Benjamin, I think you're right. Ultimately, after looking around and doing research on the Drillium, Quick-Fire, and Thru Hiker, I've decided that I need to be 100% satisfied for $250. So I'm going to return the size L.
Denis, thanks for the input.
Jeroen, glad the photos were helpful. I think you're right that it is a great jacket, it's just that sizing needs to be taken into account – especially for taller hikers.
So here's where I'm at: I need to know what constitutes full coverage in a rain jacket. Initially, I found the simplicity of the Thru Hiker very appealing because it allowed for (what I thought was) a long rain jacket that was still very light.
Are there any situations when a longer rain jacket would not be adventageous? Given that thejackets listed above are all sized very similarly, I'm unlikely to find one that provides a long fit. Even the XL Thru Hiker is only one inch longer than the L.
This being the case, I might get the Rab Bergen. It's about five onces heavier, but it'll actually fit properly. After all, an ultralight jacket that just dumps rain right in my crotch isn't so useful!
Alternatively, I've called Integral Designs and they're willing to alter an XL Thru HIker so that it's three or four inches longer (i.e. so that it fits like the photo they use to advertise it).
What do you guys think? How is full coverarge best defined? Are there situations when it would not be useful to have a longer jacket? In my case, might the Bergen be the way to go since, even though it's about 17 ounces, it will actually fit me?
