Tossed this in my back pocket on a hike and barely noticed it was there until lunchtime. The silicone wipes clean in seconds and doesn't hold onto kibble smells, which is more than I can say for the old plastic bowl.
The collapsible design is the best part—they fold down to almost nothing and slip right into my back pocket on walks. Didn't expect the silicone to feel this sturdy either, no weird smell after weeks of use.
Tossed these in my daypack for a weekend trip and barely noticed the weight since they collapse down flat. The silicone wipes clean in seconds at a rest stop sink, and the bamboo rim holds its shape when my dog drinks.
