I recently bought a B3 from Second Street. The size is 40. I've bought and sold Avirex B3s many times before. Anyone who knows, knows, haha. The reason I get rid of them is because they're heavy and difficult to put on and take off. This one is a no-brand, but it's made of natural sheepskin and shearling. The shearling is probably crushed or cut to about half its original length. It's just as warm, but it's lighter, easier to put on and take off, and easier to wear. However, the belts and connecting leather are not genuine leather, but some other material. It's durable, but the lower belt in particular shows discoloration. The leather on the arms is probably the original color of the sheepskin, but as you can see in the photo, there's some color unevenness on the left arm. It's easy to wear, and the leather is in very good condition without any damage, but it has these issues. As for the size, it feels slightly roomy on me, who is 176 cm tall and weighs 75 kg. I recommend it to those who don't care about the brand or the fine details and want to wear it roughly.
