Overall I am satisfied with the product. The yerba mate is quality and it does have a strong bitter taste but a little honey makes it palatable until you get used to the taste. I haven't traveled with it yet but the backpack and thermos are of good quality and so is the gourd. I just feel it's too small so you end up wasting allot of your tea because there's not enough room in the gourd to pack the tea in properly to prevent from soaking all your leaves at once. I am not sure if I would buy from this company again because the box was severly damaged. Products looked ok though
