I'd wear it without the breast patches AND as long as there was an Ent patch on one of the sleeves.
It appears the sleeves will have the Starfleet patch and the NX-01 patch, according to the description. But I agree, while the excess patches may be appropriate to a "flight jacket", it takes away from the overall look.
Quite frankly, I would've jumped at this if the front patches were optional. In fact, without and patches may even be better.
Star Trek merchandise doesn't need to scream "STAR TREK!!!". Subtlety is good. Fans would recognize the jacket design, and others would just wonder what the gold lines on the shoulders are about on this dork's jacket...
