Thanks all… Very helpful. I appreciate it. I feared for this thread at the start :-)
CraigW – thanks for that. Yes bottom rib measurement I am 34 which puts in small or medium but I have a 38 chest so not quite sure where that leaves me. I think small would be the best place to start …
ML – everything you’ve said echoes my thoughts. The s lab 12 is exactly what I was going to go for. I’m just concerned that the 12l is overkill whilst the 5l looks like it might not be enough. It looks tiny on YouTube reviews.
I have a 60 mile trail run I’m training for. There are checkpoints with food, drop bags etc so I only have to carry the mandatory kit plus my ‘essentials’ – jacket, spare top, hat, gloves, map, small amount of food , the usual stuff really. I’m just not sure the 5l would be enough. I don’t want to be taking layers off and not having space for them…
Does the 12l feel big? There is no between which is why I’m looking at the UD 3.0 as that’s 8.5l which seems a Good compromise.
Dark plunger – I have, thanks..it looks a bargain BUT I want the bottles on the front to free up rear space and make refilling easy. I don’t want to put the bladder in the back – need that space for gear.
