Just gotta say this thing is comfortable, it stretches a lot so it can easily fit around. Only thing I’d do is if you are on the borderline between sizes go down. I usually wear a 1” with the mos sleeves but this won’t stay tight enough and my glans will retract. Just ordered the .75 and gonna use this 1” as my new pumping sleeve. I also got the durapro so gonna see how long it will last for hanging.
