About Haglöfs Alper Proof Jacket Men – Men's Ski Jackets
The Haglöfs Alper Proof Jacket is a ski jacket for those who want a truly reliable shell jacket, whether you're on the slopes or off-piste. It's made from a 3-layer PROOF™ Pro shell with a waterproof membrane of 20,000 mm and breathability of the same amount. This means you stay dry in snowstorms, while the jacket vents excess heat when you're highly active.
The hood is adjustable and fits well over a helmet. Under the arms are zippered ventilation openings, so you can easily regulate the temperature. At the front, you'll find double hand pockets, a chest pocket, and a dedicated ski pass pocket on the sleeve.
Inside, there's a flexible snow skirt that prevents powder snow from getting in. The Haglöfs Alper Proof Jacket closes with a water-repellent two-way zipper and has a drawstring at the hem, allowing you to adjust the fit. The sleeves are pre-shaped and can be adjusted with Velcro.
The material is not only technical – it's also sustainable. The jacket is made from recycled polyester and polyamide, with PFAS-free DWR impregnation and Bluesign-approved fabrics. This means it's a better choice for both you and the environment.

Size & fit
Measure your chest at its widest point and compare with the size chart in the size guide. If you are between two sizes, go for the smaller one if you want a snugger fit, or the larger one if you want room for more layers underneath. Not sure? Give us a call and we will help you.
Care
Wash at 30° with a liquid detergent for technical garments — never use fabric softener or bleach. Tumble dry on low heat or iron at a low temperature to reactivate the water-repellent treatment. Reproof when water stops beading on the surface, usually after 15–20 washes.

Choosing a shell jacket
Waterproofing and breathability
Waterproofing is measured in millimetres (hydrostatic head) and describes how much water pressure the fabric can withstand before it leaks. 10,000 mm handles normal precipitation, while 20,000 mm handles wet snow and rain all day long — even where you sit and press against the fabric on the chairlift. Breathability is measured in grams of moisture per square metre per 24 hours and determines how much sweat is transported out. You want high numbers for both; a waterproof fabric without breathability will just make you wet from the inside instead.
The layering principle
The shell is the outer layer and is not meant to be warm in itself. The warmth comes from the mid-layer — merino wool or fleece — and closest to the skin is a thin layer that moves moisture away from your body. The advantage of a pure shell over a padded jacket is that you can regulate your warmth to suit the weather and your pace, instead of being locked into one level of insulation. That is why the shell is cut with room for a mid-layer, and why it can feel roomy when you try it on without one.
The details that make the difference
A powder skirt at the waist keeps snow out when you fall. Underarm vents are the quickest way to regulate your temperature without taking anything off. The hood should be adjustable with one hand and fit over a helmet without blocking your view. Taped seams are essential, because a waterproof fabric will leak through the seams if they are not sealed. The pockets should be placed so they work with a hip belt on and a lift pass in the sleeve.
Size and fit
The jacket is cut with room for insulation. If you are between two sizes and ski without a thick mid-layer, go for the smaller one. If you want room for a thicker sweater, or do a lot of ski touring where you need freedom of movement, go for the larger one. The sleeves should reach past your wrists when you stretch your arms forward.
How to keep your jacket waterproof
A shell rarely stops being waterproof — it stops repelling water on the surface. When the fabric turns dark and heavy with moisture, it is the outer water-repellent treatment that has worn off, not the membrane. Wash the jacket with a detergent made for shell garments, tumble dry it on low heat or iron it with a cloth in between to reactivate the treatment, and reproof when needed. A jacket that is looked after stays waterproof season after season.
