I agree, they look nice!!
Would agree with LLB re jacket size - i'm a size 6 usually so a bit bigger than LLB, I have the XS which I can get a couple of layers under but they are not thick ones plus, despite having a v narrow back I have wide shoulders for my frame (call me strange!!) so this size fits perfectly but couldn't get a thick layer under it.
I've got OMM ultra 15 which does me fine for pretty much everything - has a bungy that goes across the back that lets me pull it in when I have hardly anything in it except for my bladder.
LLB - think you were asking about shoulder holsters for bottles on other page (can't remember what's being posted where so apologies for getting REALLY confused!). I don't know if you can buy general fittings that fit on any bag, I think OMM and poss Raidlight have some kind of system for their bags. Was starting to think about this myself as although I use a bladder, it's a complete pain to refil when you go through checkpoints, especially if you don't really need to properly stop. Would much rather NOT have to open up/unpack my bag. Otherwise I guess it's time to get creative with elastic and make your own holsters!! I'd quite like to get the pack that snaps on the front of my OMM sac so I can store more raisins etc in there plus a map to save me trying to run with it in my hand all the time.
This thread or the other, some talk of food on the go - I eat honey sandwiches, tried peanut butter but find it really dry unless I've got jam in there too. I also love peanuts/raisins/chocolate drop mixes with some coffee beans thrown in for a bit of bitterness and a kick amongst the sweetness, bit crunchy but seemed to work ont he Northumberland one.
