Finntrail BOOST Graphite 2026 Insulated Coat
The Finntrail BOOST Graphite 2026 is a warm long coat with Thermalrate® insulation and a HARD-TEX® membrane, built to be worn over your gear and keep you warm down to -30 °C. It is the new BOOST version in a plain graphite fabric. An extended back, a removable hood, a heavy-duty two-way zipper with a magnetic storm flap and fully taped seams protect you from cold, wind and snow during pit stops, competitions and long trips.
Who it is for
Made for snowmobile and ATV riders, anglers and anyone who spends long hours outside in the cold. The manufacturer designed BOOST for active riding, competitions, pit stops and extended trips in freezing conditions.
- •Pit stops and breaks while riding: throw the coat over your suit and protective gear so you don’t cool down while standing.
- •Competitions, training and ice fishing, when you spend a lot of time in one place and the temperature drops to -30 °C.
- •Everyday wear in hard frost, if you choose a coat 1 or 2 sizes smaller (see the FAQ on sizing).
When it shines
It shines in deep winter, when you stand or wait: at the track, in the pits, on the ice or at a trip stop. Where a jacket is enough while moving, but the cold catches up within minutes once you stop.
Technical specs
Materials & technology
HARD-TEX® 2.5-layer membrane
A microporous membrane that stops water from outside yet lets sweat vapour escape: 10,000 mm water resistance and 8,000 g/m²/24h breathability.
Thermalrate® insulation
Thin, effective insulation mapped to body zones: 250 g/m² in the body, 200 g/m² in the sleeves and hood, 150 g/m² in the collar. Holds warmth down to -30 °C.
Microfleece lining inserts
A branded lining with moisture-wicking microfleece inserts: your skin stays drier when you stand still after riding.
DWR finish
A thin water-repellent finish on the outer fabric: snow and sleet roll off and the fabric wets out less.
3M™ reflective elements
Reflect light back toward its source, so you are easier to see at dusk and in the dark.
How it differs from BOOST 2016
Care
Wash up to 30 °C with a dedicated membrane wash (e.g. Mountval Wash & Care), without softener or bleach. Restore the water repellency (DWR) with Mountval Waterproofing Refresher. Dry naturally, not on a radiator. Repair minor membrane damage with a dedicated adhesive (Aquaseal / Aquasure) on a clean, dry surface.
Frequently asked questions
How does the Finntrail BOOST Graphite 2026 differ from BOOST 2016?
According to the manufacturer, the main difference is the colour. BOOST 2016 had several colour blocks (graphite with yellow or orange), while BOOST Graphite 2026 is plain graphite. The membrane, insulation and details are the same.
Which size should I choose?
The Finntrail BOOST Graphite 2026 has a relaxed fit so it goes over a riding suit and protective gear. If you will wear it over such gear, take your usual size. For everyday wear, the manufacturer recommends going 1 or 2 sizes smaller.
Down to what temperature does it keep you warm?
The coat is designed for wear down to -30 °C. Thermalrate® insulation is 250 g/m² in the body, 200 g/m² in the sleeves and hood and 150 g/m² in the collar. The lining has moisture-wicking microfleece inserts in key areas.
Does it protect from snow, sleet and wind?
Yes. The HARD-TEX® 2.5-layer membrane with 10,000 mm water resistance, fully taped seams, a DWR finish and a double storm flap with magnets and snaps keep snow, moisture and wind out. 8,000 g/m²/24h breathability lets sweat vapour escape.
What pockets and details does it have?
Two zippered chest pockets with lens-wiping material, one zippered internal pocket and one mesh pocket, plus a D-ring for gear. The removable hood adjusts in two directions, the outer cuffs are adjustable and the inner Lycra cuffs have thumbholes.
Who is the Finntrail BOOST Graphite 2026 not for?
It is too warm and too long for active hiking or skiing: BOOST is made for standing, waiting and riding in the cold. For wet autumn weather without frost, choose a non-insulated membrane jacket.

How to Choose the Correct FINNTRAIL Men’s Jackets Size
Choosing the correct FINNTRAIL jacket 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.
