Summary — Size guide Helly Hansen
Alpinstore return tips — Helly Hansen
- Helly Hansen generally runs large — especially for jackets and pants. The official HH site states "This product fits normally" on product pages, but user returns and several retailer guides specify that HH outdoor cuts are often generous to allow for layering. For ski jackets and shells, if you wear layers underneath, your usual size is fine. If the jacket is worn alone, go down a size.
- Technical ski clothing (jackets, suits) : designed for layering. Allow space for a mid-layer fleece or a thin down jacket under the jacket. If you only wear a base layer, go down a size.
- LIFA® and Merino base layers : close-fitting cuts. Usual size. Base layers should be fitted to be effective.
- Helly Hansen hiking shoes : the official site states "fits normally, take your usual size". Verified on Cascade HT product pages. +1/2 size if thick socks are planned.
- Winter boots (Garibaldi, Varanger, Fremont) : thick Primaloft lining. Usual size. If you wear thick ski socks, go up a size.

7. Après-ski & winter boots Helly Hansen
Winter boots HH size tips (anti-return)
- Usual size for most models : the Garibaldi V3, Fremont, and Varanger Primaloft boots fit normally (official HH message). If you wear thin or normal socks, take your usual size.
- With thick socks : go up half a size or even a full size. The Primaloft lining takes up space. The high après-ski boots (Garibaldi) are more generous than the low models.
- Removable liner : several HH models (Varanger, Garibaldi Puffy) have a removable inner liner. When new, it may seem snug — it will soften with wear.
- Women's après-ski (Isolabella, Alma) : usual size. Lighter and more stylish models than expedition boots. Thin Primaloft lining.
The EU/UK/US size charts for HH winter boots are identical to the hiking charts above. Use the same chart (Men or Women depending on the model). Some unisex models use men's sizes.

9. FAQ — Helly Hansen Size Guide
Does Helly Hansen run large or normal ?
The official HH site states "fits normally" on product pages. In practice, HH outdoor and ski cuts are designed for layering and are often generous. For ski jackets and shells intended to be worn with multiple layers, your usual size is fine. For more fitted jackets or mid-layers, some users go down a size. LIFA and Merino base layers fit normally — fitted cuts as intended. If in doubt, check the specific mention on the official HH product page (hellyhansen.com).
What is the difference between Helly Tech® and Gore-Tex on HH shoes ?
Helly Tech® is Helly Hansen's proprietary waterproof membrane, used in the Cascade range. It offers excellent waterproofing (20,000 mm+) and good breathability for versatile hiking. Gore-Tex is used in the Trollveggen models, positioned in the upper technical segment. Both technologies are proven; the performance difference is noticeable especially for very intensive or long-duration uses. The size advice is identical for both ranges.
How to care for my Garibaldi or Varanger HH boots ?
For boots with removable Primaloft lining: remove the inner liner after each use to let it dry in the open air (no tumble dryer). The outer shaft (rubber or nylon) can be cleaned with a damp cloth. To reactivate the water-repellent on textile models, wash for an hour at 40°C in the machine and then dry at low temperature. Do not use fabric softener. HH officially advises against abrasive cleaning products on Helly Tech membranes.
Which hiking range to choose between Cascade and Trollveggen ?
The Cascade range (Helly Tech, low or mid-high) is ideal for versatile hiking, marked trails, and trekking weekends. Lighter, more breathable, and more affordable. The Trollveggen range (Gore-Tex, high shaft) is designed for technical terrains, long mountain outings, and demanding conditions. Stiffer, heavier, more protective. The size advice is identical for both ranges ("fits normally", message hellyhansen.com).
Sources: official Helly Hansen guide (hellyhansen.com/fr_fr/size-chart), official HH product pages (hellyhansen.com — Cascade HT, Garibaldi V3, Varanger, Trollveggen). The measurements are body measurements. Official HH message on shoes: "Fits normally. Take your usual size." Winter boots with thick lining: go up a size if thick socks. Data verified in June 2025.
