## Questions & Answers

**Q: What's the maximum weight that it can hold?**
A: Not sure off weight capacity although for 8 days I had it totally stuffed

**Q: Can you fit a pair of jeans and a shirt in the bag?**
A: Yes there is sufficient space for a pair of clothes. I typically put my dress shoes and my lunch into the bag which is probably the extent of its capacity.

**Q: Will it fit a usgi sleep system in it ?**
A: I do not know the size of the usgi sleep system. Check out the volume of the bag you are looking at. I do not have the bag with me now to measure it. It is very large though.

**Q: Any funny feelings when riding a road bike with a fully loaded bag ?, Balance issues ?, Other ?**
A: Haven't yet had this bag on my road (gravel) bike...only on my mt bike. That said, its quickly apparent you have more weight up HIGH on the bike (to be fair I also had a handlebar bag and a top-tube bag...so I was carrying about 25 extra pounds total)...when you first start rolling you cant help but notice the extra weight, and how high-centered you now are (as in, a little slip of the front wheel and you would be down before you knew what happened). So its all about being smooth and balance...kind of like on rollers (where one slip can be disaster). Quite honestly it doesn't take long and you can easily forget about how heavy your bike is...you do want to TRY to put your heaviest stuff as low in the bag as possible (I keep my jet-boil down near the very bottom). Its a GREAT BAG, enjoy the ride!

## Customer Reviews

### ⭐⭐⭐⭐⭐ Outstanding Bike Touring Bag – Built for Real Adventures
*by S***N on May 12, 2025*

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.

### ⭐⭐⭐⭐⭐ Pumping momma-awesome bag!!!!!
*by K***E on May 20, 2023*

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.

### ⭐⭐⭐⭐ Still lacking in durability
*by B***Y on April 26, 2019*

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.
