The Boulder Insulated Water Bottle is our flagship thermal hydration vessel that will keep your beverages hot or cold all day long. Made from food grade 18/8 stainless steel and featuring our signature TriMax® triple insulation technology, this vacuum insulated water bottle is tested to keep liquids cold for 36 hours and hot for up to 10 hours.
The Boulder insulated water bottle features a food grade stainless steel removable strainer for tea and fruit infusion. The strainer will also work well as an ice dam to keep your ice in the bottle instead of your teeth. The Boulder includes a multi-lid top with a wide opening for filling and a narrow mouth for drinking and is interchangeable with our coffee and flip straw tops. The two-piece lid includes an integrated carrying strap and its secure leak-proof seal will keep your drink inside the bottle where it belongs. It’s available in a variety of colors and styles in our durable powder coated finish or in a stainless steel finish. This insulated water bottle won't sweat and will fit most cup holders. Toss this insulated bottle in a tote bag, bring to yoga or hit the trails. Whether you are at your desk or running errands around town, the Boulder will keep you hydrated.

Absolutely love the eco vessels. The fact they last all day cold is so great. I take it everywhere and don’t drink my water out of anything else. Previously had a taller but narrower one, fitted more in it , which I did prefer but still love the new one.
I am a keen Pilates Student and I love taking herbal teas with me to classes. This is the perfect size bottle and my drink stays hot for ages!
The perfect size to take to spin class! I don't like guzzling those public drinking taps at the gym so I always make sure I have my Eco Vessel with me :)
I love having my smoothies every morning and this bottle is the perfect size and keeps my smoothie icy cold and super fresh!
AWESOME PRODUCT, EASY TO USE AND ALWAYS KEEPS WATER NICE COOL AND FRESH.
Fits in the cup holder and perfect for those long drives!
I did a lot of research on water bottles before buying these. My criteria was: stainless steel, needs to fit ice in the top (most waterbottles and too skinny to fit ice in the neck) and needs to have no straw or equivalent (too many mouldy straw episodes!). This bottle ticks all the boxes, plus is well insulated but not too heavy. We have had ours a few weeks now and are very happy.
