I love the WXP - I've been using it in my backpack, and I must say, it's great. Unlike some other products I've bought on the web, this one actually does what it's supposed to. It's very easy to fill and clean. I just throw it in my backpack, and then I'm off to a hike or rafting trip. The water and lemonade I use to fill it up have kept me cool and hydrated on some of my longer trips. And the fact that I can put ice in through the large opening at the top is a very big plus for me and the reason why I recommend the WXP so highly. Thanks!

Very good product. Easy to handle, safe, excellent quality. But on climbing a 5800m high mountain the water in the tube got frozen... What to do against that inconvenience?

Purchased the 3 L bladder several years ago after the one I had(another manufacturer) started to give a taste/smell to the water in it(think i didn't get it dry before storing it). This bladder dries very quickly via the wide openning. You couldn't lock off the drinking end on my last one, but this one is quick and easy to secure from accidentally leaking when I'm not actually drawing water. As Peter says, adding ice is easy. Great unit. HIGHLY RECOMMEND!

I bought it about 2 weeks ago. It has some plastic taste for the firs time. However, I think it is the best.

I bought this one, after using when I want to rinse and dry it, I cant. the bladder has been dried, but the tube not. After two days, I see many water drops in the Tube.

Hi Omid,
Make sure to download the Care and Use document (link is under the main product image). You'll find instructions to disassemble the valve and dry the tube.
Send us an email if you encounter any problems.

I am a mountain biker, using WXP for a month already. Very satisfied with this bladder, especially the water flow and ease of use of the helix valve. The only downside I have found is the Dirt shield. It is impossible to remove with one hand (which is important for MTB), and if left removed it constantly dangles around which is very annoying. I see that in your promotional videos involving MTB, the dirt shield is absent, so I believe you are aware of this issue. Nevertheless, product still deserves a solid 5 star rating!
