It is indeed comfortable
Size: Large 1/2in x 6ft-Rope Clasp, Color: Light Blue
I really like this leash. The color is vibrant and I have experienced zero fading even though I leave it outside. I really appreciate the padded handle and the entire leash is a good substantial weight - I hate a flimsy leash. I would not hesitate to purchase this again if needed.

Picky dog approved!
Color: S6-muti-color, Color: S6-muti-color
I have wasted so much money on dog balls that they won't even pick up! They finally were obsessed with the Kong rubber green/blue or red/blue ones, but they're $3+. each, and they break from the dogs squishing it. I honestly had zero expectations on these, and they BOTH picked them up on the first throw! That's huge!! Seem to work fine in the ChuckIt. As for the squeaker, at first I was like "Oh nooooo." when they both loudly started! Much to my (and my neighbors') happiness, the squeakers stopped working after a couple minutes. 🤣
