    Water Bottle Braze-Ons vs. Frame Storage?
  

*by A***R on Reviewed in the United States on May 8, 2023*

I ride the sky-islands, Arizona high-scrub desert, where the wind is always blowing 15-mph in your face. I love my panniers but wanted to cut down on wind resistance for day rides; but I also love my water bottle cages, where I usually keep 32- and 24-oz insulated bottles of cold water and caffeinated electrolytes. With the frame bag fully extended, I sacrificed one braze-on, but even with that bottle stored in the frame bag, I had a net gain of almost 2-liter of additional stream-lined storage. And the small zip pocket opposite the main pouch is great for a pump, multi-tool, wallet, and backup light. The bag is well-made and the flexibility of the webbing strap placement is impressive. I've always been a rear-rack trunk and panniers rider who scoffed at the bike-packing bag craze. But I'm now convinced, with the proper bike frame, that sacrificing a bottle braze-on is a reasonable trade-off for frame storage. Only the next few thousand miles can test the bag's durability. I may not be a complete convert, but for now, I'm quite pleasantly surprised!

    Quality bag
  

*by M***K on Reviewed in the United States on June 28, 2021*

Great bag, great price. High quality. It’s not flimsy. Holds its shape well. Very adjustable. I have a medium frame gravel bike and it fit perfectly. If you have a large it should still fit just fine. It’s a good size.

    Great bag for the price
  

*by J***R on Reviewed in the United States on September 2, 2020*

Works great for all-day gravel bike adventuring. Replacing the top Velcro straps with laces will help keep it from sagging; thankfully the existing webbing on the top accommodates this.There may be better bags out there, but none that I’ve seen at this price.
