Side Effect + Water Bottle?
I've been using my SE to corral some things inside of my Synapse 25, and I'm beginning to realize I may be able to use it as a standalone purse for evenings/weekends, which would make switching to/from the Synapse so easy (of course, I'm also lusting after the black ballistic/iberian color combo to replace my steel dyneema/steel...). I don't carry all that much, so this would be fairly easy, but there's one major exception: my water bottle.
I'm a big water drinker and need to have a water bottle on me at all times. I'm actually about to buy a new water bottle, and I'm wondering if the right bottle could be rigged to attach to the SE in some way that wouldn't be a nuisance while walking (my main form of transportation). Or maybe someone knows a small bottle that could fit in the SE? One of those collapsible bladder-style ones perhaps? I'm looking for a 20 - 24 ounce-ish bottle, but wouldn't mind using a smaller (8 - 12 ounce?) bottle for when I'm out with the SE, since refilling is typically a possibility. Any thoughts?
