Ultraspire 2.0 Bladder for Hydration Backpacks - BPA & PVC Free - Leakproof Water Reservoir

Perfect. Fit and durability

I have used a hydrapak for years but after five plus years it finally leaked. So I bought this as the replacement appearing to be the exact same product as I previously purchased. But it’s not. The advertising is misleading. The loop attachment is changed from previous even though the packaging still shows the old product and design. It is very hard to attach to a pack. Or maybe it’s not but there are zero instructions on how to use it. Will probably try to reach out the company to figure out how to use it and may have to return it.

Qualität und PreisGewicht und LeistungAlles gut

Exactly what I wanted it to be. I was worried it would be big enough to slosh around when I ran but there was none of that. However, even having read that it was so hard to find out where to open it, I had a hard time opening it. The opening really is AS FAR TO THE TOP AS YOU CAN GET. if you aren't pulling both sides apart at the absolute highest point, you aren't in the right place. Nope, higher...

It's great. Easy to use, dishwasher safe, good one, not cheap though.

Works great. I need to replace my old bladder that was over 5 years old.
