It's right there.

Nothing beats the convenience of an under-seat pack. Not that they're very large, but once you have your important items stashed in the seat pack, they're there when you need them. Stash a spare tube, a patch kit, a multi-tool, and some extra chain in case of the typical mechanical failures.

Larger than expected (medium)

  • Familiarity: I've used it once or twice and have initial impressions

I was quite surprised how large this medium size is. It will hold (with ample extra room) everything I would normally carry (tube, multi tool, 2 CO2s/inflator, patches, tire levers. It is built well. It has some velcro strips on the side (inside) that appear to be secret places for cash, cards, etc. The product is built with quality materials and constructed well. Should last a long time. Looks good too.

Perfect size

  • Familiarity: I've used it several times

This is the perfect size to hold emergency tools. The construction is solid. I was afraid it might get caught up in my dropper post, but it stays out of the way. Just what I was looking for.

Does this bag have any Velcro? I’m looking for a saddlebag with no Velcro, since it can rub and damage my expensive shorts and tights!

Hey Robin! Great question! This saddle bag does not have any velcro on it. Your bibs are safe!

The reflective fabric is money!

  • Familiarity: I gave it as a gift but have feedback to share

I bought this for my husband, he's very picky about what goes on his baby (BMC road bike). After he shredded his last seat pack on his old road bike, I knew I would have to find him something that was equally stylish as it is practical and efficient. This pack in a size medium looks awesome on his bright red bike and fits a tube, toolset, CO2 cartridge and a couple packs of Gu.

Perfect size. Nice to be reflective

  • Familiarity: I've put it through the wringer

I bought the Medium size.

This fits a bar, tube, co2 setup, lights, gel, and some cash. Perfect size and no quality issues to speak of. Love it so far.

The perfect size for all the necessities

  • Familiarity: I've put it through the wringer

This bag is perfect for bringing all the necessities along for the ride. Im able to fit a spare tube, front and rear light, tire leavers and my wallet in this bag. It's nice and light as well. One of my favorite things about this bag though is how easy it is to put on and take off.


I purchased a medium.

New saddle bag

  • Familiarity: I've used it several times

Looks good, easy to use but will it hold up to the Texas heat


    Is very sturdy and like the coloring on it but...will be sending it back as it is soooo small for a medium bag.Will be ordering the large bag in this style.

    The medium is perfect

    • Familiarity: I've used it once or twice and have initial impressions

    Perfect size for a tube and tire lever, arm warmers, and even a phone. Seems to be waterproof and fits nicely.

    Good Fit and Volume

    • Familiarity: I've used it several times

    The medium tucks in nicely under the seat, fitting tools, levers, tube and cell phone, while not being too wide and interfering with pedaling. Snug attachment to the bike without velcro. No problems so far with water getting in while riding in wet conditions, but I haven't taken this through a downpour yet, either.

    Love this bag!

    • Familiarity: I've used it several times

    Everything about it is perfect for me. Very well made, exact right size, and it looks great on my bike! Fast delivery also. I will definitely buy more stuff from these guys. They have really nice bags of all types.

    Flat pack

    • Familiarity: I've put it through the wringer

    When you get a flat this is the pack you want to have on you. I can fit CO2, tube(MTB), chuck, muli-tool, and tire levers.

    Flat pack

    Pretty good

    • Familiarity: I've put it through the wringer

    Good: No velcro, good quality. The rear of the bag is a deflector but isn't sewn down on all 4 sides so I clip a tail light in there.
    Bad: The small (which is what I got) is really small so it doesn't fit much in there. Other reviewers will tell you what they fit. I stick a garage opener (no clip) and a key. Not really worried about flats on the roads I frequent.

    I'm not returning the bag because I do like it but if I had to do it again, I'd get a medium.

    Awesome little pack!

    • Familiarity: I've put it through the wringer

    I have now bought two of these. One small pack for myself and one medium size for the wife. The small pack has been perfect to fit the following and it's attachment straps are so good that it's snug into place and I never worry about it:
    - CO2 kit
    - Tube
    - Tire Lever
    I bought the medium for my wife because she likes to stuff other stuff in there like a phone or wind breaker. I would absolutely buy this product again and refer it to my friends.

    Pretty good seat pack.

    • Familiarity: I've used it several times

    Got this for my wife. She had issues with the Velcro straps on other bags snagging her shorts while riding. Best part about this pack is that there is no Velcro whatsoever. So, if you have issues with Velcro snagging your shorts, this fits the bill. The seatpost strap will be an annoyance for you, though, because the "buckle" sticks out and will hit the same part of your leg that the Velcro contacted. I cut this strap off, and just use the rail straps. Works great this way, and is plenty stable.

    The medium pack was way too big (visually, IMO) for a road bike. The small is a much better size visually, but it is narrow and long. I managed to squeeze in a spare tube, tire levers, CO2 cartridge, CO2 nozzle, and a $20 bill. This is pretty much a max load for this bag.

    The build quality seems good, and I see no reason why this bag won't last a good while.

    Great for the roadie

    • Familiarity: I've used it several times

    I got a size small for my road bike and I'm really happy with it. Unlike most other saddle bags, there's no Velcro on this one. There's a bit of shock cord and a small clip that wraps around your seat post and a bit of nylon strap with two buckles that wrap around he seat rails. I'm pretty stoked that there isn't any velcro to worry about he ends/corners creeping out and scratching up my legs. The shape of the bag is longer and narrower than most other ones I looked at. It can be a little weird depending on what you're trying to cram in there but it does a really good job of staying right under your seat and not sticking out beyond the saddle at all.

    The size small is great for my road bike - fits one tube, C02, and an inflator head. There's (barely) space to shove a key in as well. If you're looking to carry your phone or use this on a mountain bike I'd suggest sizing up. I've had this for about a month so can't say too much for long term durability, but it seems like it is built well and should be able to hold up just fine

    Not great

    • Familiarity: I've put it through the wringer

    It did not last long on my bike. The plastic bits broke off and the whole thing started to fall apart. When it rained, water creeped in on the sides. Overall I would not reccomend.

    Good Quality, Medium Quite Spacious

    • Familiarity: I've put it through the wringer

    I needed a bag for my commute/errand/city bike. I have a rack on it that can carry bigger bags, but I don't always keep that on it and I wanted to have a tube, tools and the like should I need them. I got a medium in white. I was able to put a 26"x1.9-2.1 tube, Park Tire Levers, a Park multi-tool and still have enough space to throw in my billfold should I need to.

    If I were using road tubes, I could easily swallow two and those tools.

    It attaches easily under the seat and so long as you snug it in place well, it stays put without issue.

    I like the white because I can tell quickly from a distance that it is closed. So when I'm walking away from it at a store or wherever, I know I remembered to zip it after grabbing my wallet and locking everything up.
