Sizing is always tricky, sometimes companies change their sizing. However, I have a Haglofs Oz XLarge(predecessor of Ozo)and a Gram Comp Pull size Large and just tried them on. I am a slim 190 cm (about six four)and they both fit me. The Gram Comp Pull is a bit on the tight side, but then the cut on both smocks is fairly slim. The reason for both working is probably that they have very generous sleeve lenghts, which seems typical for Haglofs. I have their windshirt Gram Shield which is the best-fitting windshirt with the best hood I have ever owned,also with long sleeves.
Both the Oz and the Gram Comp have worked well for me. The Gram Comp was a pre-production sample and had a faulty chest pocket that came unglued. The Oz is probably my all-time favorite rain shell but a bit to worn these days. In fact I used it the first time on the BPL Trekker III course in 2007, it can still be seen on a photo (green to the left) where Don Wilson, Mike Clelland and myself are huddled over a map in the biting Beartooth wind.
