  1. Pricey, but worth it!

    By GalenaNightfire

    I bought both the Seatpacker 9 and 15. They are the only seatpacks that work on my XS carbon frame. I use the 9 for day trips in winter weather to carry all my layers. I use the 15 for UL touring (paired with Revélate frame bag and Sweet Roll). Yeah, ya gotta pack light, and wash out yer bibs each night, but it makes for pleasant days of riding without all the extra weight of panniers(and the extra crap you'll shove in them, just because you can).

  2. Very good for light road bikepacking

    By Martin

    I bought this bag to use in addition to a half frame bag when I do light touring. I put tools, repair and nutrition in the frame bag, and keep the seatpacker for cloths and lighter items. It works perfectly. The light frame that hold the bag does a very good job at keeping the bag stable. I can even stand on the pedals when doing steep climbs. I bought this product for that very reason and I am not disappointed. It does work. I find it pricey for a bag but at least the quality is there.

  3. Perfect

    By Nicholas

    This bag is simply perfect. There is no movement even if you rock the bike back & forth on a steep climb. I've biked across the country w/panniers. This and a front bag & frame bag is all one would need in the summer.

  4. Great Bag!

    By ADKer

    I purchased the bag for a 3 day ride around Lake Champlain. We'd be moteling it so didn't need huge capacity. It worked perfectly on my Specialized Rubaix road bike. What impressed me the most was the total lack of tail wag, ease of mounting and removing, and total waterproofness. It poured rain the entire first day (66 miles) and the contents of the bag were bone dry. Great bag that I can use for long day rides where I can carry my and my wife's rain gear and lunch. Didn't get 5 stars due to $200+ price, so perhaps not the greatest value. but that said, maybe top quality and functionality are worth the price!

  5. Excellent

    By corakeen

    My experience using this seat pack has been outstanding. I'm here buying them for the rest of my family. Thanks for making something that works!
