Exercising Demons Insulated Bottles

Color: All 3 Colors

Shipping and taxes calculated at checkout. Free U.S. shipping on orders over $200.

A sturdy, insulated, 24-ounce stainless steel water bottle decorated with a dignified pattern of demons engaged in wholesome exercise. The design is available in three color choices—red bottle with black demons, black bottle with white demons, and white bottle with black demons. Bottles have a glossy but textured stainless steel finish.

Bottles are constructed with an insulating vacuum layer sandwiched between two layers of premium stainless steel. Miraculously, cold beverages stay cold and hot beverages stay hot (not at the same time). Tests show up to 6 hours for hot coffee and up to 24 hours for water with ice.

Screw-on plastic top won’t leak when you tip your bottle over at the gym. Flip-up sippy spout and removable, interior straw allows you to drink without removing the top.

How can a bottle be so confusing?

I got the bottle on Kickstarter. It doesn’t hold a lot of water to begin with, but when it gets down to maybe 1/3 empty, the liquid stops flowing. It took me a bit to figure out that I have to put my finger over a small hole in the lid and suck to get the liquid out. Poor design for a sports bottle. The devil is in the details, I suppose. I’m not really thrilled with the bottle itself, but the artwork is fantastic!

This seems wrong, so my hunch is that you received a defective lid. I've been using my water bottle for 6 months now and have never had that problem. We'd like to send you a new lid/straw combo, as I suspect that will fix this problem. Can you please contact us at so we can take care of you?

Love my new demons

I just got my insulated thermos' & they look terrific. The size, colors, patterns, ease of lid use, cleaning ease, make them a big hit for me. I use insulated mugs and cups every day for hot & cold drinks and these demons do it all. I can get rid of all my old ones now. Also they almost, almost make me want to get off the couch & lift weights
