I feel badly about this 2 star review but, buyer beware. First off, the product is excellent quality in terms of construction, quality and reputation. The problem is, the sizing is not reliable. I've ordered 3 PETZL products, all of which are the correct measurements and they were all way too small. For example, my kid is 50 inches and 55 lbs. The items I ordered stated it could handle above that, max to 40 kg/80 LBs, and yet they barely fit. At it's largest size expansion my small framed child was tight in it. I would have gotten one season out of it, nothing more. I know this is a European product so maybe the kids are smaller frame, but something is not right. Keep that in mind before you buy.J'ai reçu un produit pour enfant qui me sert à rien, malgré la description qui precise bien : "PETZL Bretelles Body Bleu Pectoral Adulte Unisexe, One Size"Un retour serait demandé...
