Have been using platypus bladders for years and have not run into any issues with any of them. Just got another one (1.8L) to go in a winter pack and so far it has performed as well as all the rest. No taste, no leaking, and lightweight...what more can you ask for?

I have many platys, still uning one that is 10 years old, and have never had a problem. This one sprung leaks the first time i filled it. The seal arround the edges did not bond correctly during maufaturing. The material is differnt then the others, softer and more flexible which would be nice if it didn't leak. I am going to go through platypus directly for an exchange so i can let them know how disapointed i am in their quality controll. I will post how well they respond.

i like this bladder for saving a bit of weight relative to my camelbak bladder, but i made the mistake of taking this bladder on a climb where we were required to melt/boil snow. because this bladder has a small cap opening, it was very difficult to fill out of the pot of boiled water. i should have either taken my camelbak, or ordered the wide-top opening model platy so i could full right out of the pot. my mistake, not the product's. we ended up using a trail mix package fashioned into a funnel to fill this bladder from the pot. apparently it works great with a step down water filter attachement, which is good when you have a non-frozen water source & filter.

Overall a very good bladder. Works well for my needs. The flow rate is pretty good. The trick is learning to bite the valve the right way before you take a sip and you won't feel your lungs cave in, pretty crucial when your huffing and puffing at high elevations. On a recent trip I left the bladder almost full outdoors, overnight, and in freezing temperatures (didn't know that was going to happen though). In the morning there was no damage or deformity to the bladder due to ice. Durable. If you have an MSR Hyperflow, this bladder works well with that filter. The flow spout of the filter fits like a glove on the mouth of the Platypus. There's a good lightweight combo for ya! Water tastes great coming out of this bladder (i.e. good water in, good water out) and won't alter the flavor of anything you put in it. I interchangeably use water, Crystal Light, Propel, or Gatorade, etc. for hydration with this bladder and it will not hold the flavor of the last thing you put in it. I have friends that use older Platypus bladders and they've owned theirs for several years. I expect these bladders to last just as long. Highly recommended.

I love the versatility of this piece of gear. If you don't have a water supply coming up soon then you can fill it up all the way. If you're crossing streams every 30 minutes then just fill it up to whatever level you like and let it take up less room in your pack. Very lightweight as well. I just wish it had a bigger opening to fill it up but that's a minor setback.

good bladder. i bought it because of its price and weight. also, my roommate in college had one and he really liked his. i am interested to see how the material holds up. i have heard that it does well, though.

my only complaint is that the only way to fill it is the small opening on the bottom where the hose attaches. i don't the mind the size of it, but its placement means that i have to completely remove it from my small camelback pack as opposed to simply lifting it 5 inches or so.

This is a great piece of equipment! It weighs about half a pound less that the CamelBak equivalent and it does not flavor the water. When empty, it rolls up and stows away small. I use mine with the MSR Sweetwater filter and the step-down cap fits it perfectly.

Works fabulous on the trail. Took a 3 day trip and this saved me. Think that the 2 Liter is a perfect size. Will tell others.
