Handy tips: Don’t put sleeves in the washer or dryer. We encourage you to dip, soak and hand wash any sleeve on their own.
I had the 2.0 for years and loved it, but I decided to try out the new one since you don't have to change out valve and it's adjustable right there and then. I am really happy with it and makes working out a workout.
