I looked far and wide for the best seat bag and I think this Avenir is the best for the price. Three sizes to choose from; I went with the medium not knowing exactly how big it would be. The depth measures about 6.25 inches and at the opening/flap the bag is about 3.5 x 3.5 inches. If you unzip to expand the bag you'll gain another 0.5 to 1 inch in height. I didn't find any pictures of the inside, but there's a mesh elastic pouch on the inside of the flap along with a clip to attach a key ring or the like.

The bag feels VERY sturdy and I have no concern that it'd fall off my bike. Another note is that even with the bag all the way unzipped, the flap only opens about 15 degrees from closed - you'd have to pull it down to have it open the full 90 degrees. So if you forget to zip it up all the way you may not lose all the contents.

If I expand the bag I can fit my wallet, iPhone, car keys, and still have room for a granola bar, etc.

The medium size fits perfectly under the seat of my road bike. I am able to carry a hex bicycle tool, wallet, cell phone, and car keys with enough room left over for a power bar. The latched mounting strap is very secure and durable...better than velcro.

I bought the size Medium, and am very happy. What a slick bag. Very durable construction, and nice secure fit to bike. Strap under seat wraps all the way around the bag then buckles in place - this will never fall off your bike. Also velcro/buckle strap to seat post. Most of all, nice streamlined shape fits perfectly under seat w/out any parts sticking out. Very reasonable price, too!

I purchased this pack for a road bike that I use for training and racing. I ride a female specific 56 inch frame and it fits very easily under the standard saddle. When collapsed, I can fit a tube, CO2 cartridge with head, and tire levers easily. I expand it on longer rides to add a cell phone, ID, cash, and small map. I've expanded and collapsed it several times and it's still holding up nicely.
The black color helps it blend in and I appreciate the small reflective piece on the front.I have not had a problem with the zippers or closure snap - it stays on and doesn't wiggle or come undone over road terrain. I have not used it on a mountain bike or over super rough terrain, however. When I first attached it, I did have a problem with the velcro piece that wraps around the stem - the velcro rubbed on my shorts and snagged them. I tucked it in on itself and haven't had a problem since then.
All in all, I am very pleased with the pack.

Awesome bag. I actually returned it because I found them at a LBS for less, but the Avenir bags are great. If you carry more than just CO2, spare tube, patches, levers and multi tool, go with the large. I got both medium and large for different distances where I may want to carry more than just the flat kit items. Also note, I have a tri bike and the seatpost velcro piece isn't big enough to go around the seatpost, but I just zip tied it and it held fine. Should be fine for a round seatpost.

This is simply a great bag for your bike! It's plenty big and can be expanded as well. The material is high quality and it's a well thought out design. You may have to adjust your light system to compensate for the location of this bag. It holds its contents quite well. In fact, one time, I put my keys in it, somehow forgot to zip up the bag, went biking and later found out the bag was unzipped. but my stuff was still in there.

I put my light equipment in there (front and rear) along with my keys and my wallet and my bike computer and my allen wrenches and patch kit. It can fit my mp3 player in there too with the other stuff in there.

Here's what I carry in my seat bag:
Replacement tube
tire spoons
CO2 cartridge
CO2 inflator
Phone (and it's big, HTC Evo, 4.8 x 2.6 inches)
Badges and badge holder for work
small keyring
average wallet
small medicine bottle
And there's room for more, probably an all-in-one bike tool. Love this bag.

This is a very good seat bag. A well thought out design by the manufacturer.

To begin with I liked the looks of it and the medium model seemed to fit my needs. It easily accomodates tire repair tools, a Park tool, spare tube, tire gauge, mini pump, mini first aid kit, tire patches, keys and my wallet, and cell.

Only concern I had was how it would hold up in wet conditions.

Well right after I purchased it I went on a 7 day bike tour of 300 plus miles. At the first night's campsite we experienced heavy downpours from thunderstorms.

I removed only my cell, wallet and keys from the seat bag before the rains moved in.


In the morning I checked the Avenir and its interior was dry as a bone.

On the bike tour, in towns we rode through, after locking up my bike it was easy to remove the bag and take it with me while I had coffee. I found the straps that attatch to the seat rails when snapped together make a handy carrying handle for the bag.

Yeah...I have no problem recommending the Avenir Big Mouth Medium Seat Bag. It is well constructed, roomy enough for what I need to carry, and looks good on my bike.

I'll go ahead and add to all the great reviews on here for this bag. It really is a good bag for a road bike or anywhere else you need some storage without having to carry the items on your person.

The bag fits pretty neatly under most seats, hook to the vertical post and then loop the straps through the seat md back around the bottom of the bag. I can easily fit my whole fist into the bag. The flap door would stay closed even if you forgot to zip it, well sewn! The inside of the flap has a link for your keys, and a small mesh area for you to contain the keys in so they don't rattle around. The rest of the pouch is big enough for a wallet, keys, cellphone, and some bike tubes. If you happen to ride with a small side arm, (some bad neighborhoods out there!) it would fit, you'd likely have to expand the bottom with the zipper though.

Great purchase for the money!!

Big enough to fit extra tube and some basic tools and mounts securely to my saddle. Remains solid even after some aggressive downhill runs.
