My review should help you choose.
Special Size Type: Standard, Size: Small, Color: (New) Black Coffee (Non Stretch)
Honest review. Levis quality, the color "coffee" is actually a real dark brown and is not denim, is corduroy. The Dark Brown looks like an "olive brown" color. The "standard" fit feels perfect width on the torso but too long, with slight long sleeves. The "Original" fit feels the same as the standard fit but slightly smaller. The "relax" fit has perfect length sleeves (on the shorter side), comfortable torso width for layering, but way too long. Hope this helps you choose.

Perfect! Read this for large size
Special Size Type: Standard, Size: Large, Color: (New) Rinse
Man, let me tell you when I say I've never been so nervous about an amazon order before. I've wanted one of these for a long time but the reviews had me a little shook. I'm 6' tall and 210lbs. I'm definitely not fat but I do have a bit of a beer belly, the rest of me is pretty lean and muscular. I measured my chest at 44" while wearing a light hoodie. The size chart said I should be a large and so that's what I ordered. It fits perfectly, I can honestly say an XL would probably be too big. The large is not too tight, not too loose. I have plenty of room in my shoulders, and I can wear a flannel shirt and hoodie under it and button it closed comfortably. The arms are the perfect length for me as well, falling just past the wrist. I read a few reviews about the quality of the denim, I got the rinse color (dark wash) and it feels plenty high quality to me. No issues that I can see with the pockets, buttons, or stitching anywhere. I did however get a blank red tag on the front pocket which concerned me, I looked that up and apparently Levi manufacturers 10% of their products with blank red tags instead of saying "Levi" and supposedly that makes them more valuable because of the rarity? Whatever, I don't care about that as long as it's not a knockoff. I plan to wear this for a long time so the resell value is of little importance to me anyways. Even if it was a knockoff, I'd probably keep it anyways because of how good it looks. Overall I'm pretty happy with this purchase and would recommend.

“This Jacket Changed My Life, My Posture, and Possibly My Destiny.”
Special Size Type: Standard, Size: X-Large, Color: Colusa/Stretch
“This Jacket Changed My Life, My Posture, and Possibly My Destiny.” I bought this Levi’s Men’s Trucker Jacket on Black Friday for 50% off, and honestly, I think the universe has been waiting for this moment. The second I slipped it on, I felt the air shift — like somewhere, a tumbleweed rolled across a Walmart parking lot in respect. This jacket didn’t just fit. It claimed me. Suddenly, I walked differently. Not better — just with more narrative significance. Like I was the mysterious side character in a Netflix show who only appears to give life-changing advice next to a jukebox. People look at me now like I’ve been to places. Seen things. Done questionable but noble acts on the open road. What This Jacket Made Me Believe About Myself: That I could fix a motorcycle using only pliers and emotional willpower That I should own sunglasses even indoors That I absolutely should lean against things while staring into the distance That I have opinions about blues music That someone, somewhere, owes me money My confidence skyrocketed. My responsibilities? Stayed exactly the same — but I now ignore them with swagger. The Black Friday Factor Getting it 50% off activated a new primal ego inside me. Every time someone compliments it, I immediately shout: “THANKS — GOT IT HALF OFF!” Even when they weren’t complimenting it. Even when they weren’t talking to me. Even when I was alone. Durability This thing could survive: A bar fight A mild tornado Being run over by a shopping cart stampede The emotional collapse of a man who just realized he peaked in high school It’s rugged. It’s iconic. It smells faintly of “I could do better, but I won’t.” Side Effects (documented): Strangers nod at me Kids think I know how to play guitar I feel obligated to say things like “Let’s ride” even when entering a minivan My reflection winked at me once Final Verdict This isn’t just a jacket. It’s a lifestyle upgrade. A fabric-based personality transplant. A denim prophecy fulfilled. Five stars. If Levi’s ever discontinues this jacket, I will chain myself to their headquarters and demand justice.

Vintage 60's cool, but sizing is a difficult decision
I can't believe I haven't owned one of these for the last 40 years or so. To put one on after all these years takes one right back to the questionable days of one's youth when you wore these bare chested underneath while tooling around on your Kawasaki 500 triple. Well it will take you back if you haven't let yourself go too far! I received both a large and a medium in black (love the free returns on clothing, I always order two sizes so I get the right fit). They are both made in Mexico and look very neat and well made, the denim is on the thin side but OK for warm weather. Nowhere is there any tag saying shrink to fit or shrinks two sizes. The tag says machine wash cold, tumble dry medium. The large is quite large on me (I'm 5'9" 168 lbs trim and athletic build, more often than not I wear large in T shirts and jackets), the sleeves are way too long and loose, body too long and loose. Would have to shrink drastically to fit me, I really doubt it would shrink anywhere near that much. This type jacket is just all wrong if it's too loose fitting, witness the BLACK color one in the model photos, just not too cool. The medium fits much much smaller but IMHO perfect for this style jacket, a classic fit like Steve McQueen or Robert Plant would have sported, high waist and tight shoulders with sleeves rolled back a little. If you look at the model in the 'HARRINGTON' color you have the idea. It will be totally bitchen on today's big black BMW oilhead. This is the youthful fit I was looking for but any shrinkage would be too much. I am conflicted because I would like to wash this jacket and break it in, put a little wear and tear on it. But I wouldn't dare dry it with heat. I might try washing it in cold water and then line dry or I may just dry clean it. I am tempted to go out and drag it up and down the gravel driveway and run it over with my truck a few times till it acquires some of the same attitude it inspires in me. All I need now is a Psychedelic soundtrack and I'm all set to relive the glory days, better than the first time around. A little research on the Levi's website reveals they have a regular fit and a slim fit in addition to this relaxed fit which is the only one available on Amazon. I find that this relaxed version works well in the medium size anyway, it seems to be relaxed only in the body, not so much in shoulders or sleeves.
