What are the features of the MT900 0°C Down sleeping bag?
The hood fits around your head with the drawstrings and the anti-cold flap along the zip prevents heat loss.
A YKK two-way zip with an anti-jam system ensures good ventilation.
An inside zip pocket allows you to store your small items.
Two loops at the bottom of the sleeping bag allow you to hang it up to air or dry.
Comes with a perforated fabric storage bag.
What is the loft of the down used in the MT900 0°C Down sleeping bag?
For the topside of the bag, we use 800 CUIN certified duck down (260 g in size L).
For the underside, we have opted for 700cuin recycled down (235g in size L).
In both cases, we use a blend of 90% duck down and 10% feathers.
The down is spread over 4cm-high compartments, separated by mesh partitions positioned in a Z-shape to prevent the formation of thermal bridges.
What are recycled feathers?
Using recycled feathers involves using a mixture of down and feathers from products that cannot be reused. This limits the use of new resources by recycling existing materials that would otherwise be discarded. The quality of the filling is checked through lab tests to make sure it maintains its technical properties and keeps you warm.
What is comfort temperature?
We display the comfort temperatures that are determined by an independent lab (AITEX) on all our sleeping bags, in accordance with the international standard ISO 23537-1: 2022.
Comfort temperature is the minimum temperature at which an average person (female, 25 years old, 60 kg, 1.60 m) feels comfortable and not cold when they are in a relaxed position.
Choose your sleeping bag accordingly.
What is the comfort limit temperature?
This is the temperature at which an average person (male, 25 years old, 70 kg, 1.73 m) can sleep curled up without really feeling the cold. For your information, the extreme temperature indicates the limit at which a person can survive for six hours. This is a safety measure, not a comfort measure.
Which mattress should I use this sleeping bag with?
We recommend using a mattress with an R-value of 4.8. Below this value, the thermal performance of your sleeping bag will be reduced.
What are the weight and dimensions of the MT900 0°C sleeping bag?

How resistant is the fabric used in the MT900 0°C down sleeping bag?
The exterior of the bag is made from 100% polyamide 27 g/m² 10 denier fabric with 30 denier ripstop reinforcement. This fabric can withstand 80,000 abrasion cycles.
Resistance is calculated using the Martindale test (ISO 12947-2 standard), which involves rubbing the fabric against another material to determine the product's wear limits.
The inner lining is made from 100% polyamide 35 g/m² 20 denier fabric.
How is the material used in this sleeping bag manufactured?
No PFAS treatments have been intentionally added to this product.
How to stay warm in the MT900 0°C Down sleeping bag
Dress lightly and wear a single layer of clothing, ideally in Merino wool.
Use a hat, gloves, socks and heat packs if necessary.
Opt for a sleeping bag liner to maximise warmth and avoid washing your sleeping bag too often.
Choose a mattress with good insulation (R-value > 4.8).
Tip: contract your muscles (70% of the energy consumed is converted into heat), avoiding any movements that could create a draught.
How to wash the MT900 0°C Down sleeping bag
Washing from time to time is recommended even if you use a sleeping bag liner.
Machine wash at 30°C with two or three tennis balls and our special down detergent (ref.: 8817232), and select a gentle spin cycle.
To tumble dry, use two or three tennis balls and run two to three cycles until completely dry.
How to repair the MT900 0°C Down sleeping bag
When trekking, accidents can happen quickly. We recommend using our self-adhesive repair patches (ref.: 8777140) to repair your damaged sleeping bag and prevent the insulation from escaping.
Otherwise, visit your local Decathlon store for a workshop repair.
