After studying hundreds of water bottles in the design process for the capCAP, we know a thing or two about what makes a great bottle. casq combines seamlessly with the capCAP, both functionally and aesthetically. There are two sizes, two finishes, and three capCAP colors so you can carry the casq that suits you best.

An insulated water bottle, for humans.


Both the 20 oz and 30 oz casq are tapered to easily fit into cup holders and slide into pockets. This slim design also makes them easier to hold without sacrificing capacity. casq wasn't just designed to look cool though, it was also designed with purpose. That's why the casq is vacuum-insulated and double walled--this keeps your cold drinks cold and your hot drinks hot. This also prevents the bottle from sweating. The rubber bumper also adds functionality while keeping your casq looking new--the bumper helps your bottle resist dents and dings.


The perfect bottle also deserves the perfect cap--that's why the casq combines seamlessly with the redesigned capCAP. The new capCAP has all the same great features as the old capCAP--splash-free spout for easy drinking, wide opening for cleaning or adding fruit and ice, comfortable strap for carrying. It has some new features too like the "Cap Keeper" that holds the small cap out of the way when you're drinking and smooth, rubberized grips on both the small and large caps.

Can I use my casq with both cold and hot beverages?
Yes. Yes you can. casq will keep your iced beverages cool for 24 hours and your hot beverages warm for six hours, which is the industry standard for insulated, stainless steel bottles.

How do I clean my casq?
The bottle portion is designed to be hand washed with warm, soapy water or warm water mixed with baking soda. Then, air dry the bottle with the lid off. The capCAP is dishwasher safe.

Can I put the casq in the microwave and/or freezer?
Nope. Sorry. Don't put it on the stove top or in your oven either.

Will this fit in my car cup holder?
casq was designed to fit in standard cup holders to make it easy for transport. You can find the diameter for reference in the above specifications.

I hate it when my water bottles sweat. Will the casq sweat if I put ice in my beverage?
We hate that too; that's why the casq is constructed with double-wall vacuum-insulation that stops bottle sweat.
