Nice for the bike!
- Familiarity: I've put it through the wringer
The first thing to call out: this is a small hip pack. Topo Designs' site claims it's 2.5L, while Backcountry claims 1L. I used a plastic bag stuffed inside and filled it with water and got around ~1.3L liters.
It's not a ton of space, but I've found it to be quite nice as a replacement for jersey pockets when I want to ride a bike in a normal shirt.
The main compartment has room for my mini pump, wallet, phone, and a couple of granola bars. A slip pocket inside the main is a good place to stash something you won't access often. I keep my wallet here so I'm less likely to lose it while getting other things.
The front pocket is just a slip pocket with no added depth, so it can't take too much. It has a key clip, so I keep my house keys, a chapstick, and a spork (for emergencies!) in there. It will fit my iPhone 11 Pro with a small case on it, but the diagonal zipper makes it clumsy to get in and out.
Further perks include a clip for attaching a bike light, and a set of straps on the bottom that could hold a vest or light rain shell.
The pack is very comfortable given the wings, 1.5" strap and its small size. The padded structure is nice - I can't feel my mini pump against my back.
The waist belt is easy to adjust, both tighten or loosen. It can loosen a bit over time while wearing, but not enough to be a bother and is easily tightened back up.
Generally I'm quite happy with it for bike usage. It'll hold what I would normally put in jersey pockets with the added benefit of keeping sweat away from the contents.
- There are no strap keepers for the waist belt, so the excess flops around (there's not too much though)
- The bottom compressions traps are a little short; I can fit a ultralight rain shell, but I would struggle to hold a fleece or anything larger.
- The diagonal zipper on the front pocket can make access awkward
Another interesting use: It'll fit a Nintendo Switch! (a bit snug longways)
