skimanwrote a review of Lezyne Flow Caddy with Organizer on June 11, 2016
Familiarity: I've used it once or twice and have initial impressions
I got this thinking it would replace my saddle bag but it holds less than my bag, which is not a very big bag. The organizer takes up a lot of space, wish I bought the one without it. It's basically a water bottle without the top. It's made of plastic, not aluminum, which is a good thing since aluminum would weigh more and could dent. Looks good on the bike though and it does provide the aero benefit for the rear wheel if you don't normally carry a water bottle on the seat tube side.
