Did the WHW race using this 20 quid sac and found it extemley comfortable with no noticeable movement and no chaffing even on the shoulders when wearing just a vest pretty good over 95 miles i reckon.

IMHO it is an extremely good buy.

It may be of interest to some, but i recently purchased a mountain life aqua 6 hydration system from the mountain warehouse, the cost was a lowly £19-99.

It comes with a 1.5 litre Bladder, which i find ample,as it it never that difficult to find water to replenish it (but then i am not adverse to taking water from flowing Becks streams, burns and springs), it also has ample space for a days provisions and lightweight waterproofs etc.

I have had a couple of 20mile plus runs with it and find it to be more comfortable than items i have paid over twice the price for.

Of course i have not had it long enough to vouch for it`s longevity but there is nothing obvious in its build quality that would suggest it won`t last.
