Here at Hydro Flask, we strongly believe in “treading lightly”. Our environment is our everything, and we wouldn’t mind if it stuck around for a while! With that said, we also believe it is an important aspect of human nature to “leave our mark.” Now, I don’t mean “leaving a mark” in the sense that a vandal might leave a mark. Instead, we as human beings, naturally want to leave our mark in a positive manner! And fortunately for all human beings,Hydro Flask compliments both of these virtues! You can make your mark and still tread lightly!
In addition to being in-tune with human nature while becoming a key gear-item in the quiver, the Hydro Flask naturally heightens our subconscious awareness of hydration-levels*!
We at Hydro Flask believe that we are “making our mark” in the industry by offering double-wall insulated, BPA free, stainless steel bottles that you will be thirsty to use! And isn’t it nice that we don’t object to you making your mark on our bottles? In fact it is encouraged! So go ahead and stick one of your favorite stickers on it, send us the pic, and we’ll post it on our Flickr site!!
I remember the “leave a mark” concept quite well. It was one that sent me on a deep pondering about the nature of the human spirit. It was taught to me that when we see a fresh blanket of snow, we naturally want to walk in it. Or that when the water from a wave recedes back into the ocean, we naturally want to go make our sand-tracks in its wet trail. 
There is a fine balance between “treading lightly” and “making your mark”. This a balance that Hydro Flask espouses! This is a balance we encourage! So refill your bottle and go make your mark! And remember to tread lightly like we do!
