DRILITE® Loft 20 D – water and wind resistant

DRILITE® Loft 20 D is a strong and lightweight waterproof outer material with a PU coating. It is highly breathable and resistant to water and wind. The surface also has a DWR water-repellent finish, which further helps to keep the down dry even in wet conditions. The down is thus protected from moisture and therefore from losing its thermal insulation properties. Thanks to its water resistance and low weight, the down maintains a high loft for maximum thermal insulation in all conditions.



● Lightweight material – 36 g/m2.

● Highly breathable.

● Windproof.

● Water-resistant – 1,500 mm.

● Made in Japan.



High-quality duck down with 700+ fill power

Very high-quality duck down from China contains at least 90% down, has a minimum fill power of 700 cuin, and meets the ethical DOWN CODEX®. The down is processed without chemical treatment. This reduces dust mites and their living environment, which is appreciated by allergy sufferers. The down retains its important natural oils and loft, is highly compressible, provides excellent insulation, and has low weight.



● 37 g of down.

● Minimum fill power 700+ cuin.

● Down-to-feather ratio 90:10.

DOWN CODEX® – a symbol of ethical approach to animal husbandry

DOWN CODEX® is a certification of the origin of down, its quality, and an ethical and ecological approach to animal husbandry. Farms from which Mountain Equipment purchases down are inspected annually.



● Each down product has a unique code to trace the origin of the down and its parameters.

● In Mountain Equipment products, down is always a by-product of meat or egg production.



Skirt with waterproof DRILITE® Loft 20 D material

The outer fabric of the FROSTLINE WOMEN'S SKIRT is made of DRILITE® Loft 20 D polyamide material, which protects the down from moisture and thus from losing its thermal insulation properties. At the same time, this fabric, thanks to its softness and lightness, allows for maximum loft (puffiness) of the down, which significantly enhances its thermal insulation properties.



Easy to put on and take off

The FROSTLINE WOMEN'S SKIRT features a two-way full-length side zip, allowing you to quickly and easily put it on or take it off at any time without needing to remove your boots or bindings. It is an ideal companion for demanding winter hikes where minimal weight and maximum performance are required. Whether at the summit or at any point during the ascent, you can easily put on the skirt, and it will warm you up instantly.



It is an ideal companion on frosty, windy days, often worn during the ascent to the summit. Thanks to the DRILITE® Loft outer material, it can also be used effectively as an outer layer. It is wind and water-resistant, so you don't have to worry about wet snow or drizzle.
