Men's Sun Protection Long Sleeve Half-Zip T-Shirt | Dark Gray / S 100400110263130

How to measure

To get the best fit, measure either your body or a similar garment that fits you well. Use a soft measuring tape, keep the tape parallel to the floor and relaxed (not pulled tight).

Body measurements (wear light layers)

• Chest: Measure around the fullest part of the chest, under the arms and across the shoulder blades. Keep tape level.
• Waist: Measure around the natural waist (narrowest point), usually just above the belly button.
• Hips: Measure around the fullest part of the hips and seat.
• Shoulder width: Measure from the outside edge of one shoulder to the other across the back.
• Sleeve length: Measure from the center back of the neck (high point shoulder) down along the shoulder and arm to the wrist. For garment-only measurement, measure from the shoulder seam to the cuff.
• Body length: Measure from the high point of the shoulder (where the shoulder meets the base of the neck) straight down to the hem.
• Wrist / Cuff circumference: Measure around the point where the sleeve rests at the wrist.

Measuring a garment (recommended for most accurate fit)

• Lay the shirt flat on a smooth surface and smooth out wrinkles (do not stretch).
• Half‑chest: Measure 1" (2.5 cm) below the armpit across the front from seam to seam. Multiply this number by 2 for full chest circumference.
• Shoulder width: Measure seam to seam across the top of the back.
• Sleeve length: Measure from the shoulder seam to the end of the cuff.
• Body length: Measure from the high point shoulder to the bottom hem.
• Hem width: Measure across the bottom edge and multiply by 2 for circumference.

Conversion: 1 in = 2.54 cm. If you are between sizes and prefer layering or a relaxed look, size up one. For a closer athletic fit, choose your usual size.

Materials & features

Exact fabric composition can vary by color or season—always check the garment tag. Typical materials and technical features for a sun‑protection half‑zip tee include:

• Main fabric: Lightweight performance knit (commonly high‑density polyester or a polyester/elastane blend). Polyester gives quick‑drying and moisture‑wicking properties; elastane/spandex adds stretch and recovery.
• Sun protection: Built‑in UPF (often UPF 30–50+) to block UVA/UVB when properly worn.
• Moisture management: Moisture‑wicking and fast‑drying finish keeps skin comfortable during activity.
• Stretch & comfort: Four‑way mechanical or blended stretch for freedom of movement (ideal for outdoor sports and layering).
• Odor & durability: Some variants include antimicrobial/odor‑control finishes and chlorine‑resistant treatments for pool/beach use.
• Trim & hardware: Low‑profile half‑zip (often YKK or equivalent), zipper garage at the collar to protect skin, flatlock seams to reduce chafing.
• Sustainability options: Many styles offer recycled polyester or low-impact dyeing—check the product label.

Note: finishes like UPF, antimicrobial or chlorine resistance can fade over time and with heavy washing—refer to the care label for longevity tips.

Model & fit

Reference example used for imagery and sizing guidance:

• Model height: 6'1" (185 cm)
• Model chest: 38" (97 cm)
• Wearing size: Medium
• Fit description: Modern/athletic fit — trim through the chest and sleeves with enough room for a base layer. If you prefer room for thicker layers or a relaxed silhouette, select the next size up.

If the product has multiple fit options (slim, regular, relaxed) check the specific fit callout on the product page.

Care Guide (to keep it lovely longer)

• Turn the garment inside out and zip the half‑zip before washing to protect the zipper and fabric.
• Machine wash cold or warm on a gentle cycle with similar colors. Use a mild detergent.
• Avoid bleach and fabric softeners (softeners can reduce moisture‑wicking and UPF performance).
• For sunscreen or oil stains: pre‑treat with a mild stain remover and wash promptly. For stubborn sunscreen, soak briefly before washing.
• Rinse after exposure to saltwater or pool chlorine to remove residues.
• Air dry flat or hang to dry for best shape and to protect finishes. If using a dryer, tumble dry low and remove promptly.
• Do not iron prints, logos or the zipper. If ironing is necessary, use low heat and press on the reverse side with a cloth between iron and fabric.
• Do not dry clean unless the care label specifically allows it.
• Store folded or hung in a cool, dry place away from prolonged direct sunlight to avoid color fading.
• To reduce microfibre shedding: wash in a full load, use a Guppyfriend bag or a microfiber filter if available.

Style tips

• Sun & water days: Wear it zipped up with swim trunks and sandals for maximum UV coverage at the beach or on the boat.
• Hiking & active: Pair with quick‑dry hiking shorts or pants and trail shoes. Leave the zip slightly open for airflow on climbs.
• Casual & travel: Combine with chinos or joggers and low‑profile sneakers for a smart‑casual active look—zip down to show a tee beneath.
• Layering: Use as a mid‑layer under a windbreaker or light shell. Its low bulk makes it ideal under jackets without adding weight.
• Color pairing: Neutral tones (navy, grey, black, olive) pair easily with brighter shorts/pants; brighter tops work well with muted bottoms.
• Half‑zip styling: Fully zipped for sun/wind protection or a neat collar; half‑zipped or open for a relaxed, layered appearance and better ventilation.
• Accessories: Add a wide‑brim hat, sunglasses and a water‑resistant watch for a functional outdoor look.

Quick tip: for a streamlined active outfit, match the sleeve color to your shoes or hat for a cohesive look.
