KermudjinI communicated with helitemoto.com about the sizing issue. Although I typically wear a large in US sizing, after taking measurements as directed in the RevZilla page about sizing, it looked like I would need a 2XL to accommodate my middle aged girth. The rep assured me an XL would be the right size. He also hinted that the helitemoto website would have a 4 hr Black Friday sale tomorrow, suggesting I wait on the purchase until then.
Edit: looking at helitemoto.com at the moment, the only thing on their Black Friday sale is the turtle vest at $599. That is $100 more than the drop last week, as I recall.
KermudjinOk, it turns out heliteMoto.com has a four hour sale on Black Friday from noon to 4 with this jacket marked down to $499 + 22 shipping. Act fast if you want this amazing deal. You have to put the item in your cart and proceed to checkout for the reduced price to appear.
