First, I just got this jacket. I haven't worn it outdoors for more than a test run and can't comment on how effective it will be at specific temperatures. I'm writing this now since no one has posted a review on Zappos. I think this product deserves 5 stars in all categories.
I've had a Mighty Lite hooded jacket for several years and give it 5 stars also. For those of you who have that jacket, I want to share my experience with the 2 styles. I wasn't sure from the item descriptions that much is different except for the plush lining in the hood of this style. There's enough variation for me to keep this one. It's a bit heavier and feels warmer based on my 5-minute outdoor comparison, but it's not significantly bulkier. The plush hood is very comfy, and I'm hoping the added weight will keep it from blowing off in a breeze like the Mighty Lite hood does (neither hood has drawstrings, unfortunately).
The big difference for me is fit. I need a long jacket to keep me warm from neck to thigh while commuting. While the L in Mighty Lite fit better in standing position, it pulled across my hips when I was seated. I chose XL and it has been great, although when I'm walking it feels too large in the waist even with a light sweater. I ordered X and XL in this jacket to compare fit (thanks, Zappos). I am delighted that the L fits me well for all purposes. Plenty of hip room, while the more hourglass silhouette fits much better at the waist without being too snug. No problem for me with pulling across the shoulders or chest in the L. For reference, I typically wear size 10 Columbia
pants and M shirts. If you have broad shoulders, prefer a loose fit, or plan to wear bulky sweaters, you might want to start with the XL.
As for sleeve length, both X and XL in this jacket and Mighty Lite fall well below my wrists when my arms are by my sides. That turns out to give perfect coverage when I reach for the steering wheel or lift my arms. Both styles have inset thumbhole cuffs that felt binding at first but are a blessing for gripping cold steering wheels and dog leashes. If you add gloves, you can wear them over thumbholes to keep out wind or just treat the cuffs like regular cuffs.
This jacket also has an "extended" hemline. The scallop shape means more fabric to keep your backside warm when you sit down, which I appreciate. The Mighty Lite has a straight hemline.
Finally, my computer shows the Deep Rust color as brighter and more vibrant than the actual jacket color of both jackets I received. The jackets are what I would call a true "deep rust" that isn't boring and probably won't show dirt easily.
I am a Columbia devotee, so I can't compare their jackets to other brands. I do think the retail price point for all Columbia jackets I have is quite reasonable for what you'll get. I hope this review helps you decide and that you'll be pleased if you make this choice.
