, which reduce UV protection.
