This is also the easiest drysuit I’ve ever flown. Just as a test, I flipped fins-up and waited for the air to rush into my legs. I wanted to see how easy it was to backpedal out of the position and recover.
The result was really, really unexpected – the air just kind of meandered into my feet. The lycra controls air movement! After a while kind of hanging there I got bored and flipped back level. After some reflection, this worried me, because I often cruise along with air in my feet to keep them warmer, and I wasn’t into something that would prevent it! So I tried it, without a problem, if anything it’s easier to meter how much air goes into the feet.
