Must have for hikes. Efficient and durable.
4 out of 5 stars
Must have for hikes. Efficient and durable.
No leaks. We hiked for 3 hours and there was enough water. We used them for our 3 daughters and they only fit the water sack and their phones inside. But it was lightweight; they never complained about it being bothersome. Each of our girls were different ages and heights, but the bag adjusted accordingly. It was such a convenient hiking gear, being able to drink water efficiently, while having both hands free.My only thing was I wished it had just a little bit of more wiggle room, but it wasn’t a huge issue.

    Bought for an 8 year old runner. It’s slightly large for a child but he manages. We fill
    It with water and ice and it’s still quite cool after his long runs close to 2 hours. Most important for me is the high visibility out on the rural roads. It’s a bright color for sure.

    Picked this brand Camelback since it is reputable for not leaking. Got smaller camelback for riding on e-bikes. So far they are a good. After a full season of using them, this will be the real test. No plastic taste drinking through straw, weight is not too heavy when filled with water.

    I was so excited to get this on Prime Deals, I already have an USWE hydration pack but wanted to get something for my partner for when we ride bikes. Unfortunately the first time we went to use it I filled it up, left it on the counter to go change and came back to a flood in my kitchen. It has leaked everywhere. No matter how many times I tried to get it sealed it never would. So disappointed!

    Gutes Produkt. Nur die Reißverschlusstasche ist sehr klein. Mein Handy passt nicht rein. Wenn die Blase voll ist, passt gerade noch ein Schlüssel rein. Für mein Handy habe ich mir eine Bauchtasche besorgt. Ich nutze den Rucksack auch bei kleinen Strecken ohne Blase, aber dann kann man in das Fach wo die Blase reingehört, trotzdem kein Handy reintun, weil sich dann die Lasche nicht festmachen lässt, die liegt dann nur lose oben auf (wenn die Blase drin ist, wird die Lasche vom Blasendeckel gehalten). Vielleicht nähe ich mir da einen Klettverschluss dran. Ansonsten sehr schönes Produkt, die Signalfarbe ist auch gut.
