I have used this pack on a few multi day trips since I got it late January. And overall, I’m a big fan. But it has had a rubbing noise from the top where the frame meets fabric and strap tighteners. After a few miles I want to here nature and not the ong rub noise. I emailed support to find out if there’s any possible resolution. I don’t fault for the customer service rep Hillary for pointing out that the original drop description did not feature any warranty, so after Massdrop’s 30day policy, I’m out of luck. But it does mean for me that I’ll go back to making most outdoor purchases through REI where I know I can walk in with a product I’m having a problem with, and walk out with a replacement or have it sent in for repairs. I guess for little things where durability is not a key concern, I can still have fun shopping around Massdrop.
