Stackwell is a 3-in-1 stainless steel system built around a 1000 ml, about 33.8 fl oz, double-wall vacuum insulated bottle, with a 270 ml water bowl and a 250 ml food bowl that nest onto the base for travel and detach separately when your dog needs to eat or drink. A leakproof flip-up lid keeps the reservoir sealed in a bag, and the food-grade 304 stainless steel across all three pieces wipes clean and resists rust, making it a reusable alternative to packing single-use bowls on hikes, outings, or vet visits.
Packing a water bottle and two bowls separately means digging through a bag at every stop. Stackwell nests both bowls onto an insulated stainless steel bottle, so the whole setup travels as one piece and separates in seconds when your dog needs to eat or drink.

A 1000 ml, about 33.8 ounce, double-wall vacuum insulated reservoir keeps water cooler for the trip.
A 270 ml water bowl and a 250 ml food bowl nest onto the base and lift off separately when you stop.
A sealed spout keeps water contained in the bag until you're ready to pour.
Every piece, the bottle and both bowls, wipes clean and resists rust with regular use.
Before adding another travel bottle to the bag, it’s fair to ask if the bowls actually stay put, whether it’ll leak, and if there’s enough water in there for a full outing. Here’s what to know.
Give the lid a quick check before every trip. The seal is what keeps the reservoir from leaking into your bag, and it should click fully closed each time you fill it.
