Question: What size is the drinking tube? Is it 1/4 inch? I was thinking of getting some Sawyer inline adapters to use with it and they fit 1/4 inch tubes.
Document: The wide open end of the bladder makes it very easy to clean and dry it after use. This is much better than other brands with a screw on cap. Like the others though, drying the tube is still a problem. A good design improvement would be easily removable fittings to let air through it to speed drying. The quick connect on the bladder end is easy to use. The dust cap on the drinking end keeps it clean.
These were great! My wife and I bought them for the San Francisco World Naked Bike Ride. They held plenty of ice water, no aftertaste, and fit fine in out day packs. Love them. They'll get some more use with some hikes we have planned.
If you're intending to use a Source &#34;Universal Tap Adapter&#34; for quick refills of the hydration pack, be advised that it doesn't fit this model because the mouthpiece doesn't contain a quick connect. When Source calls the adapter &#34;universal,&#34; it suggests that it fits all their units, but that is not true of this unit.. I had to return it so I could buy another that was compatible with the adapter.
I first heard of Source Hydration when I was in the Marine Corps. This is the brand that they issue us. I found it to be a little better than the Camelbak that I purchased off base. I continued to use the Source blatter all the time until I turned it into CIF when I EAS'ing (getting out). I bought this blatter because it fits perfectly into my Northface Backpack. There are plently of videos put out by Source on youtube if one needs a better look at their products.
This is a simple to use, durable hydration pouch. The slide off top is very simple to use. Filling the pouch is easy. The snap on/off hose is very nice for cleaning. I'm still trying to figure out the best way to incorporate this with the Sawyer filter, but would highly recommend it for anyone who needs easy access water.
We bought two of these to fill each day on a 4 day trek and they were great. Fairly easy to fill and great that they have the nozzle cover to stop the nasties crawling all over it.The one thing we find slightly difficult is how to dry them out once we are done using them (otherwise they would get 5 stars).All in all a great hydration pack and very easy to use!
Fits nicely in my pack holds plenty of water but a little difficult to get water out while drinking. I would like better water flow.
Used in my bug out bags, these items fit perfectly in the standard backpack hydration slot. Simple assembly, and durable connections. Easily cleaned, all per advertized. I can think of no improvements or 'if it only...'
Perfect size bladder. Holds more water than stated but not too heavy to carry all day long and is ample for a long day of hiking.
So far so good. Easy to clean and fill. Perfect size for a small backpack. Good quality material. The smell disappeared after a couple of weeks.
