Don’t worry guys, this message has nothin’ to do with the adverse effect of freezing potholes on human anatomy; but is rather a scientific research report of some interest to us all. Anyway,I recently stole a deal of a rope right out from under Ram’s Prize Nose, by throwing in promises of some prohibition beer from the Far White North (sorry, Ram, you guys can have the real stuff anytime you want – but we Utahans are an easy target for this kind of bribe). It is a beautiful Petzl (some hint of the Easy Target Person here) static rope – my very first – and measured in at 507 feet. I briefly considered a White Elephant Christmas Canyoneering Prize for the closest guess to the length after it’s first wash and dry; but I’m just too lazy to do anything but just give you the answer of 501 feet – a mere 6 feet lost! I was surprised by this after all the reports of people complaining that their Heaps rope “must have shrunk since they bought it” etc. etc. So, there you have it – real science brought to you by Alicia. Guess if it’d been just a few feet longer, the prize could of been the first 1 stage rapel from Heaps!

Good point. I’ve also heard that some folks have a serious problem with shrinkage in really cold water.

I have not owned a Petzl rope yet, but some of my others did not shrink all the way on the first dunking … in fact it required multiple dunkings over a period of time to reach my current pathetic state of shrinkage.
Hoping yours shrinks less than mine! Neil

Alicia, it’s a PMI rope!
