Rated 4 out of 5 by from Great for commute and around town I have used this bag on daily commutes and buzzing around town. It is part of Topeak's lighter weight QuickTrack bag and rack combo. Small lock, wallet, cell phone, small pump, small tool kit, tube, lunch, and change in clothing all go in in this flexible bag. The slide off feature is fantastic. There is a little loop on the back to clip a tail light. While the zippers have not worn out I fear they will. I wish all bag makers would use the big toothed zippers. The bag's rack is light, the rubber pieces that go between the seat post and rack clamp are too fussy to make it something you'll take on and off quickly. So plan to put it on and leave it on. Over all it a great setup for a commuter.

Rated 5 out of 5 by from Great product I have used the larger model of this trunk system for many years...I am an all season rider. I love the versatility...morning rides to work require extra clothing that goes home in the evening in the panniers of this trunk. The only negatives I have found are that it is not waterproof (plan accordingly) and as it ages, the rack loosens up a little so the trunk rattles some over bumpy terrain or less than smooth pavement. (Solved by tying down the panniers with the supplied bungies). Overall, again, great product...I added the smaller one to my arsenal for a planned 130 mile ride.

Rated 4 out of 5 by from Good for commuting but would prefer bigger pannier I use this pack for commuting to work. It works great with my Topeak RX rack. It holds my lunch, wallet, phone (and shell pants/shirt on the warmer ride home) fine. However, The panniers are not large enough for putting 8.5 X 11 papers (and folders, and notepads) in. This means papers need to be folded in half, and no bringing rigid notebooks.

Rated 5 out of 5 by from Excellent product right size. After inexplicably losing my other (larger) bag, I picked this one up during a sale. I haven't been happier. As it turns out, the larger bag was too large for my needs. If I need to go grocery shopping, I just hang another bag on my rack. This bag has the same durability as my other bag, just smaller. There's room for a smartphone, my tools and an extra tube. Overall this bag is perfect for my current needs.

Rated 4 out of 5 by from Nice Little Bag I use this bag on my commuter bike and it works great for me. At full capacity I can fit a pair of pants, belt, socks, wallet, cell phone, and keys in the main compartment. With the panniers open I can fit a shirt and undershirt on one side, and a pair of shoes on the other. The shoes have to stick out the top of the unzipped pannier but I have never had any issues with them sliding around or worried about losing them to a pot hole. On cloudy days I can slide an umbrella under the elastic bands at the top. I use this bag with my Explorer MTX rack, which works great. Easy to slide on and off. If you are looking for a bag that can hold tons of gear, including tubes, tools, etc. for a long commute I would recommend one of Topeak's larger bags, but this works great for my relatively short commute (about 2.5 miles one way), and I keep a spare tube, etc in a seperate wedge bag. It's also great for pleasure rides around town, when I just need a few essentials.

Rated 4 out of 5 by from just right for around town trips! I use it manly around town/long day trips. I carry some tools/kits/maps/lock/and enough room for anything else I might buy at stops at store on way home. I will up grade to larger bags for serious trips of camping-longer travels needs.

Rated 5 out of 5 by from room for all necessities Bought this after seeing someone elses. It is great. Attached easily to bike. Holds all that we need for a ride and comes off easy to take with if we want to stop for lunch or something.

Rated 5 out of 5 by from Great bike storage I purchased this trunk storage for the STP, it worked great, carrying all my food, supplies, tool kit and clothes. The saddle bags are expandable and work great for large items. Love it!
