      Finally something that fits and is well made.

      Customer service is the best I’ve ever experienced. I got a medium and it was too tight for my Frenchie. So they sent me a large with a booster block FOR FREE before I even returned the old one. And they are paying for the shipping back.

      The bag is extremely high quality and fits my dog perfect. It’s very comfortable both my 40lb Frenchie and I. Wasted too much money buying cheaper ones previously.

      What a great product!

      This is just a great buy. My mini poodle is comfy and so happy in her new bag! I sized up to a large to allow for my broader shoulders. Very comfy for me and my dog.

      J’adore ce sac, il me permet d’aller en vélo avec pitou en pleine confiance qu’il ne sautera pas à l’extérieur du sac! Il est bien aéré et permet à mon chien de bien voir partout autour de nous.
      Il semble confortable et se laisse faire facilement pour embarquer à l’intérieur!
      Je recommande à tous ce sac! Belle conception, beau produit!

      Overall good but…

      So my boy is a 28lbs mini Aussie shepherd. Taken him out in it a couple times and he seems to enjoy it for the most part. Personally I think the storage pouch is almost useless and really wish the latest bag wasn’t twice the price cause I would have definitely gone for the upgrade just to have the storage at the base and not a separate piece.
      Construction seems good but time will tell.
