    Great bag for the minimalist
    by Anonymous

    Light, waterproof and almost invisible under the saddle. Holds one tube, two CO2 cartridges, two tire irons, CO2 pump head and a small wrench. All that is needed for most rides. It sure beats most other larger, heaver bags.

    This bag carries the essentials needed for a flat fix. It leaves room for my Garmin Radar light on my short seat post.

    Tiny is the new medium

    Once you go tubeless on a road bike, as in not carrying a spare tube anymore, your old saddle bag is suddenly obsolete and oversized. This bag is perfect for the essentials. I have a CO2 inflator and two 16g cartridges, two tire levers, a minimal multitool, and two variations of tubeless darts, all nicely arranged in this little bag. It sits quietly and is easy to clean. The only downside I've noted is that the velcro on the strap wants to split. I've glued it back down for now, but at this price, I should probably just order a couple more bags and plan on a year each.

    A Great Little Bag
    by David K

    The Undersaddle Mini Saddle Bag is light, adequately water proof, and just big enough for the essentials a wide road tube, a CO2inflator, some tire levers, and an emergency $5 bill. The size is small enough the bag completely sits underneath and within either side of saddle. I recommend this bag to anyone who wants a reasonably priced, minimalist saddle bag.

    Great small bag
    by Anonymous

    I'm using on my Venge with aero seatpost. It works awesome and it's very small but enough for 1 tub, 1 CO2, a chuck and that's about it

    Best smallish bag out there

    I hate big, clunky saddle bags......However, there are a few items that every a avid cyclist should carry. Tube, inflato, co2, lever, etc. This bag is made well, looks good on the bike, and simply works.....
