ROCKBROS Bikepacking Bag Waterproof Bike Saddle Bag Large Capacity Bikepacking Seat Bag Road Mountain Bike Seat Bag Max 14L

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.

This bag is AWESOME!!! I have a newborn but still like to go on long rides to stay active. I could fit my Medella free style pump, flanges, 2 bottles, a milk cooler that comes with Medella pumps, my windbreaker..and there was still more room to shove things in there! The bag didn’t bounce around or hit my tire, very sturdy and secure. Also liked how I could attach my safety light to the back, just felt like my light could fly off so had to rig it a little bit, that would be my only complaint. But can’t get over how nice and sturdy this was. Definitely recommend!!!! Very impressed.

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.

I have had this bag for several months and have taken it on a few bikepacking trips. I am pleased with the design and construction of the bag. I haven't used other seat bags, but the construction seems to be on par with the (much) more expensive bags out there. The material is nice, waterproof nylon. No zippers on this, which is great. It is quite stable on the big when packed properly. One design critique is that the bag is very long - this is OK because you just don't fill the bag up all the way and then there is plenty of room for the roll top, but when filled all the way it is quite the rocket. I like the placement of the reflective loops which are perfect for mounting a tailight. Would buy again!

I'm really amazed at how well made, sturdy and well fitting this thing is. It is also huge! I have used borrowed top of the line bags that cost twice as much to try out bikepacking. Now that I'm getting into it I just could not see spending that much so got a complete Rockbros set. This piece is just as well made as the much more expensive one, if anything the critical nose of the bag is sturdier. The included foam insert that fits against the seat post means you can pull the support straps really tight and get a snug fit. If you really cinch up the straps that go through the seat rails real tight you will get very little wiggle even with that huge tail piece sticking way out behind you. Only downside, probably weights a hundred grams more than the high end one I had used before.

After reading the mixed reviews I decided to purchase it anyway. Once I received the pack I looked it over and took note that all the points of connections had been reinforced and had extra stitching and the pack as a whole seemed sturdy. My only concerns were that the plastic buckles seemed a bit light weight for its intended use. There was only one way to find out so I loaded it up with my gear and went out on a trial ride on my local trails. A mixture of gravel fire roads and technical single tracks. At first I was pleasantly surprised at how steady and secure it felt. There was some sway left to right but not enough to throw me off balance. All was good. An hour into my ride I noticed that the pack seemed loose so I re-tightened the straps but shortly they were loose again and eventually one of the buckles broke. Fortunately I was able to tie the two ends together and make it back ok. Once back home I noticed that the material where the strap attached to the top of the bag had also torn but I assume that the stress from the other strap had broken caused the tear. In an attempt to save on weight and cost they went with cheap quality plastic parts. They really need to make sure that ALL the components are rated for their intended or potential use. This pack is less expensive then other products and some would say that you get what you pay for but this product is of good quality and well worth the price but it still needs a little tweaking.
