I also posted some comments on it last week, since I'd seen the 2012 version in Tokyo.
"I was in Tokyo last week and bought a few things at Mont-Bell, mostly bike stuff for the upcoming Austral winter. While I was in their Ebisu store I spotted the 2012 Versalite jacket. I presume that this is the version which David Chenault reviewed in March but the claimed weights appear to be different (this one is lighter - the current US model works out at a claimed 189.90 grams for a size M (cf 209.8 grams claimed/198.4 grams actual for the US version in David's article)) so maybe it's a later iteration?
The Japanese market jacket is claimed to weigh an average 168 grams (the 21 grams weight difference between the 2012 Japanese and US versions is presumably due to the pit zips which the Japanese market jackets don't get). Instead of nominating a weight for a particular size they nominated an average for the range of sizes available. Since there are 5 sizes and the middle one is M, that's presumably the weight of the medium. That's very light for a jacket with the waterproofness and breathability they claim (20,000/20,000 - the details are on MB's US website if you're interested). The question then is what is the variance between the sizes? Can the L or XL be under 200 grams?
Impressions? The jacket looks and feels like a windshirt (actually the blue is very similar in colour to the blue Houdini) but with a clear plastic coating on the inside: that and a slight stiffness are the only indications that it's not just a windshirt.
In terms of sizing I was able to comfortably wear both the L and the XL (I'd probably be a US L as a comparison). The length was below the waist and cut longer at the back (so the low weight is not simply because they've cut the jacket really short) but it's still shorter than my Montane LiteSpeed.
One thing I did really like was that the cuffs had velcro and elastic, which I think should be standard but annoyingly isn't. In fact a Mont-Bell softshell I bought didn't have the elastic, which is a pain.
My interest in the jacket was because I'm always looking for a super-light breathable waterproof that I can carry in my panniers in case of rain (I commute by bike most days). The price in Japan is pretty reasonable but I decided to not buy it until I had checked some reviews about its breathability. (I was also thinking that it's Breeze Dry-Tec, which gets good reviews, but it's actually Super Hydro-Breeze which, based on David's review, doesn't seem in practice to match eVent or Breeze Dry-Tec). On that basis, for me, the light weight alone would not be enough to justify the purchase, as in my experience cycling tends to steam up even eVent unless it's very cold."
