      Description

      This sleeping bag, made from 90% down and 10% recycled feathers, allows you to sleep comfortably at temperatures above or at 5°C.

      What are the features of the MT900 5°C Down sleeping bag?

      Anatomical hood with drawstring. YKK double-slider zip, equipped with an anti-snag system, allowing optimal ventilation. A baffle along the zip prevents heat loss. Inner zipped pocket. Two loops at the bottom of the bag allow it to be hung up to air or dry. Comes with a storage bag in perforated fabric.4 cm 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.

      And what is the limit temperature rating?

      The limit temperature rating is the minimum temperature at which an average person (male, 25 years old, 70 kg, 1.73 m) is able to sleep in a curled up position without feeling significantly cold. For your information, the extreme temperature is the minimum temperature at which a person can survive (risk of hypothermia) for six hours. This is a safety measure, not a comfort measure.

      Which mattress should I use this sleeping bag with?

      The protocol for measuring the thermal performance of a sleeping bag is to use a mattress with a thermal resistance corresponding to an R-value of 4.8. If you use a less insulating mattress, the thermal performance of your sleeping bag will be reduced. We therefore recommend that you use an insulating mattress for better thermal comfort.

      Weight and dimensions of the MT900 5°C Down sleeping bag (may vary by +/- 5% due to production tolerances).

      Size S (users ≤ 1.59 m): 670 g (including 280 g of down/feathers)Folded dimensions: W 27 cm Ø 15 cmVolume 6.7 L Size M (users between 1.60 m and 1.69 m): 750 g (including 322 g of down/feathers)Folded dimensions: W 27 cm Ø 16 cmVolume 7,6 L Size L (users between 1.70 m and 1.84 m): 830 g (including 370 g of down/feathers)Folded dimensions: W 27 cm Ø 17 cmVolume 8,5 L Size XL (users between 1.85 m and 2 m): 930 g (including 420 g of down/feathers)Folded dimensions: W 31 cm Ø 18 cmVolume 9,5 L

      How resistant is the fabric on the MT900 5°C Down sleeping bag?

      The outer fabric is 100% polyamide 20g/m2 in 10 denier and Ripstop 30 denier. This fabric can withstand 80,000 abrasion cycles. Resistance is calculated using the Martindale test (Standard 12 947-2). This test involves rubbing the material of the bag 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?

      This product does not contain any intentionally-added PFAS treatments.

      How to stay warm in the MT900 5°C Down sleeping bag

      Simply dress in light clothing (one layer, ideally Merino wool, is sufficient). Warm up your extremities with a hat, gloves, socks and hand/foot warmers if necessary. Use a sleeping bag liner to optimise warmth and avoid washing your sleeping bag too often. Choose a mattress with good insulation (R-value > 3). And here's a little tip: contract your muscles (70% of the energy consumed is converted into heat) but don't make any movements that cause cold!

      How to wash the MT900 5°C Down sleeping bag

      Even if you regularly use a bag liner, you will need to wash your down bag from time to time. You will find all the information you need on the Decathlon Sports Advice website. In summary: 1/ Machine wash at 30°C with two or three tennis balls. Gentle spin cycle. Use a special down detergent (ref: 8817232) 2/ Tumble dry with 2 or 3 tennis balls, and repeat 2 or 3 times until completely dry.

      How to repair the MT900 5°C Down sleeping bag

      When trekking, you may well get a tear in your sleeping bag! The good news is that it can be repaired to prevent the tear from getting bigger or the synthetic fibres from escaping. We recommend using self-adhesive repair patches (ref: 8777140). If you don't feel comfortable doing this yourself, we offer a repair service in our Decathlon stores and one of our specialists can apply a heat-bonded patch for you.
