We can't take the credit for the design of the Thunderbay, as it's a virtual stitch for stitch replica of an original 1930s jacket in our archives. In fact, the Thunderbay is a jacket that was worn by the founder of Aero Leathers for many years until it became too delicate for everyday wear, and thanks to some sterling work by David Macks, we have been able to identify the maker of the original jacket as Franco Canadian.

The Thunderbay jacket is exceptionally functional and ideal for protection from the very worst of weather - after all, the original stood up to decades of Scottish winters! There are two deep Moleskin lined hand warmer pockets, and the combination of the fur collar, heavy Horsehide, and Shearling lining keep the wearer snug and dry.

The fur collar, the adjustable belt, and the stud cuffs keep out any wind or cold that might otherwise get in. The Thunderbay leather jacket is one of the warmest jackets in the entire Aero range; there will be few jackets on the market that are better suited to the harsh Winter conditions.

While this shearling lined leather jacket is a 1930s inspired design, it is cut more like a 1950s style which offers a fit with quite a bit of room around the shoulders and chest, however it does taper down to a trimmer fit towards the hem.

We typically recommend ordering this lined leather jacket in your usual size. However, depending on your body shape, you may be able to size down for a more modern fitted look but this will need further discussion with our prodution team to ensure we can get the correct fit taking the taper and the sheepskin lining into account.
