Description

Design details

What is the fill power of the down used in the Makalu jacket?
The Makalu down jacket is filled with a blend of 90% duck down and 10% feathers, with a fill power of 700 Cuin (IDFB standard). The jacket features a 3D-chambered construction to optimize the distribution of the down and improve thermal performance.
What is the recommended usage temperature for this down jacket?
This down jacket was tested in a thermal chamber on a mannequin wearing a long-sleeve synthetic t-shirt and a lightweight fleece, with simulated wind at 5 km/h. This test confirmed a comfort temperature of -27°C during moderate activity.
How many pockets does this down jacket have?
2 outer hand-warmer pockets. 2 outer chest pockets accessible when wearing a harness + 1 inner flap pocket to hold a phone. 2 inner mesh pockets to hold a flask or keep spare gloves warm.1 stuff sack for storing the jacket when not in use.
What is the RDS certification?
Products certified to the Responsible Down Standard contain down or feathers sourced from farms that meet strict animal welfare requirements. Certificate No. CB-CUC-1319850. Control Union Certification
What are the distinctive features of the hood?
The down hood is designed to be worn over a mountaineering helmet. The adjustment systems at the front and back of the hood ensure a secure fit.
What is the purpose of the reinforcements on the forearms?
The forearm is an area that is put under a great deal of strain during strenuous activities such as mountaineering. Adding a durable component helps to reduce the risk of abrasion and allows you to use it without worrying about snags or tears.
Is this jacket water-repellent or waterproof?
This down jacket has water-repellency. Water-repellency refers to a fabric’s capacity to allow water to run off its surface without being absorbed. This means the textile doesn’t become waterlogged and stays warm. Water-repellency is achieved through a PFC-free treatment applied to the outer surface of the fabric, which may wear off with use. We advise you to reactivate it after each wash. In wet weather, we advise you to wear a waterproof jacket over this down jacket.
How do you maintain your Makalu down jacket?
Worn throughout the winter, your down jacket will certainly need washing. But don’t wash it too often, as there is a risk that its thermal and repellent properties will deteriorate. Machine wash at 30°C with 2 or 3 tennis balls and a detergent designed for down. Select a gentle spin cycle. Tumble-dry it with 2 or 3 tennis balls, and repeat the process several times until it is completely dry. Or a dry-cleaning service for care.
