Les poches
Legere Pas assez de poches

A l'intention des concepteurs, je souhaite passer un coup de gueule contre la disparition des poches pour des raisons incompréhensibles (on aurait moins de choses à ranger dans ses poches en 2016 qu'en 2012 ? ) Sur l'ancien modèle de doudoune légère Simond puis Quechua il y avait les deux poches latérales, une poche de poitrine extérieure, une poche de poitrine intérieure et des compartiments intérieurs en filet des 2 côtés où on pouvait mettre rapidement son bonnet des gants et cetera. Je note que cette tendance stupide est l'apanage de tous les fabricants. C'est bien dommage que vous y cédiez aussi.

Brand response :

Je vous remercie d'avoir pris le temps de rédiger votre avis sur notre site internet, je suis désolée que vous ayez eu ce constat négatif sur nos vestes duvet light SIMOND. 
Effectivement nous avons conçu, en 2013, une veste duvet light en remplacement de notre veste chaude en ouate (présente en magasin depuis 2009). Cette dernière était lourde et volumineuse, et donc moins adaptée à notre usage qui est l'alpinisme où la légèreté est primordiale.
Sur notre veste duvet light SIMOND, nous avons 2 poches repose-mains qui sont placées au dessus du harnais permettant un accès plus simple en montagne, la doublure des poches peut être utilisée comme poche de rangement : des gants, du bonnet... C'est dans ce sens que ce produit à été conçu, être léger et chaud. Vous avez raison, la poche poitrine et la petite poche intérieure ont été supprimées du modèle duvet light SIMOND, par contre nous avons toujours ces poches intérieur et extérieur sur nos vestes protectives et imperméables, laissant un accès plus facile lors de la pratique.

    Bought this a week ago and it's been consistently leaking feathers ever since. I don't know if it's just my jacket or if they are always like that but my previous (non-decathlon down) certainly didn't leak anywhere near as much!

    It's a shame really because otherwise it's pretty good, certainly for the price.

    Brand response :

    Thanks for your feedback on the Simond light down jacket. It's a shame to hear about the issues you are having with the down. I have recently purchased the same jacket and so far its okay so I'm hopeful it's a one off. Please drop into your local store or get in touch with our Customer Loyalty Team where we can exchange the jacket for you.

    Gute Jacke die erste Woche, aber danach...

    Ich habe mir die Jacke gekauft, weil sie einen guten Eindruck macht und die Qualität der Daunen sehr hoch ist. Die ist Leicht, klein Packbar und Warm. Aaaaaaaber: die Jacke hat viele Daunen verloren (normal für die ersten Wochen, dachte ich). Nach etwa 3 Monate verliert sie Daunen wie verrückt! Die Autositze oder Pullis bleiben voller Daunen. Ausserdem sind viele Nähten rausgesprungen.

    Ich würde diese Jacke auf keinem Fall weiter empfehlen, in dieser Preiskategorie sollte man höhere Qualität anbieten!
