More informationWhat Is an Insulated Ski Jacket and What Are the Options?
An insulated ski jacket is essential for anyone seeking warmth and comfort while skiing or snowboarding. The insulation helps maintain your body temperature, even in the harshest conditions. There are different types of insulation, each with its own advantages. In this guide, we explain the differences so you can make the perfect choice.
Down Insulation: Lightweight and Extremely Warm
A jacket insulated with down is the ideal choice for those looking for maximum warmth without sacrificing comfort. Down provides excellent insulation and is very lightweight, making it perfect for cold, dry conditions. However, keep in mind that down performs less well in wet conditions unless the jacket has been specially treated to resist moisture.
Wool Insulation: Natural and Breathable
Jackets with wool insulation offer a natural alternative. Wool is not only warm but also breathable and retains heat even when damp. This option is ideal for those who prefer natural materials and comfort in varying weather conditions.
Synthetic Insulation: Versatile and Low-Maintenance
Synthetic insulation, such as PrimaLoft or Thinsulate, offers excellent warmth and performs well in wet conditions. This option is often slightly heavier than down but dries quickly and is easier to care for. It’s ideal for active winter sports enthusiasts who value versatility and affordability.
Why Choose an Insulated Ski Jacket?
-
Optimal Warmth: Protect yourself against extreme cold.
-
Comfort During Activity: Maintain your freedom of movement without sacrificing insulation.
-
Suitable for Various Weather Conditions: Whether you're skiing in powder snow or braving a cold wind, an insulated jacket adapts to your needs.
Which Insulation Suits You Best?
The right insulation depends on your personal preferences and the conditions in which you’ll wear the jacket. Looking for ultimate warmth and comfort? Go for down. Need a versatile, low-maintenance option? Consider synthetic materials. Or choose wool for a natural feel.

STEP BY STEP GUIDE:
1. Check your items
√ Has the return period of 14 days after receipt not expired
√ Is the yellow return label (in the case of outerwear and trousers) and all price tags still attached?
√ Is the article unworn and therefore not dirty, damaged or creased?
2. Submit your return online

You can also choose another carrier outside the portal. We always advise you to send the parcel insured. The DPD label via the portal insures your parcel up to €500.
3. Pack your return
√ Fold the items neatly and close all zips and buttons. Because of the technical materials it is important not to cause serious creases and wrinkles, as these can damage the product.
Then pack the items back in their original packaging and put them in the shipping bag or box. Another bag or box is also fine, as long as it is sturdy so that it arrives undamaged

- 30,000 mm water column, fully taped seams
- 60 g PrimaLoft Gold Eco in body, 40 g in sleeves
- High-reach arms and ergonomic elbow for mobility
- Light 60/40 g fill: needs a midlayer in deep cold
- Fixed insulation, too warm for ski touring climbs
- Insulated: less versatile than a shell in spring
The Mountain Studio All Mountain Stretch Jacket S-1 is a men's insulated ski jacket for resort skiing and snowboarding. It is built on the brand's ALP-3 3-layer stretch membrane, rated 30,000 mm water column and 30,000 g/m²/24h breathability. What sets it apart is light PrimaLoft Gold Eco insulation, 60 g in the body and 40 g in the sleeves, combined with a stretch outer fabric and a high-reach arm construction.
Who is the All Mountain Stretch Jacket S-1 for?
The All Mountain Stretch Jacket S-1 is for resort skiers and snowboarders who want some extra warmth on cold mid-winter days, including at high-altitude resorts, without giving up freedom of movement. It is not built for ski touring or other sustained uphill effort, because the insulation is fixed and cannot be removed for the climb. On mild spring days an uninsulated shell is the more versatile choice. Climbing and technical mountaineering are outside its design.
How warm and waterproof is the All Mountain Stretch Jacket S-1?
The ALP-3 membrane of this insulated ski jacket is rated 30,000 mm water column and 30,000 g/m²/24h breathability, with fully taped seams and a PFAS-free DWR on the outer fabric. Warmth comes from 60 g PrimaLoft Gold Eco in the body and 40 g in the sleeves. That is light insulation: The Mountain Studio describes it as just warm enough to take the edge off on cold days. In very cold conditions, wear a warm midlayer underneath.
Which size should I choose in the All Mountain Stretch Jacket S-1?
The All Mountain Stretch Jacket S-1 uses a 40 denier outer fabric with 15% spandex, a high-reach arm construction and an ergonomic elbow shape, so the jacket follows your movements. The signature sidecut hem and cuffs, a snow skirt and a large helmet-compatible hood shape the fit. The model is 175 cm tall and wears size M. Compare your chest measurement with the size chart on this page, keeping in mind the midlayer you plan to wear underneath.
How is the ALP-3 3-layer construction of the All Mountain Stretch Jacket S-1 built?
The All Mountain Stretch Jacket S-1 from The Mountain Studio uses ALP-3, the brand's own hydrophilic membrane. Hydrophilic means non-porous: the membrane has no pores for water to pass through, and water vapour moves through the material itself. In this jacket ALP-3 forms a 3-layer construction with a 40 denier outer fabric of 85% nylon and 15% spandex, so the whole shell stretches. Every seam is fully taped and the zippers are YKK AquaGuard. Inside, PrimaLoft Gold Eco synthetic insulation with stretch is zoned: 60 g in the body, where you lose most heat, and 40 g in the sleeves, where less bulk keeps your arms free to move.
How does the All Mountain Stretch Jacket S-1 work on a resort ski day?
On the piste, the All Mountain Stretch Jacket S-1 is set up for lift-served skiing and snowboarding. The snow skirt keeps powder out when you fall or ride through deeper snow at the side of the run. The storm hood fits over a helmet, has an integrated visor and adjusts fully with a draw cord. A ski pass pocket on the sleeve lets you pass the gates without opening the jacket. Two chest pockets, two hand pockets and inside pocket compartments give room for phone, goggles cloth and gloves liners. The high-reach arm construction and ergonomic elbow shape stop the jacket from riding up when you lift your arms on a chairlift bar or pole plant.
Where does the All Mountain Stretch Jacket S-1 reach its limits?
The insulation in the All Mountain Stretch Jacket S-1 is built in, which makes this ski jacket less adaptable than a shell with a separate midlayer when temperatures or effort levels change during the day. For ski touring and long uphill sections the fixed PrimaLoft Gold Eco fill cannot be taken off, so a shell is the better tool. On very cold days the 60 g body and 40 g sleeve insulation needs a warm midlayer underneath, and on mild spring days an uninsulated shell is more versatile. Climbing and technical mountaineering are outside the design of this resort jacket.
What is the All Mountain Stretch Jacket S-1 made of, and how do you wash it?
The outer fabric of the All Mountain Stretch Jacket S-1 is 40 denier, 85% nylon and 15% spandex, finished with a PFAS-free DWR treatment and laminated to the 3-layer ALP-3 membrane. Wash the jacket inside out and separately, with all fasteners closed, using a mild detergent only. Do not use bleach or fabric softener, and do not dry clean it. Tumble dry at low heat. A repair kit is included with the jacket, and The Mountain Studio also offers its own PFAS-free DWR spray, Hightec Proof, to refresh the water-repellent finish.
Which environmental facts apply to the All Mountain Stretch Jacket S-1?
The outer fabric of the All Mountain Stretch Jacket S-1 carries a PFAS-free DWR treatment. The Mountain Studio has phased out PFAS from its line. The brand also runs a repair service, so a damaged jacket can be fixed rather than replaced.
