Have to agree on the size and the previous speaker had the article also ordered as a precaution in 54 and 52. Both versions seem to be the same length of about 66 - 67cm to possess. Only in the width / sleeve length is Gr. 52 a bit narrow / kept shorter, which also act here almost identical. In general, the jacket is rather slightly wider cut and not slim fit / Fitted as I would have expected from the photos here. Beyond the 185cm height, this should then be probably too short in 52/54. Who is more muscular built or stämmisch and a short not to limp engined Look preferred will be but certainly satisfied. Also use as a mid-layer, for example, under a soft shell offers itself because of the short fit. Only the collar is a little tight advised for thicker neck circumferences in the completely closed state, due to the high elasticity of wool but still in the frame. This comes with plenty 9cm then directly to the chin and is therefore ideal for me. Quality and comfort thanks to Merino very good. The fabric is thin but a fine mesh woven and opaque enough for my needs. Even for a light sweater quite robust YKK zippers are positively highlighted. Conclusion: Very nice summer / transition jacket, as well as a middle layer for colder days recommended.
