Sizing Not Very Accurate
"I ordered this vest hoping to use it for hiking and trail running. That being said, I hoped to be able to use the 12 liter capacity to my advantage. However, after measuring my chest size and checking the size chart to get what I thought was the right size, the vest came in and was fairly tight even when empty. I tested putting a couple of things in the back then trying it on but it was now way too small. I'm pretty upset that Mammut doesn't offer exchanges on here because I was unable to properly field test this product."
