Fits good in my Lab's Approach pack. Holds a ton of food. Packs down great when needed.Good for overnighter's or 3 or 4 day trips.
Nice water bowl. Just like the cinch top without the cinch. All Ruffwear stuff is top notch. I got the large and it is HUGE holds about 2.5 quarts.
I will say I really liked these boots and wanted them to work for me. Everything felt great except the toebox was a little narrow for my foot. Not overly narrow, just enough I could feel a rub on the little toe when going downhill.My feet aren't wide usually wear a D but were just a bit to wide for this boot. I would still recommend trying.
