    We love our MookieMerino sleeping bag! The quality is great, it’s cosy, dries really fast and adapts great to any temperature. Pity my older daughter was aready two when we bought it and grew out of it soon but we just got a new baby and she’ll definitely start using it soon and can use it for a long time 🙂 Keep up the great work!

    We are very happy with our MookieMerino sleep bag. It feels incredibly soft. I wish they made one for adults! Our baby has slept really well in it and always seems to be at the right temperature. I highly recommend it.

    Great product! It is so good to know the baby is not going to overheat or get cold….It feels beautiful and my granddaughter looks so comfortable in her cot in her sleeping bag. It is the best one I have seen (and I have many grandchildren).

    Vraiment contente de cette turbulette de haute qualité ! Elle est très douce donc la température du corps de bébé reste toujours stable et idéale pour lui ! Sa possibilité d’ajuster la taille en fonction de l’âge et son espace pour faire passer la ceinture de sécurité sont vraiment bien pensé et lui permet de toujours dormir dans son sleep bag préféré même à l’extérieur de la maison.
    C’est une turbulette que je recommande fortement ! Bravo à la fondatrice !!!

    Doux, bien fait et bien pensé. Et rare sont les vêtements de bébé qui durent 2 ans! Un produit de qualité et très original à offrir en cadeau à un shower de bébé! 😉
