Exercising Demons Insulated Bottles

Color: White

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.

Customer Reviews

Based on 21 reviews

I bought all three, one for me and two for my exercise buddies. We all love them, not only for the hilarity of the design, but they keep your drink cold (or hot I suppose) quite well. And the demons ward off injuries from that extra 30 lbs you added to your dead lifts trying to impress you-know-who, who really was not impressed by that, but is impressed by your good taste in a water bottle.

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

Devishly fun

My husband loved his exercising demons drink bottle. Says it keeps his water cold - even in infernal temperatures.

It was a gift, calamity red water bottle

My daughter is totally delighted with her present, and seems happy with all about it... the way it looks and works and the size is just right. More water! Thank you.

Demon water bottle

My exercising demons water bottle is the greatest. It keeps my cold drinks nice and cold, the ice lasts a long time. It’s fits in most cup holders too. Plus I get compliments on it a lot.

Lid Design

I absolutely love your items!! Seriously, you are my people. I would love to have a lid that provides the option of allowing me to use a straw myself. I will likely purchase one regardless but, if you have that type of lid please let me know. Thank you!


Love love love


the lid broke for no reason


So fun!

Great Product

I absolutely love all their products, but I especially love these bottles. They keep drinks cold and I even have had ice still remaining in the bottle overnight. Excellent product!
