Great small reservoir
Review by Peter E. on 4 Apr 2025 review stating Great small reservoir
Great small reservoir, nice small size, perfect for smaller trips or for my kids to carry. Not as easy to clean and dry as the ones with the top opening zip, but still fine. Very durable and happy with it so far.

Decent for the size
Review by Sara B. on 26 Jun 2024 review stating Decent for the size
Got this for my toddler for his hiking backpack. Overall like it but don’t love that you refill it in the same hole that the hose connects to. Prefer the design of the bigger pouches with the top that opens. But good 1 L pouch and works for us!

Great size
Review by Connor H. on 2 May 2023 review stating Great size
This is the second one I've purchased for the second kid. Great for bike rides and pair it with the magnetic drink tube clip for easy storage and retrieval.

Perfect little hydration pack
Review by Ashli H. on 3 Oct 2022 review stating Perfect little hydration pack
This is a great little hydration pack that doesn’t take up too much space in my backpack. Does what it’s supposed to. Also compatible with filtration kit.

Just what I was looking for
Review by Matthew C. on 13 Jul 2022 review stating Just what I was looking for
Perfect little hydration reservoir for small bags and short adventures. I have a 3L which gets heavy and I find I never drink it all. The 1L works great.

Quality seems good
Review by Tilman H. on 5 Jun 2022 review stating Quality seems good
I bought the Hose Reservoir with the intention of using it as a gravity filtration system. I liked that it has a loop at the opposite end of the opening. The loop seems well made and more than strong enough to hold the full bag and filter.
I was also very happy to see that unlike on my other platypus bag it fits my Sawyer filter without leaki...Read MoreRead more about I bought the Hose Reservoir with the

Small and lightweight
Review by Jeremy T. on 18 Dec 2021 review stating Small and lightweight
I bought this for my son to use on summer mtn bike rides. We haven’t actually tested it in real life use but have filled it up to see how it works. I’m happy with it overall. This model is priced right for a entry level model but it lacks the wide opening on the bag. I plan to use it only for water as cleaning sports drink out of it will be more d...Read MoreRead more about I bought this for my son to use on

Hoser Platypus 1L Reservoir
Review by Carol G. on 14 Aug 2021 review stating Hoser Platypus 1L Reservoir
I bought this to replace the Reservoir in my 20 year old Camelback. The 1L size fits perfectly. I haven’t used it yet so unsure how it will perform but my daughter has a 2L Platypus she has been using for a few years and is very pleased. Based on her recommendations I purchased one too.
