I was happy to be able to select a pouch smaller then the previous one and this pouch is definitely an improvement with the clip on features and "twist to open" mouth piece.
First use impression is great. Only time will confirm.

. Merece la pena,totalmente RECOMENDABLE
I was able to use the Widepac bladder in 5 major hikes, 4 backpacking trips and lately, beach camping. After taking off the hose to refill the bladder, i observed a slow leak coming from the female side of the bladder from some of the leftover water inside, but i still refilled it with water and re attached the hose with no leaking after the hose attachment. (i guess the male connector sealed it again).
Now the pros: the bladder itself is bomb proof! no amount of pressure from a loaded backpack would make the bladder weak and leak.
The big opening is easy to refill and re seal and clean.
And last, no funky taste from the bladder after refilling it multiple times on multi day hikes.
Overall, i would still buy a source hydration bladder and I'm thinking of getting the WXP model so i could use my water filter directly on the bladder if needed.
I work in the Western Australian desert most of the time, doing 12 hour shifts at gas plants or mines for 14 days straight, give or take. On other bladders the bite valve has been the first to go, or the seal around screw top. On the Source it sprung a leak around the plastic seal at the bottom of the bag, looks like a V the encircles the exit for the water to go into the tube.
84 days is pretty good considering the arid environment, constant use (too tired to empty it once clocked off so it stays full for the 14 days and nights) and it gets treated a little intensely on site.
The bag gets packed with equipment and supplies, it gets chucked in the back of cars, crib huts etc. Also crushed in confined spaces when I am squeezing through with it on me.
Will buy another as the water tasted nicer at all times.
I have had my Source for 3 years now and it really is just like new. 5stars to Source for outstripping the competition and producing a truely useable product at a very reasonable price.
Ive used the source widepak with my salomon, I have to say it was a great innovation for the drinking tube to be removable without leaks.
However the joining area of the mechanism and the tube came loose just after 1 month of use. The fitting because unusable and I could not fit the mechanism back into the housing. Perhaps a change in design to make the detaching mechanism a permanent part of the bladder would be good for the next version.
The Source one had no such problems!
Never leaked - even under a full, oversized backpack.
Downsides- Closing the bladder's top can get tricky if you really want fill it up all the way, and it isn't comfertable to hold outside the backpack (but not having a handle saves space... so...)
All in all - the best bladder i've used. No leaks, No smells, the tube comes out, and it can stand a LOT of pressure.
Way to go!
DAY 2 - Around Lake Toba
Richard is now out around lake Toba. he's meeting the locals and enjoying the scenery.
When he finally sits down to explain what he likes so much about the Source Widepac, the Volcano erupts behind him!
But an erupting volcano is not going to stop Richard from running - in it's direction!

" For the experienced outdoors-person and beginner alike... "
" The product worked well and held up to abuses..."
" Our tester left water in the Widepac for eight weeks without cleaning and reported no stinky taste or smell."
" More to love: The top opens wide like a paper bag for rapid filling. "
" You owe it to yourself to use one of Source’s reservoirs. They truly are the best, cleanest-tasting reservoirs we’ve ever used. "
