Buckle & Seam Sierra Messenger Bag Review

The Buckle & Seam Messenger Bag – Sierra 15″ is a leather messenger bag for business use and accommodates 15″ laptops ,as we know the business bag  is more drab , but  the Buckle & Seam Messenger Bag Business Bags shouldn’t be boring anymore, tbecuase of  Buckle & Seam ombine classic designs with the linings and monograme , we will check the bag today


The Buckle & Seam Messenger Bag – Sierra 15″ is a leather messenger bag for business use and accommodates 15″ laptops. You can put the iPad and  magzine , book  in the padded laptop compartment. The Cara Leather Satchel can also fit a notebook and document folder. A separate pen slot will help you stay organized & the phone pocket fits your smartphone or power bank.

There is also a 13″ version without a handle – Cara 13″). The bag is made using full grain leather (their website states that the bag is made with the entire grain which all layers of the leather have been kept and worked together.

Package contents:

I was so excited when I received the  package . The Buckle & Seam Messenger Bag – Sierra 15″ came in a navy blue non-woven polypropylene material bag (or poly non-woven which is the same material used in reusable grocery bags)  ,it is look nice and more texture for the package .With a  printed materials about the leather and leather care also look nice. The cards were actually printed in German, so I had to use Google Translate to help me understand the information.


The leather has been vegetable tanned which is more environmentally friendly than Chrome VI tanning or other chemical tanning processes .Carefully selected 1.5 to 2mm thick premium cow leather. someone called  the leather Crazy Horse Full Grain Leather.Vegetable tanning process to avoid the use of highly polluting chemicals usually used with chrome tanned leather.



The color is true,  it is the same as with the site .  the color seem very brown – no red at all as depicted in the photo above on the right. maybe the reason of light, so the picture will be a little  difference.



The front of the bag shows how the bag is assembled with a double stitch using recycled polyester thread. The main compartment flap uses a tuck catch lock closure.


According to Buckle & Seam’s Managing Director, Marco Feelisch said  that  eveloped by our in-house design team and [is] manufactured only for us out of premium cotton, so the bag used the blue custom lining of the bag. The lining of bag look comfortable and it will be suit for the  leather color.


The bag comes with a key to lock the tuck catch lock closure. When the bag was shipped to me, the key and the Buckle & Seam tag were tied to the bag through one of the pen/pencil slots using a strip of leather as shown above.

A close-up view of the tuck catch lock closure used , I’m not sure what kind of metal the bag uses in order to determine if the hardware will endure years of use.




The key is very small and thickness. maybe it will be lose easy, but there is  ring hole, we can used a  rose theough it, then put the bag . if lose the key , maybe we  can not open the  bag .However, the locking mechanism is not complicated. The two prongs on the key insert into the lock and when turned in a clockwise direction lock the bag such that the button can no longer be pressed to release the closure. It easy to open the bag, but just be  care about the key . Dont misst it .


The D-rings are used to attach the leather shoulder strap to the bag.D-rings are attached to the bag using stitching and two metal rivets. so you can used the leather shoulder strap , if you dont like  the shoulder stap ,  you can give it up, there is a handle that you can use.You’ll also notice that all edges of leather have been sewn and sewn ,I’m a bit like seeing the raw or polished edges of my leather products, which also helps me see the quality of the leather used.

The back of the bag also shows the stitch and another zipper pocket. YKK elastic zipper for buckle and seams of the business package, according to Mr. Freelisch


There is a trolley strap so that you can slide the messenger bag over a suitcase handle to make traveling easier .


The trolley belt is attached to the bag with elastic fabric and can be stuffed into the pocket until it needs to be used again. I wonder if the elastic fabric will move over time.


The bottom and sides of the Sierra messenger bag are made from three pieces of leather.



They use leather with an average thickness of 1. 8 to 2mm. However, the bag handle is one of these areas, with two layers of thin leather stitched together to make the handle about 2 mm thick.


The leather shoulder strap is adjustable by using the metal buckle.



The straps made togher with three thin layers, but I also notice the shoulde strap can get the length they want, the straps are also stitched together. The weld seen above also exists on the other side of the same point. Again, the straps are high stress areas of the bag and are therefore more likely to fail in the future due to the design of the straps. if the strap were made entirely from one or two thick layers of leather without splicing.


The main compartment of the bag is completely lined with a cotton lining. There is a laptop pocket in this compartment. The material separating the laptop from the main compartment is sewn to the inside of the bag with two 2″ wide strips of elastic material (top and bottom) on both sides so that the bag can be stretched to accommodate a thicker laptop. The top of the laptop pocket uses a Round magnetic seal (approximately 2 cm in diameter).

The main compartment’s internal measurements are about 14″ wide x 3″ deep x 11.5″ high.


The thin zippered pocket shown above has internal measurements that about 11.25″ wide x 9.75″ high.

The front pocket measures 14.75″ wide x 8.5″ high internally.


I found that it could comfortably carry a 1″ binder and a couple of thin paper folders as well as a pencil case.


The pens fit snugly and were a bit difficult to retrieve as was my phone. My phone measures 6.25″ tall x 3.25″ wide x 0.375″ deep.So you can check themeasures of the  phone .However, when the bag is full, the photo above shows how much pressure on the handle when carrying it (I don’t even have a laptop in the bag). The leather stitched and riveted handles here is not very thick, but below the handle attachment, there is a 7″ long x 0.5″ wide strip of rigid reinforcing material hidden beneath the main compartment flap behind the bag liner.

Overall,The Sierra messenger bag was easy for me to carry using the shoulder strap,and the  leather is vegetable tanned which is more environmentally friendly than other chemical tanning processes, that is will be more great and look fashion ,it is not a boring business bag at all.
