We'll let a customer review do the talking for this one:

Just finished a race sim and for some reason I’m thinking about the clothing. It’s soaked, obviously. Everything is. But it never felt heavy during it. Weird. You only realise it after, when you’re standing there trying to breathe normally again and you notice it didn’t really stick to you the way other kit does when things get ugly. It stayed open. Through the heat, through the stations, through that middle section where everything starts to blur a bit and you stop caring what looks good and just try to keep moving. It's like air was getting through it the whole time. Not in a noticeable way, just enough that you weren’t fighting your own sweat and temperature as much as you normally are? 

Even now, pulling it off, it hasn’t gone weird. Fabric not stretched out in a way that makes it feel finished. It looks like it could go again. I can’t say the same. That’s the thing with it. It didn’t feel like a limiter at any point. It just worked while I tried to get through the session. George has said Elite 15 athletes have been putting it through that kind of work for a while now. Long sessions, race sims, repeat efforts where everything else starts to fail first. It holds up better than I do. THANKS FOR MAKING AWESOME KIT. - Harry
