Motorcycle Jacket.
Zip-vent slits on the front of each shoulder, same for the inner side of each of riders arms, ideal for coolness going forward. Closure of jacket at the front by means of zip and velcro. Zips at arm ends near wrists, press-stud buttons on garments sides and on garments arms useful for taking in-letting out a bit of clothing slack, velcro (Halvarssons branded) straps for adjusting the length of the garments waist.
Finally of course protection to the areas of each shoulder and each elbow.
Good quality and moderately used Jacket by Swedish makers Halvarssons. Says 52 size but that's Euro, equivalent to about 42 for UK. It's a tourer jacket so will be a bit baggier than sleek fit race garment.
Please note, the riders front pockets have a border, and in the riders right one the edge is joined to the jacket material as it should be, but (picture 15) the left side one has some "curling up" condition. Despite that everything is still firm and intact, thank you.
