I in need of a new 50l or so overnight walking bag... Something a bit lighter weight than my old one.

I'm tempted by a Big Agnes prospector 50l and there is a deal on them. 

Anyone used BA sacks? 

Other one was Exped Thunder 50, but don't see to be available in UK now. 

Big Agnes sacks who?

I don't know anything about Big Agnes stuff. Looking at weight and spec, an alternative might be Deuter's Aircontact Ultra 50. It is a fraction lighter than the BA one, and in other respects it's a mid-sized overnight pack that I really rate:

Would definitely say it's worth a look

The simond ones from decathlon aren't any heavier and are half the price. 

I've got the Makalu and its decent. 

I have a Lightwave Ultralhike 60 - also available in 50l version. Hardwearing, lightish, very comfy...a bit short on features that some other packs have (hipbelt pockets etc) but I've been using it for a decade and still in good shape.
