One of the best things about owning ultralight backpacking gear is the incredible level of customer service that you receive from the small cottage industry of gear manufacturers that make this type of equipment. If you need advice or your gear needs to be repaired, these manufacturers are easy to contact and will go out of their way to help you out. These companies will treat you like a kindred spirit, not a bar code, like some of the larger gear manufacturers out there.
To give you an example, I own a Starlite backpack from Six Moon Designs. I'd used this pack pretty heavily and it was literally coming apart of the seams. This is normal with ultralight gear: there's always a trade-off between weight and robustness.
So, I contacted Ron Moak, the president, head designer, customer service rep, and webmaster of Six Moon Designs and asked if he could repair my pack by re-sewing some of the components that had torn or come apart. I was perfectly willing to pay for these repairs because I love this pack so much, but Ron immediately volunteered to repair it for free. He didn't even ask me to pay for the return postage. I did anyway, but that's pretty incredible customer service, isn't it?
