2 years


Machine wash at 30°C max. Add tennis balls to prevent the down from balling. - Rinse thoroughly. - Drying: the quality of our feathers and down has been rigorously checked; since these are natural materials, stains or odours can appear when damp. => The bag must be totally dry before storing. Tumble dry or leave to air dry flat, shaking and tapping it from time to time. - Dry cleaning not recommended
Storage Tips
Store your sleeping bag in its storage cover in a dry place because there is the risk of the down deteriorating if it is compressed for a long period of time in its compression sack

    Simond - Makalu Down bag

    This is a good quality product, it is a definite recommendation. It's a decent price for a decent down bag with good down insulation, it is light for my bicycle and trekking tours and covers all the needs of a good three season bag.
    The only drawback is the sizing (length), but I took into account the wrong sizing after looking at other comments for similar products made by simond, and thus got a larger size just in case, turned out it is just fine for my 170cm height. But this is something I would not consider a product drawback, just a mistake of the manufacturers measurements.
    Anyway, If you are looking for a good 3 season bag than this should be your choice if you want to pack relatively light, warm and cheap.

    Hält mehr als er verspricht

    Habe den Schlafsack bei -15° verwendet, mit einem Fleece und langer Unterhose gar kein Problem. Auch das Packmaß ist top und mit nichts in dieser Preiskategorie vergleichbar.
