We’ve been out on the local trails lately, and I’m proud to report I’ve got several mountain rides to my credit now.
Hydration packs can be a real problem when you’ve had a back injury somewhere in your history, and my friend, Connie, has an old break in one of her vertebrae that can get painful on long rides or whenever she tries to put weight on her back while riding. So, she was cautiously optimistic about a waist-style pack she got from Polarpak recently. After a couple of great rides using the pack, Connie tells me:
I’m a Polarpak FlowJo convert!
The FlowJo didn’t shift around too much while we were popping over roots and rocks and the weight of the pack rested comfortably on my hips and away from my lower back. Ahh!
The 24 ounce reservoir has a pressurization system that lets you pump air into it, so you’ve got a positive flow of water/drink when you bit down on the valve, but you can use it without inflating, too. All the hose connections are quick release and stay sealed when they are disconnected — just a twist and they are off, without any leaking.
There’s a baffle system inside the reservoir that keeps the sloshing to a minimum, but it also makes it a challenge when you’re trying to dry it out with a towel.
Some antimicrobial treatments on plastic reservoirs keep flavoring your water for a long time, but I didn’t taste anything but my drink after an initial rinse of the reservoir.
My favorite feature, though, is the big pocket in the pack itself. I was able to cram in everything I needed for the ride: gels, a cell phone, ID, energy bars, and even my tools and flat kit. It’s perfect for riding or running.
There you have it. Connie is a new mountain bike rider and her only hydration so far has been from caged water bottles, which just love to pop out and roll around when the going gets really rough. The FlowJo means she stays hydrated and the rest of us can stop rolling over her water bottles on the ride!

in when I can. That means some chilly, early morning rides. And when I get back home, the last thing I want to do is drink a big glass of recovery drink - heck, it’s hard enough to make myself drink on the bike when it’s really cold!
