USWE’s No Funky Stuff™ - Hydration Bladders are disposable and help prevent bacteria growth in used bladders. Toss the bladder in the recycling bin before it gets funky and grab a fresh refill. The bladders are durable, inexpensive and BPA-free.
Bladders filled with water only can be reused a number of times, just clean with fresh water between uses.
Bladders filled with liquids other than water should be replaced to prevent bacterial growth.
Get fresh bladders and clean hydration for a very reasonable price.
Keep in mind that they do not come with the hose, bite vale or cap to accept a drink hose. they are not as tough as the shape shift or the bladder coming with packs. it's made cheaply for a reason. if you turtle the seams can and will probably burst. you should purchase https://www.rockymountainatvmc.com/riding-gear/uswe-disposable-hydration-system-p first and then buy the appropriate refill to replace.
The bladder that came with my pack was tough. These replacements are not. TIP - keep your bladder clean and free from growth by flushing it with warm water and them filling it with 6 parts water and 1 part cheap vodka. Be sure to get the solution in the hoses and bite valve also. I store my bladder filled with this solution. The vodka kills anything growing and prevents future growth. Just be sure to flush it out and refill before your next ride.
Yes, these bladders are inexpensive, but the durability/integrity is horrible. Honestly, I have a hard time believing that these were product tested or users that gave them rave reviews actually used them.
Not once was I able to use these more than one ride and a couple of times, they failed at the start of the ride. Loosing your water on a big day is a problem. Keep in mind, my application was moto. Though, I was careful and didn't crash with my hydration pack on or mistreat the hydration system. Saying that the packs are disposable and should be replaced after each ride is ridiculous since a ride could be one hour or ten hours.
I just replaced the bladder in my Leatt pack with a Hydrapak bladder. Though I haven't yet used it, it looks much better. It also looks like what comes in the new Leatt and Ogio packs, which is telling.
