Hmm.. bulky. I reckon stuffing the kit down the neck of my jersey is probably better. Since it's a 600 it's no great shakes stopping, folding it up and storing it more neatly in a spare pocket I guess. I could carry less food and buy more at each control. I finished the 400 with spare drink powder, spare bars and spare gels. I could just expand the saddle pack a little and that would leave a pocket free for arm/leg warmers.
I have an Alpkit Airlok Dual 20l thingummy that you are welcome to try if you want. It's light but I could find little use for it. You are welcome to borrow it if you think it may be of any use and are able to collect it from EC2.
