CamelBak Forge Flow Coffee & Travel Mug, Insulated Stainless Steel - Non-Slip Silicon Base - Easy One-Handed Operation - 16oz, Moss

I usually just use it for water but it keeps my water nice and cold and it's also the perfect size for mixing in flavored water packets that I use to hide the taste of my creatine and other supplements. I've never had a spill (though you do have to be careful to let the lid close while still drinking so you don't leave the liquid on the outside of the seal). I also really like that the bottom is padded with rubber so it doesn't make a bunch of noise when I set it down. I liked this so much that I purchased a second one to leave at work. So one goes back and forth from home with me in the car and the other stays at the office to get water from the cooler to avoid wasting water bottles or cups.

Thinner so very easy to handle, keeps coffee really hot but what I like the most is the lid (mouth piece). You NEVER spill when you’re sipping even on bumpy roads.

*** Updated Feb/2025 - LEAKS coffee if sip-switch is open. A feature that was cool sounding in a R&D meeting, but in real world use, it’s terrible. I just drained a whole coffee in my back seat because the cup wasn’t perfectly vertical and the sip with was open (it’s hard to see if it’s locked or open). I do not recommend this mug.It’s smaller ounces than our previous coffee cups, but probably the right amount. One of ours came damaged and we made a claim with the manufacturer and they were quick to respond and sent a new cup out quickly. The Amazon shipping was the cause of the damage, not the durability of the cup.There is a switch on the lid that keeps it open, so if you put the mug in your bag, it will leak.

Plastic is more brittle than that of my older one. I do not see this lasting as long,5 yrs.,as my older one. Good but not outstanding.

i think the opening for sipping can be bigger, but that’s nit-picking.

This mug seems to be watertight when closed. When the lever is pressed two ports open: one in the front for drinking and one in the back for ventilation. When the mug is full, if the mug is tipped more than the absolute minimum for drinking fluid will enter the vent system and subsequently spill.

Today finally tossed this thing in the trash. Every where it went it leaked and made a mess. And just using it normally without it getting kicked over etc.Couldn’t really figure out where it was even leaking from. But somehow coffee always ended all over the place.

Insulation is fine. Finishing is fine. It's pretty.However, the button is hard for me to press. Not sure if it's the positioning or just a hard button.Also, it does not lock _shut_. You can lock it open, but not shut.So it's pretty easy for it to get pressed on and leak.
