OspreyEscapist Unisex Biking Frame Bag, Black, Medium

Although I bought the wrong size for my bike and returned it for the correct one, I have been totally satisfied with the quality construction and materials used in this frame bag. It is one of the best bags I have purchased for my bikes. The price is a little higher but well worth it.

I ordered the Osprey Escapist Unisex Biking Frame Bag, Black, "Small".I ordered this for my gravel bike top tube and I believe, based on the strap arrangement, that it is meant solely as a top tube bag (i.e., not downtube). If your top tube is long enough, you could mount it to the front of the top tube or to the back of the top tube.I ordered the small and it is 15" long, 2" wide and 5" tall at its maximum. It comes with seven straps four of which are already attached and one is flat inside the bottom of the large compartment of the bag. There is one loop for a strap on the front, one loop for a strap on the short slanted section, one loop for a strap on the back and five loops across top for straps. There are no mounting loops along the bottom. You can attach two or three straps together to make one longer strap if you need a long length to reach a particular tube. The large compartment has two zippers that you can use to open the compartment from either end. The large compartment is just one large compartment with no divider. The smaller compartment has one zipper And has a divider. The smaller compartment is for things like credit cards and cash and maybe your cell phone. I don't think it could hold anything larger than perhaps one half inch thickness.Both zippers have protective covers that you slide the zipper into which helps with the water infiltration resistance. I have not tested the bag for waterproofness, yet, but I'm sure it will do fine. All of the seams look well done.There are three tags inside the large compartment and one of them says this was made in Vietnam. A second tag shows manufacturing materials and handling instruction such as cleaning.Overall, 5 stars from me for now.

I originally got this for myself for my road bike but turned out my bike is just slightly too small for this size bag. Since I just love the osprey brand so much, I decided to give this bag to my nephew instead who is slightly bigger than me and his bike frame is also slightly bigger than mine. This bag fit perfectly for his and he has complimented how well build the bag is and can fit a good deal of stuff inside the bag. I will prob try to get the same bag just smaller for my own frame, but overall this is a fantastic frame bag for your bike. Just make sure you get the correct sizing for your frame

Impressions:- The large size is definitely best for size 58CM and above frames.- While this fits my frame perfectly, I do have to exercise a bit of care removing my front water bottle, and returning it to its holder.- There's a massive amount of storage in this bag.- Build quality is exceptional.- I wouldn't characterize this as waterproof, but I've ridden through more than one rain storm, and all my contents remained dry.Highly recommended4 stars

I got this bag to hang on my scooter - which isn’t ideal - so I’ll most likely be moving it to my bike. The bag itself is quite good; it’s made from thick TPU that’s RF welded together and the overall build quality is very good as I’d expect from Osprey. It’s also extremely light, much lighter than if it were made from nylon like traditional bags. The zippers are waterproof as well, although a bit stiff until they’re broken in, but do work well thanks to the attached cord pulls. I like how the bag has dual compartments, with one being fairly slim which makes for a good place to put my wallet, keys and phone if it’s not attached to the handlebar mount. The other compartment is large enough to fit an air pump and tool set along with some miscellaneous kit, like a light and snacks. The system for attaching the bag is also excellent; there’s tie downs on 3 sides of the bag and thick velcro loops are included, but the great thing is that they’re removable unlike pretty much every other frame bag I’ve used. After it’s mounted, any remaining straps that aren’t being used can be removed and there’s no unsightly loops flapping around in the wind. I like the bag quite a bit and can recommend it if you just need a place to store some repair essentials and small pocket items.

This is an excellent addition to a bike that needs to carry a lot of gear, but only if you come up with an alternative water storage solution first. This bag is well built, offers water-resistant zippers, among other things, and a lot of storage space, but in my case, it comes at the cost of being unable to mount water bottles on the frame. If I were bike packing and carrying all of my water in a backpack, this would be an excellent way to store all of my spare parts and tools, but for everyday use, it’s more of a burden than anything, drastically limiting its utility.

This is an excellent storage container for my bike and absolutely a great quality. However, the measurements they give you to determine the sizing are very rigid and precise and I was hoping to fudge them a little bit and fit the larger version inside my bike even though the measurement of my bike was just a shade too small. I was able to get it to fit and I'd probably do it again, but I have to admit the top part of this bag is a rigid plastic and I had to bend it to get it to fit. With everything being such a beautiful construction it is a shame to see it with the bend because of the way I wedged it in there. Yet, it doesn't appear to have affected the usability or waterproofing so I am content.
