5°C 260° forecast looked OK for a nice "formula" session on the biggest gear, but got caught inbetween two squalls, just missed the first one, and the second one was a tad too agressive to make the most of it. Especially wanted to try the Ianovated double lined wetsuit. The breathing system and semi-dry aspect (the large wrist and neck cuffs are watertight, but during a short swim had some water dripping in thru probably a leaky seam on the right hip) really make the difference during and also after the session. However the wind chill is considerable (was only wearing a real thin  fleece lined lycra underneath, next time try some more neoprene as a first layer) and my mouth seems to react a bit to the mouth piece rubber. But all in all, a valuable thing to have.
