I have been riding for just about 20 years, including a few years of racing AFM in california, plenty of mid-distance touring, and commuting about 150 days a year (plus weekend fun riding, although never as much as I'd like). My gear gets a workout!

Shortly after I started riding I felt like I had not picked the best street riding jacket so I did my research and tried on a bunch of jackets (good selection here in NorCal) and decided on the Spidi NT, a good looking and very well built 3.5 season textile jacket. That jacket lasted over 15 years of riding, albeit with some breaks in-between (took breaks after marriage, kids). It never actually died on me, but after 15 years it wouldn't get totally clean in the wash and some of the liner and armor bits were disintegrating slowly on me. I felt totally safe, but it was time for a refresh.

So, on to find a new jacket. As usual, I did my homework, reading about everything out there that would be 3-4 season (still in NorCal, so 3-4 seasons here might be 2-3 seasons in Alaska or Michigan), highly protective, and look great. I tried on about a dozen jackets in this realm in local stores. And if I had found "the one", I would have bought it - but I didn't find the perfect jacket as they were all compromised in one way or another.

I could not find a Spidi to try out live b/c they have not been in the US for a few years and they are just coming back, with a very weak to non-existant showroom presence. That said, I have used RevZilla before and I saw this jacket and knew I needed to try it. So, with the return policy in mind, I took a flyer and bought it.

I'm 5'11" and 185, reasonably muscular build (32-33" waist in jeans depending on the prior day's gluttony). The large was a bit snug. However, it was an amazingly promising jacket so I returned that and got an XL. That fit wonderfully. So, on to the details...

First, let me say that I really care about quality, and I have always been willing to pay a bit more for something that will last me a long time and give me great service. This jacket positively reeks of quality. No loose threads, no ill-sown pockets, and amazing detail. My wife was a buyer for Nordstrom for years and owned her own high-end women's boutiques, and even she was blown away by the level of detail and thoughtfulness.

This thing is 3 fully-finished jackets in one. The warm liner can be worn separately and I have done so. It fits great, looks great, despite having a few buttons and clip-in points that you typically wouldn't see in a stand-alone jacket. Doesn't matter, it looks great and pops in and out in a jiffy. I'm using that daily on my commute now that fall is truly here.

The rain liner is of higher quality than most rain/wind breakers I have seen at REI. Like the warm liner, you can wear the rain liner on its own and it's a great layer. Also pops in and out quickly and easily, with the warm liner sitting inside it if you want that warmth, or not, if you don't.

Finally, the outer shell is a thing of beauty. The lines are sleek and definitely "european". Easily passes the wife acceptance test. However, if you have a spare half keg in your gut, I don't know how you'll fit in this thing. There are adjustments aplenty with side straps and arm straps and velcro, but it's only so wide. Works like a charm for me, but YMMV.

All of the zippers and buttons are high quality and beautifully attached. The thing is so well finished that you are not faced with a bunch of ragged stitching. Everything is tight and just so.

I'm using this as my daily commuting jacket, so far about 50/50 with no liners or with the warm liner (the rains haven't hit yet., but soon). It's just so sweet. The jacket is very comfortable on the bike. It's not too short, but short enough that it doesn't bunch up against the tank, and I am riding a 2006 GSXR 1000, so I'm definitely hunched over a ways. The arms to waist length ratio is just right for me, whereas some jackets are too upright and some are too sprawled over, requiring unusually long arms to work right. When zipped up and locked down this thing is very wind-proof and warm (have only ridden down to the high 40's at this point) with only the outer shell and warm liner. I'm sure it's warmer still with the rain layer, but I have yet to need that on the road.

I feel very well protected. The armor is in the right places and is the right thickness. I have a "turtle" back protector from Helimot (the best one made IMHO) which puts most back pro to shame, and that thing slid right in to the back protector slot in this jacket and fits like a glove. It's a bit thicker (happily) than most back protectors but the jacket's fit flexibility easily accommodated it.

Over all, although I only have a couple of weeks and a few hundred miles on the jacket, I'm very satisfied and am looking forward to another very long stint with another great Spidi jacket.

I bought this jacket while living in Europe this summer and finally got it out for a fall ride ride. 600 miles in 2 days.
Rain - no issues. Wind - no sneaking up into the jacket.
I am not the warmest person in the world but wearing a Merino wool T-shirt I needed electric heat (in the wind and rain) below 50F.
The next sunny day I added UA thermal LS undershirt and still needed heat up to 50F.
I could survive down to low 40's but not more than an hour or 2.
I normally wear Med to Large and this is snug as a large without the back protector. Room is there for my warmnsafe liner.
I'm 5'10" and 175 lbs.

I've been wearing Spidi since 2002, as always good fabric and contruction. Really like how the high Pads quality suit great my elbows and shoulders and also make me feel protected.

Only con is that Back Pad is sold separately.

I am suspect... I am unconditional fan from SPIDI, I use SPIDI since 1997. I had 2 different models since then, the last was Ergo 05, That was heavy and hot (but good). This 4Season has all the features I expect from a Jacket, now in February 2017, temperatures ranging from 32F to 70F, rain, wind.
The jacket is perfect.

After spending about $1k on this combo im left alittle dissapointed. First of all had to buy an additional back protector because the jacket has none. Second is the lower front portion of the jacket constantly folds up while riding. Theres a little elastic string to tighten everything up but its pretty useless, ill have to get it modified somehow so it doesn't do that because its unbearable, especially in cold days or rain. Besides that it looks amazing, airflow is decent because of large vents. The pants melted like butter the second they made contact with the exhaust and the jacket seems made of same material so have to watch out for that. I usually wear an L, but this had to be bought in XXL for a slim feeling fit. 6.2", 197lb

To note, I did not get to ride in this jacket. It seemed to be of good quality. Unfortunately, both large and xl were too small for me. Definitely not American cut. I'm
6' 175, fairly athletic with broad shoulders. I've been having a hell of a time trying to find something that fits via online shopping. Another thing I didn't care for are the 3 separate zippers to operate. Hastle if you're using all the liners. Other than that, pretty rad lookin jacket with tons of versatility. . Love the hi viz on this model. I suppose this is svelte cut? I'm not svelte. Not at all. I'm just A giant American barbarian.
