Baen Sendi 2 Pack Hydration Bladder 2 Liter/70 oz - Water Bladder Pack of 2(1 Piece Blue+1 Piece ArmyGreen) - BPA Free Hydration Pack Replacement

I'll start with the pro and cons.... Pros: Perfect fit for my Osprey backpack and a generic hydration pack 100% leak-proof during my entire 5-day trip to 3 Utah national parks Wide opening makes filling and cleaning quick and easy Comfortable bite valve with smooth water flow and no drips Protective cap keeps mouthpiece clean on dusty trails Durable, high-quality materials that feel as good as premium brands Great value: quality matches more expensive hydration bladders Cons: 2L size is ideal for short to medium hikes but may be too small for long, strenuous hikes (I ran out of water by the summit of Angels Landing in Zion) but this was poor planning on my part. My Experience: I bought the Baen Sendi Hydration Bladder 2L to stay hydrated while hiking in Zion, Bryce Canyon, and Arches National Parks. It fit both my Osprey backpack and a generic hydration pack perfectly, with zero leaks the entire trip. The large opening made refills at trailheads quick and easy, and the protective mouthpiece cap was a thoughtful touch, especially in dusty desert conditions. For short day hikes, trail running, or cycling, this water reservoir is perfect. If you’re planning an all-day trek, I’d recommend going for a 3L version. Overall, this is a reliable, durable, and easy-to-use hydration bladder at a price that’s hard to beat. I’ll definitely buy another for future adventures.

Was gonna give this 4 stars because it showed up late (what’s the point of Prime if not the delivery??) but that’s an Amazon problem, not a Frienda problem. The pens themselves are phenomenal. I’m a big pen person and usually only use my stainless steel Zebra, but these surprised me. They feel good in your hand, don’t feel as flimsy as they look, and have a cool, sleek vibe. Writes like a regular fine point pen and the ink dries basically instantly, which I love. Since it’s a liquid gel it can bleed small writing together a bit, but it’s not a dealbreaker. I’d totally buy these again and will probably grab the colored set for drawing 👀

The blue one started leaking from the bottom, where the drinking tube connects. Made for a completely wet pack and gear, as well as not having water for a 10 mile hike. Later on, we found a leak around the fill hole area as well. The green one has not had any issues...so far....

Well worth the money. Works as expected, no leaks and easy to install.

Great replacement for any hydration pack

Needed a replacement bladder for my camelback and this was pretty much the same thing for half the price.

Great system, easy set up and works as reported.

I'll keep this short and to the point: The bite valve sucks and lets air in while you are drinking - like a cracked soda straw. Very annoying on the trail. Can't seem to fix it, it just does it every time you open the valve to get a drink. The other little annoyance I have is the keeper that retains the lid when open... The lid keeps coming undone from the little keeper/retainer, and then drops. I wish it held better. The plastic tab that does the actual retaining sense to be weak and I suspect it will fail completely soon. The bladder itself is great. No leaks, the lid seals well and the connection between the bladder and hose works as it should. I do wish I would have got the 3L. Maybe I got a bad one, but I suck as much air in as I do water when drinking from this, which is no good.
