From first picking it up, this bottle has a heavy, sturdy design. Most of the bottle is covered in a grip so I’m not worried about it slipping out of my hand easily even while sweating. There’s also a plastic loop that flips up for hooking the bottle to bags, lanyards, etc that could also be held onto in addition to or instead of the main grip. The lid is tight fitting and when my hand is slick trying to twist it open, I use that side flip loop to get it started. For drinking out of, it’s an easy twist open and shut open circle for easy flow. I was worried about how to thoroughly clean the lid mostly the inside of the mouthpiece with the twist design, but to my surprise, the care tag has step by step instructions with pictures to disassemble for cleaning and put it back together properly. This bottle looks great, feels great with the bumpy grip with puffed out bolt design and printed logo, and I foresee this lasting a long time. Much preferable to lightweight thin bottles that crack or wear easily.
