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.
