The Saga OG Logo Jacket is a pretty solid piece of outerwear as tested so far.
The design and style is excellent in Atomic Blue. The colors complement each other well, and it fits pretty much perfectly. The fit is tall for me (I am 5'9") and falls a few inches above the knee. It offers plenty of room to layer beneath while maintaining your ability to move freely. I have two minor gripes with the design though. The first is that I really feel that ski jackets need an inside pocket high on the chest for a cellphone or ipod. With just the hand warmer pockets down near the waste, your phone really weighs down and will swing excessively if you have the jacket unzipped, which can become a pretty big issue you you have a wire running up to your headphones/helmet. The other issue is that I worry the drawstrings on the hood and around the waste are going to end up lost inside the jacket.
The jacket is extremely lightweight, and by itself an excellent option as an only layer on a warmer day (40F+). Once it starts to cool down though you really need to layer under it pretty badly to stay warm. I found that a thermal base layer combined with one of the Saga riding hoodies kept me warm down to about 20F. Below that it starts to get a little hard to layer enough and still be able to stay comfortable. I had the jacket out in a 0F day, with two thermals and my Saga Riding hoodie and it just was not enough. This is a great jacket, but when it hits 0, you are probably going to need something that is insulated better.
As far as waterproofing goes, Saga has it rated at 5K waterproofing. My experiences so far are that as long as you are good about brushing the snow/sleet off yourself occasionally you will probably be alright. It will not hold up under rain like conditions though, I would guess that you will be soaked clear through in a matter of minutes in the rain. It does dry extremely quickly though.
It does not seem to be particularly breathable, I regularly find myself sweating in it, but that may be due to me layering incorrectly, and the fact that I tend to sweat alot.
I cannot speak to durability yet, I have spent 12 days out in it, and other than a few minor stains (due to the light color) it is holding up well. The construction seems to be top notch, and the material is great. I have however heard reports through the forums of the Saga logo cracking on the chest, but that is to be expected of anything that is screen-printed, especially when exposed to extreme temperature fluctuations. My only other concern about the durability (other than potentially losing the drawstrings around the hood and waist) is the zipper. It is a YYK zipper which is good, but I wish it was a larger size.
Overall I recommend the OG Logo Jacket by Saga to anyone looking for a stylish, lightweight jacket who is a fair weather skier.
Those looking for a single jacket to cover them in every set of conditions though will have to look elsewhere, as the lack of insulation and waterproofing will have you cold and wet on days the temps dip below 10F or during super wet snow/rain.
This is exactly what you need if you want to ski in a hoodie but can't because it's -30 and snowing out and you don't want to get frostbite on your nipples. Steezy as hell (I'm 5'8", 32 waist and got the L) without making you look a bean bag (read: tool). Enough room for my 750 fill down puffer and with 5k waterproofing it's perfect for almost any day out in Banff since any water freezes over in seconds there anyway. I have a Descente jacket I use for slushy/pow days, so make sure you have a backup plan for when you go real deep and it gets real wet (pun intended).
