I need a lightweight 'runnable' sack.
Anyone got any experience of the Terra Nova Laser 35 Lt sack?
Found one going cheap (Field and Trek), but it doesn't seem to have a place for a bladder as its got a vertical zip closure.
Alternatives are an OMM 32 or the Inov-8 30 (but that means buying an Inov-8 bladder). Choices, choices
