## Questions & Answers

**Q: Is the M big enough to store my wallet and my iphone 8?**
A: Will easily hold that and surprisingly more. Also kept everything dry in downpour.

**Q: When I put my bike on my car bike rack will I need to remove the bag to put the straps over the cross bar?**
A: Yes you will have to remove any bar bags as they will interfere with most racks for mounting. You can always get around this by moving the bag to a different part of the bike but then you have to affix it back when riding for functionality.

**Q: I have the iphone 11 pro max, can i use this case to store this phone?**
A: I have the iPhone X and it just fits.  Based on what I now of your Phone, it is going to be close, maybe too close. I would look elswhere

**Q: Would the medium bag be too large for a child’s mountain bike?**
A: Childs department store bike with buzzliteyear on itn? No. Youth mountain bike? Yes. Should work just fine. Prolly make some kid real happy and turn them into a pro bikepacker. After all thats the key to adventure. Never grow up and always play in your planet!

### ⭐⭐⭐⭐ Almost Perfect, Except For It Shifting
*by D***E on March 29, 2019*

I was thrilled to finally get this because this type of bag is the only type that can actually fit on my MTB without it getting into the way. I can't have a saddle bag because I have a dropper, and when I drop my seat all the way, it gets really close to my rear tire, which will then rub when I'm on some narly techincals. Then my bike geometry is in such a way, I can't put one in the bike triangle..... since my shock gets in the way. Thus, this seemed like the perfect solution. To be honest it mostly works but I do have one gripe... PROS: - Large enough to put a ton of things in but not so large that it looks like a hiking back pack. - Good solid material. Took on rain and mud and it held up. - Solid velcro straps. They strap and don't come lose. CONS: - This is where I'm bummed. While the straps are great and keep it in place (mostly), the bottom strap, that straps to the top tube is not very well designed. The strap itself simply slides through a couple of slits on the bottom of the bag, which means, it slides around. Even with the strap tight and firm in place, with just enough force, you can shift the bag left / right. I experienced this on every ride thus far where I'd make sudden turns, or quick endo's , or take really fast burms.... think of the effect of a Centripetal force. So what happens basically is the bag is now greatly shifted to one side off the top tube, which causes to slighly slag downward, which then gets bumped by my knee. Sucky!
