    Makalu sleeping bag review

    I used it in a trek in sikkim. Its a very warm sleeping bag but the only problem with it is that while sleeping the down benathe you moves out to other places in the bag and after some time your back is cold, it may be because there are no seams to hold the down to its place benathe your back. I want a solution to the problem. Please suggest.

    Unglaubliche Preis-Leistungs-Verhältnis!

    Schön beim sehr kalte Termperaturen bis min. -15°C getestet am 1.May auf 4000m höhe im Zelt auf dem Schnee. Kein moment kalt gehabt und normal richtig schnell zu kalt für mich. Sehr gute Leistung und für dem Preis unglaublich!!!
