## Description

High-end down jacket made from the high-quality goose down with a fill power of 900 cuin and a hydrophobic treatment, and from ultralight and durable Pertex® Quantum fabric weighing 28 g/m2. The Cumulus Mountlite Jacket will be useful for anyone who needs lightweight and reliable gear for winter conditions.

## What is specific about the product?

Packable and well-designed ultralight down jacket with hydrophobic down for year-round use.

## Materials

Pertex® Quantum 28 g/m2 material (10-denier ripstop, 100% nylon) has been used on both the outer and inner sides, which has good durability, maintains good breathability, low weight, and packability. The outer side of the fabric is treated with a **durable water-repellent (DWR) finish**.

A great performance is ensured by **180 grams of goose down with a fill power of 900 cuin**. During outdoor activities, your down jacket is exposed to an increased risk of getting wet or damp, which the manufacturer considered from the very beginning and filled the jacket with **down that has a hydrophobic treatment**, so it does not lose its loft immediately upon contact with water.

The down jacket can be packed into an **outer pocket** with a volume of 2,5 liters (dimensions 17 x 14 cm).

The total weight in size M is 390 grams. The package also includes a **small transport sack**.

### High collar

A sufficiently high collar that protects against the cold. The zipper end is covered with a protective flap to prevent chin chafing.

### Cuff sleeves

Thanks to the elastic cuffs, your sleeves won't keep riding up while you move.

### Two zipper sliders

Using two zippers (3 mm YKK® zipper), you can easily regulate your body temperature. It is also easier to handle the climbing harness.

### Three outer pockets

There are two outer pockets on the sides and one on the chest.

### Adjustable hood

You can adjust the hood with a elastic drawcord as needed. It won't fall into your eyes here. It's large enough to fit a helmet as well.

### Technical cut

The bottom hem of the jacket is elongated and is equipped with a drawstring cuff. This prevents the down jacket from riding up and leaving the back exposed.
