Bikepacking Bag Waterproof Bike Saddle Bag Large Capacity Bikepacking Seat Bag Road Mountain Bike Seat Bag

took this with me on the munda biddi trail for a 2 week solo ride and it was brilliant. when packed full, this can sway a little which was very easy for me to fix with 2 occy straps.

This bike touring bag has completely exceeded my expectations. First and foremost, it is truly waterproof — not just “water-resistant” like so many others claim to be. I’ve ridden through heavy rain and everything inside stayed bone dry. That alone gives me huge peace of mind on longer trips.The build quality is exceptional. It feels incredibly sturdy, with tough materials, reinforced seams, and zippers and buckles that are clearly made to last. It’s also surprisingly comfortable to ride with. The design hugs the frame perfectly, and there’s no annoying sway or rattle, even on rougher roads or gravel.One of the smartest design features is how it keeps the center of gravity low. That really helps with balance and maneuverability, especially when climbing or handling tight turns with a fully loaded bike. It feels stable, secure, and natural — you almost forget it’s there.And it’s spacious! I’ve packed gear for multi-day tours with no problem. The layout is intuitive, making it easy to access essentials without having to unpack everything.In short, this bag nails it on all fronts. It’s rugged, waterproof, well-designed, and a joy to tour with. Highly recommended for anyone serious about bikepacking or long-distance rides.

I’m new to the bikepacking scene so I wanted to find something to let me try it out without breaking the bank. Enter RockBros bags, a great product for a great price.I just finished a three-day trip on the Great Allegheny Passage (GAP Trail), and these bags were awesome! In fact, better than awesome. On Day 1, it rained. The. Whole. Time. Like downpour rain. When I got to my destination, I was skeptical about whether my stuff would be dry. I needn’t have worried. When I opened the bags (I have the half frame bag, too), my stuff was dry as a bone.There are a couple of nitpicky things I noticed. For example, it’s tough to find the right way to pack the bag because it’s so narrow by the seat (but, silver lining, it allowed for an inexpensive seat-mounted water bottle holder that also functioned as sort of a sway bar), and it tended to sag a bit in the back when it was loaded with stuff (which I sort of figured out by Day 3), but those were minor issues in the scheme of things.In the end, I’m telling you, when they say “waterproof,” they mean it. I’m super happy with my purchase and I would purchase more RockBros products in the future.

Looking forward to my first bikepacking trip with these RockBros bike bags

I received what I think is the third version of the bag, as the attachment under the saddle is reinforced but not with metal grommets. I really wish I had received the second version with the metal grommets, because about three weeks into my bike touring trip it started tearing. It got worse over time, but thankfully I was still able to make it home before it fully tore off.The bag is great in that it is waterproof as described, but it really is lacking in the area of durability.UPDATE: RockBros just sent me the previous (second) version of the bag with metal grommets. The grommets go all the way through and I can feel them from the inside, so I'm certain this new bag I received won't have the same tearing problem as before. Not sure why they "upgraded" to the third version without the metal grommets as it holds the bag together better---maybe it looks better? Regardless, I'm very impressed with their customer service as they had to contact their factory to produce this version of the bag for me. I definitely would not hesitate to buy their other products in the future with the way their customer service has treated me.
