Customer Reviews
Overall rating: 4.8 / 5 from 30 reviews.
I’ve had mine for 3 weeks and love the feel and fit! Perfect for the cooler days. Noble Threads has been very accommodating, open and honest. Thank you
I work in a clinical setting so I have been looking for a comfortable blazer that was modern/professional/comfortable. And this blazer checked all the boxes. Immediately when I opened the package and saw the coat, I knew I would love it! It was initially a little long for me for my height but because the label mentioned an about 4% shrinkage if you dry the coat in the dryer, which you can avoid by hang drying, I washed it and dried it in the dryer and it fit me perfectly. The first day I wore it in clinic, I received a compliment from a patient asking me where I got it as he had been looking for something like it! Will definitely be getting the lighter version of this coat.

Looks great Brandon! Thanks for sharing!
Great casual blazer! Comfortable fabric that doesn’t wrinkle easily, great color. I have already received multiple compliments on it. I do wish the overall length were 1-2” shorter to make it more consistent with a casual profile, but certainly not a deal breaker by any means. I will be getting the charcoal blazer next!
Love NT's products and picked these up during early access. Just got them, and they've instantly became my favorite go-to's for all my Zoom meetings. Super unique casual style and great for when I don't want a super formal blazer.
Got both colors! Fits great, super comfortable, and I like that oatmeal contrasts well with dark colors and the black blazer contrasts with light colors. Huge fan.
Just got mine and I LOVE IT. Super casual, comfortable, and exactly what I was looking for! I'd say it's more of a slim fit. I love that it feels more like a cardigan or sweatshirt from a comfort level, but looks really nice as a standalone with a t-shirt or polo as well as my button downs. I wasn't expecting the subtle herringbone texture, and I think it's a huge plus. Also, since it's more of an off-black, it still looks nice with true-black undershirts and has a nice contrast.
The blazer fits well on my son’s athletic build. He’s 5’11” 210lbs. He loves the blazer, it fits quite well and the fabric is very comfortable. A stylish design that goes easily from work to a casual evening out!
The item fit very well except for the arm length. You should offer Long, Regular and Short options. I have a unique body where my size is Large but my arm lenght is Short. After my purchase you sent a discount for alterations. I appreciate the gesture but I did not apprecitate that it came after purchase, because it delays being able to where it by having to send it back and waiting to receive it again.
Amazing product and high quality items.
The first shipment was the incorrect size, but the company is so intuitive that the leadership team responded to my concern and sent the correct size with overnight delivery.
Fantastic products and even better team!
I actually LOVE the blazer, but I have a longer torso and short legs so I wish it could come in a slightly shorter version as it is just a tad long. If I had longer legs it would be perfect! Some of the other brands I've gotten have the same blazer sizes in Regular and Short and I usually get short. I am keeping it as I do really like it and can make it work, just my feedback on it.
Store owner replied:
Hey Josh thanks for keeping it real! This is great validation. I've actually just greenlit a .5inch reduction in height across all sizes. It's a subtle cheat in the right direction IMO. Gen 2 will have these changes, which is probably 4 months from now. Also, we do a tailoring program and do a small refund on tailoring if you want to have a pro bring up the blazer. Always an option. Appreciate you trying to make us better.
Tight on my forearms. which is unusual. Everywhere else perfect.

Operational Questions
What happens if I don't like it, want to swap out, or it doesn't fit?
Free returns and exchanges for 45 days from the day your order ships. Start it in the returns portal, print the QR code, done. We cover the shipping on your first exchange. Items that come back needing care before resale get a flat $20 restoration fee.
Can I return sale or "last call" items?
No. Sale and last-call items are final sale and cannot be returned or exchanged, which is why they are priced the way they are. Check the size guide before you buy; legacy products run one size small.
When will you ship my order?
Orders ship within 2 business days from our warehouse in Michigan. Orders over $150 get complimentary shipping, which takes 2 to 5 days depending on where you live.
What if my package is lost or stolen on the way?
We offer package protection through Route, which is package insurance protection. 0% of that fee is taken by Noble Threads. It's a pass-through of protection. With wildly rising package theft, we think this is the right move and we recommend it.
If you do not opt into the protection, you can open a claim with USPS/UPS and they'll eventually give you a refund (though it's pretty slow).
If it's our fault, and not the shipping provider, we'll cover it no questions asked. We record all of our shipments for quality assurance.
Noble Questions
What's included in your free shipping perk?
We offer insured USPS priority shipping for orders over $150, which arrives within 2-5 days.
Do you have a referral or loyalty program?
Yes! We have a "20 for 20" model, where you can give a customer 20% off their order and you'll get a $20 credit towards your next order. This appears after your purchase and when you review our products.
For loyalty, we're currently working on it, but want to provide more and more perks (like discounts and stylist perks) for VIP customers.
Where is the team based? Where are these manufactured?
Noble Threads is an American company based out of Austin, Texas. Our luxury cottons are sourced from the United States and Peru, and every order ships from our warehouse in Michigan.
Do you offer a first-order discount?
Yes. Subscribe to the newsletter and 15% off your first order lands in your inbox right away. It is also where new releases show up first.
