I often swim in the morning, then leave my wet swim gear in the car. I occasionally swim with Roka Sim shorts and have also left them in the car (mild weather between 45-70). Now that it’s getting colder I’m curious about leaving the Sim shorts in the car when it’s below freezing. Will that lead to damage?
please give it a try. i want to see what happens. if there is a problem, we’ll replace your shorts. i wouldn’t advise doing this generally and am not extending the offer to all of ST, but am open to testing it out here to see what happens. 
best,

How cool is this!! ROKA, you guys rock
awesome!
How did this work out? Since we’ve got a few months of freezing weather left where I am, I’m wondering the same thing.
I have done this with my Roka Sims.
Last week I left my bag in my truck for a couple of days and when I pulled them out they were a frozen block and inflexible. In fact ironically my old pull buoy was frozen to them as well. I just pulled them out of the bag and let them defrost. I have used the shorts twice since them with no problems. Not sure of the long term effects at this point.
I have a cottage in Canada and everything in it goes below freezing many times throughout the winter. I have various wetsuits, clothes, bikes, shoes, etc. Everything works just fine every summer.
