A velcro loop or two on one side for a mini pump is a great idea. Because I always carry c02 cartridges, I totally didn't even think of it. I can also see where having a lighter color interior makes a lot of sense, as there have been times I've been digging around inside for something and had a difficult time because it's so dark.
We're currently making another batch of these so you may see a few minor adjustments surface in the near future. We're also thinking of making a second version that will be a little wider in addition to the original.
Thanks for the review/input!
