Finntrail NITRO DarkGrey 4603 Softshell Pants
SoftShell membrane fabric
Wicks excess moisture and blocks wind
DWR coating
Protects against rain, water and dirt
Anatomical leg cut
Comfort and freedom of movement
Versatile
Wear as an outer or insulating layer
Stretchy softshell pants that block wind and light rain while keeping you warm with a fleece lining. A 3-layer softshell with a breathable membrane and inner fleece: protection from wind and light rain that breathes, stretches with you and never restricts movement in changeable weather.
Who they are for
Made for the hiker, traveller and angler who wants a light, warm layer with full freedom of movement on cool, windy days.
- •Hikes and leisure when it is windy and drizzling but not pouring.
- •Fishing and the outdoors in cool autumn and spring, when warmth and free movement matter.
- •Layering: wear on their own or under a rain jacket when you need warmth and stretch.
When they shine
They perform best on cool, windy autumn and spring days, when plain trousers feel cold and stiff but a full rain kit is overkill. The softshell blocks wind and drizzle, breathes and warms you with its fleece lining.
Technical specs
Materials & technology
3-layer softshell
A three-layer fabric: an outer protective face, a breathable membrane and an inner fleece. Together they block wind and moisture while keeping you warm.
Breathable membrane
Holds off wind and light rain from outside yet lets sweat vapour out (10,000 g/m²/24h), so you don’t get clammy inside.
Inner fleece
A soft fleece lining traps warmth and wicks moisture away from the body, so cool weather feels comfortable.
Stretch fabric
The elastic softshell moves with you: crouch, climb and stride freely while the fabric wears less.
Water-repellent finish (DWR)
A thin water-repellent coating: drizzle beads and rolls off, the fabric wets out less and dries faster. Renew it with an impregnation spray.
How they differ from plain trousers
Care
Wash up to 30 °C with a detergent made for fleece and softshell (Mountval Polar Wash), without softener or bleach. When water stops beading, restore the water repellency with an impregnator (Mountval Textile Shield). Dry at room temperature, not on a radiator. Do not iron hot, so the fabric finish stays intact.
Frequently asked questions
Are softshell pants waterproof in the rain?
They repel wind and light rain or drizzle (water resistance 7,000 mm), but they are not a fully waterproof layer. In prolonged heavy rain, put on membrane rain pants or wear the NITRO under a rain jacket.
Are they warm?
Yes. The inner fleece layer keeps you warm on cool, windy days, while the softshell construction blocks the wind, so you stay warm without bulky insulation.
Do they breathe, or will I sweat?
They breathe: breathability is 10,000 g/m²/24h. The membrane lets sweat vapour escape, so you stay dry inside even when active.
Is the fabric stretchy and unrestrictive?
Yes. The softshell is elastic and the cut is ergonomic, so the pants stretch with you when crouching, climbing or striding. The elastic waistband and inner calf adjustment fine-tune the fit.
Do they work under another jacket or as a layer?
Yes. Wear the NITRO pants on their own or as a warm mid layer under a rain kit. They pair with the NITRO jacket from the same line.

How to Choose the Correct FINNTRAIL Men's Pants Size
Choosing the correct pants size ensures comfort, freedom of movement and optimal performance during outdoor activities. Pants that are too small may feel tight around the waist or hips and restrict movement, while pants that are too large may slide down, interfere with walking and reduce overall comfort.
The FINNTRAIL size chart shows body measurements, not garment measurements. FINNTRAIL pants are designed with additional room for mobility, comfort and layering when needed.
Measure Your Height
Height is one of the key measurements when choosing men's pants, as it helps determine overall fit and leg length. Measure your height while standing upright without shoes.
How to measure: stand straight with your feet together and measure from the floor to the top of your head.Measure Your Waist
Measure your waist at its narrowest point or where you normally wear your pants. The measuring tape should fit comfortably around your body without being too tight.
Important: do not suck in your stomach or tighten the tape excessively. Pants should allow comfortable movement, sitting and layering.Measure Your Hips
Measure around the fullest part of your hips. This measurement is particularly important because pants should allow unrestricted movement while walking, climbing, sitting or engaging in outdoor activities.
Recommendation: if your hip measurement falls into a larger size than your waist measurement, choose the size according to your hips.Measure Your Inseam
Inseam is measured from the crotch down to the inside of the ankle. This measurement helps determine whether the pants will provide the proper leg length for your height.
If you plan to wear taller boots or use the pants for active outdoor activities, ensuring the correct inseam length is especially important.
How to Use the Size Chart
Measurement Description Height Body height in centimeters. Waist Waist circumference. Hips Hip circumference measured around the fullest part of the hips. Inseam Inside leg length from crotch to ankle. Start by checking your waist and hip measurements. Then confirm that the selected size matches your height and inseam. If one measurement falls into a larger size category, it is generally recommended to choose the larger size.

S M L XLStandard sizes for men with average body proportions.
MLExtended length size for taller users whose waist and hip measurements correspond to size M.
SK MK LK XLKWider sizes designed for larger waist and hip measurements.
XXL XXXLLarger sizes for taller or broader body types.
If You Are Between Two Sizes
If your measurements fall between two sizes, choose according to how the pants will be used. For active outdoor use, the fabric should never feel tight across the waist, hips or knees.
- If your hips fall into a larger size category than your waist, choose according to your hip measurement.
- If you plan to wear thermal layers underneath, allow extra room.
- If you are taller than average, pay special attention to inseam length.
- For active use, avoid choosing pants that fit too tightly.
Important: technical pants should not be overly tight. Fabric under constant tension wears faster, restricts movement and reduces overall comfort.Recommendation Before Ordering
Before ordering FINNTRAIL men's pants, measure your height, waist, hips and inseam accurately. Take measurements while wearing a thin base layer or clothing similar to what you plan to wear underneath the pants.
Best results: provide your height, waist circumference, hip circumference and inseam measurement. These measurements allow the most accurate FINNTRAIL size recommendation.Summary
To choose the correct FINNTRAIL men's pants size, the most important measurements are height, waist circumference, hip circumference and inseam length. The correct size ensures comfort, freedom of movement, effective layering and long-lasting performance.

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.
