Google is not solving my problems!
I'm trying to cut down pack size (always am) for my cycling this summer - if you can think you can pack light try packing with this kind of setup including camping gear, food and cooking:

I've now got refillable pens and so currently have a Clikstar pen for Lantus and novopen 5 for novorapid. I aim to take 1 of each pen and 2 spare vials of each. Will this fit in the duo wallet?. I'm pretty sure that I could fit 1 pen + 2 vials in the single one, so would it be less space taking that if the duo doesn't fit it all?
