Columbia keeps changing the names and styles of their "Titanium" line, so you may need to check and compare the features I talk about here. I guess this is more of a review of the features and the company than of this particular product.

I would have preferred to get a mil-spec gore-tex parka for hiking, but they are insanely expensive for my 2XL frame. Of the major brands, only Columbia makes one large enough for me. I suppose the market research of companies like Sierra Designs and The North Face shows that only scrawny guys go hiking. Columbia to the rescue!

As for the jacket, it's a bit flimsy for my taste, but I like bullet-proof designs. Nevertheless, it's held up well for me over the years. I only have one small tear in the shell, having put a hundred trail miles on the thing. The omni-tech waterproof/breathable layer seems to do its job, but be aware that the sleeves will get plenty wet in a downpour. I guess the breathable fabric is too expensive to use everywhere. This seems to be the normal construction, though, so it's not like another manufacturer will have more square inches of gore-tex.

The waterproofing works well for anything less than a downpour. I do tend to sweat quite a bit when heading uphill, and the 'breathable' aspect of the jacket doesn't work that well for me. Heck, if I'd hike with no top at all, I'd still be soaked in sweat! I suppose that this feature works as well as the other shells I've tried, if not better. There are an adequate number of vents and zippers to keep the air flowing.

I've been talking mostly about the shell, but this is a two piece system, with an outer shell and an inner lining, which doubles as its own fleece. I actually wear the fleece a lot more than the shell, since it's not only fashionable, it's quite functional. I even singed the front of mine after a white gas explosion, but it still works well and looks great, although it feels a bit weird where some of the fleece melted :-)

The things I like the most about this pair are the numerous zippers, but they are also the things I dislike the most. While it's nice to have a full-length zipper on the sleeves, as well as front pocket vents, the zippers themselves get stuck quite often. I have had to stop and unjam the zippers about  a third of the time I open or close them. This is annoying. Still, that's better than having to stop, take off my pack and remove a layer. I've also found that keeping the sleeve taught helps quite a bit.

The sleeves have all sorts of ways to keep warm air inside, too, including velcro clasps around the sleeves, a 'powder skirt' to keep air and snow off of your belly, and elastic drawstrings around the waist, hood and mid-section. The hood also has a nice little 'minibrim' to keep water out of your eyes in the rain.

The useful temperature range of this system is impressive. I've used it year-round in Pennsylvania, and we get some cold winters. With ski goggles and the hood drawn tight, I've hiked in near-blizzard conditions with heavy snow and air temps in the 20s. I've also used this in summer thunderstorms and in the spring. When the air temperature is unpredictable, this system has never let me down--it even has a bunch of pockets to carry accessories. I use a zippered pocket on the chest for my cell phone and car keys, and there are roomier pockets around the waist that are good for goggles, hats and snacks.

So to summarize:

Strengths:
Air tight, warm
Breathable, for the most part
Comfy fleece
Lots of vents and zippers, full length on the sleeves
Lots of pockets
Wide temperature range
Drawstrings, powder skirt and cinches on the sleeves.

Weaknesses:
Zippers get stuck
Breathability fails in extreme sweat conditions (but what system doesn't?)
