Finntrail VIZARD Khaki 6608 UV Sun Shirt with Face Mask
A light summer long-sleeve shirt with UPF 50 protection and a built-in face mask that shields your skin from harmful sun and keeps mosquitoes away on a hot day outdoors. It is three layers of protection in one: the UPF 50 fabric blocks UV rays, the long sleeves cover your arms, and a built-in face mask with silicone inserts pulls up over your face when the sun or the bugs get too much. The quick-drying, breathable fabric with flat seams stays kind to your skin and keeps your body cool, while an antibacterial finish and mosquito-repellent technology keep it comfortable all day outdoors.
Who it is for
Made for summer outdoor use in the sun, when you need to protect your skin from UV rays, cover your face and keep mosquitoes off without carrying a separate mask or repellent.
- •For anglers and outdoor enthusiasts on a hot, sunny day.
- •For travel and hiking, when you spend long hours in the sun.
- •For sport and active rest by the water.
When it shines
Best on a hot, sunny day outdoors or on the water, when you spend long hours in the sun and want to cover your skin and face with a single garment: UPF 50 blocks UV rays, the built-in mask pulls up over your face when needed, and mosquito-repellent technology keeps the bites away.
Technical specs
Materials & technology
UPF 50 sun protection
The fabric blocks harmful UV rays and protects your skin from burning during long spells in the sun or on the water, while the long sleeves cover your arms as well. It is a summer protection layer, not a warm shirt.
Built-in face mask
A mask sewn to the collar, with silicone inserts, pulls up over your face when the sun or mosquitoes get too much, and stays at your neck when you do not need it. There is no separate mask or scarf to carry.
Breathable, protective fabric
The quick-drying, breathable fabric with flat seams stays kind to your skin and keeps your body cool. An antibacterial finish reduces odours, and mosquito-repellent technology keeps the bites away all day outdoors.
How it differs from a plain shirt in summer
Care
Wash cool on a gentle setting, without fabric softener or bleach, to keep the breathable and antibacterial finish. After a day outdoors, rinse out sweat or dirty water so the fabric lasts longer. Dry at room temperature, out of direct sun and away from radiators.
Frequently asked questions
Is this a warm, winter shirt?
No. This is a summer UV protection shirt. Its purpose is to protect your skin from the sun (UPF 50), cover your face with a built-in mask and keep mosquitoes off on a hot day. It gives no warmth; for the cold, choose a warm thermal layer.
How does UPF 50 protection work?
The fabric blocks harmful UV rays and protects your skin from sunburn during long spells outdoors or on the water. UPF 50 means a very high level of protection.
How does the built-in face mask work?
The mask is sewn to the collar and, with its silicone inserts, pulls up over your face when the sun or mosquitoes get too much. When you do not need it, you pull it down and it stays at your neck, so there is nothing separate to carry.
Does it protect against mosquitoes?
Yes. The fabric has mosquito-repellent technology, and the long sleeves with the built-in mask cover the exposed areas, so mosquitoes bite far less often.
Does it suit both men and women?
Yes. The cut is anatomical and unisex, so it suits both men and women. Choose your usual size; if you are between two, go up. If unsure, message us and we will help.

How to Choose the Correct FINNTRAIL Men’s Thermals Size
Choosing the correct FINNTRAIL thermal clothing size ensures comfort, freedom of movement, effective layering and proper protection from weather conditions. A size that is too small may restrict movement and feel tight around the chest or shoulders, while a size that is too large may reduce heat retention and overall fit.
The size chart shows body measurements, not garment measurements. FINNTRAIL gear is designed with extra room for comfort and movement, so sizing should be selected according to your body measurements.
Measure Your Chest Girth
Measure around the fullest part of your chest, keeping the measuring tape horizontal. Stand straight and keep the tape close to the body, but not tight.
How to measure: measure around the widest part of your chest while breathing naturally and keeping your body relaxed.This measurement is especially important when choosing jackets and the upper part of a suit.
Measure Your Waist and Hips
Measure your waist at the narrowest part or where you usually wear your pants. Measure your hips around the widest part.
Important: do not pull in your stomach and do not tighten the measuring tape too much. The gear should leave enough room for movement, base layers and comfortable sitting.If you are choosing a suit or pants, hip and waist measurements are just as important as height.
Measure Inseam and Sleeve Length
Inseam is measured from the crotch to the inside of the ankle. Sleeve length helps determine whether the jacket sleeves will properly cover your arms during active movement.
Recommendation: check these measurements if you are taller, have longer arms or legs, or are choosing between a standard and a longer size.How to Use the Size Chart
Measurement Description Height Body height in centimeters. Chest girth Chest circumference measured around the fullest part of the chest. Waist girth Waist circumference. Hips Hip circumference measured around the widest part of the hips. Inseam Inside leg length from crotch to ankle. Sleeve Sleeve length. First, choose the size according to the main girth measurements — chest, waist and hips. Then check whether the selected size matches your height, inseam and sleeve length.

S M L XLStandard sizes for men with average body proportions.
MLLonger size for taller users whose girths match size M but who need extra length.
SK MK LK XLKWider sizes for larger chest, waist or hip measurements.
XXL XXXLLarger sizes for taller users or broader body types.
If You Are Between Two Sizes
If your measurements fall between two sizes, choose according to how the gear will be used. Jackets and suits should leave enough room for base layers, while thermals should fit closer to the body without restricting movement.
- If you are choosing a jacket or suit, the larger size is usually the safer choice.
- If you are choosing thermal clothing, the fit should be close but not tight.
- If height matches one size but girths match another, prioritize girth measurements.
- If you will wear additional layers, leave more room.
Important: technical gear should not be too tight. Fabric under tension wears faster and may restrict membrane performance and freedom of movement.Recommendation Before Ordering
Before ordering a FINNTRAIL jacket, suit or thermal clothing, accurately measure your main body parameters. Take measurements while wearing a thin base layer or clothing similar to what you plan to wear under the gear.
Best result: provide your height, chest, waist and hip measurements. If possible, also include inseam and sleeve length.Summary
To choose the correct FINNTRAIL men’s jackets, suits or thermals size, the most important measurements are height, chest girth, waist girth, hips, inseam and sleeve length. A correctly selected size ensures comfort, layering ability, freedom of movement and effective protection for active use.

Membrane waterproofing and breathability
Membrane fabric is usually described using two numbers, often separated by a slash: waterproofness and breathability. The first number indicates waterproofness, the second indicates breathability.
?Waterproofing
This is a sliding scale measured in mm that shows how high a column of water you can suspend over the membrane before it starts to let moisture through.
Waterproof Rating Conditions 0–10,000 mm Light rain, dry snow, light pressure. 11,000–15,000 mm Moderate rain, average snow, light pressure. 16,000–20,000 mm Heavy rain, wet snow, some pressure. 20,000 mm+ Heavy rain, wet snow, high pressure. ?Breathability
This is the amount of moisture by weight that can pass through one square metre of fabric over a period of 24 hours. It is commonly measured in g/m²/24 hrs.
Breathability Rating Level of Breathability 0–5,000 g/m²/24 hrs Low – light exercise. 5,000–15,000 g/m²/24 hrs Medium – medium to high energy activity. 15,000 g/m²/24 hrs+ High – vigorous sustained activity.
