I'm not sure who the marketing genius is that thinks Tall sizes means Big & Tall. The few major jacket manufacturers figure at a tall size that they may as well build the coat big enough for two people. Granted, there are some in the market looking for this size, I'm just not one of them. I'm willing to pay for the extra material needed to make the tall size but don't feel like I am getting my money's worth when I have to buy more clothes to minimize the draft that keeps getting in under the tent. And sleeves? These little thumb skirts to cover the wrists are not exactly what I had in mind.
Screen or mesh in the vent openings. I have seen Klim gear where the coat and bibs were gaping open so they could cool down. Does the warranty cover damage from the garment getting caught on something and stressing things that weren't designed to be stress points?
Color options that don't look like pre-school pj's.
Overall, the market is forcing some drastic improvements in the garments from all manufacturers.
