Our swirl tie dye collapsible water bottle is so. stinking. cool! Not only does it feature a super cute rainbow-colored tie dye design, but this silicone water bottle is collapsible, making it absolutely perfect for hikes and other adventures. When you're finished hydrating, you can squish it down to half its normal size and tuck it in a backpack or hook it on with its handy carabiner. It makes a great gift!
