GRAMS28 is such a "Just the right amount of high end." aimed at
Minimalist & luxurious bags & accessories brand
founderThere is no bag that can simultaneously satisfy both the texture and practicality of luxury."
The brand was started from the desire of the founder, a designer.
It is precisely this compatibility that makes me a loyal user.
Origin of the brand name
The name is derived from the movie "21 Grams," which was inspired by the weight of the soul (21 g) and the number 28, which is the sum of "every day = 7 days.
"A product with soul, a useful companion seven days a week."This is the idea behind the project.
Why we can offer the finest leather at a reasonable price
Sourced directly from famous Italian tanneries
Highest gradeFull grain."What is
About Leather Grades

- Split leather
GRAMS28 chooses "full grain",The highest grade of leather with fibers packed down to the "core" of the leather.The following is a list of the most common problems with the "C" in the "C" column.
This is why even thinly finished products do not easily lose their shape, and can be aged for up to 10 years.

The appeal of this product is its thoroughness in selecting the best leather for each application and unifying all leathers with full-grain.

In other words, this code is

171 Laptop Slingis, as the name suggests, a cross-body sling bag specialized for carrying a notebook PC.
This model follows the design of GRAMS28's very popular "154 City Pack," but with a larger capacity.
It stands out for its minimalist x luxurious presence and can be used in a wide range of situations from business to casual.
Features & Functions
It is a highly functional sling bag that embodies what 14-inch notebook PC users "wanted.
The most distinctive feature is the built-in independent sleeve for notebook computers.
The main compartment has a thickly padded laptop sleeve that just fits a 14" MacBook Pro.
A hook-and-loop fastener clasp secures the PC in place, allowing it to be safely and directly stored without the need for a separate case.
The cushioning is high, so there is no problem getting in.
The well-developed storage pockets are also not to be overlooked. Inside the main compartment, in addition to an open pocket for relatively large items such as a smartphone and charger, there are two mesh pockets on both sides for organizing small items.
It is designed to hold cables, pens, mobile batteries, folding knives, and other EDC tools, and has a "pocket within a pocket" design.
One outside zippered pocket on the front (ideal for a thin notebook or passport)
There is also a strap that can be threaded through the handle of a suitcase.
one's feeling when using something
At first glance, the garment felt highly comfortable to wear and conformed to the body in a way that could not be imagined from this front view of the size.
One of the reasons for this is still full-grain pebbled leather.
It is characterized by a good degree of flexibility while maintaining a clean silhouette.
The uneven grain is also resistant to scratches and water, a reassuring feature for everyday use.
The gusset is made narrower for easy everyday use, while still accommodating a PC, so that it can be easily snuggled up to the body.
Although slim, it still holds a full-size mirrorless camera and a telephoto bazooka lens with room to spare.
There is no handle on the top, but it can be used as a sub-bag for camera and equipment.
The pockets are quite substantial, so you don't need a pouch for small gadgets.
You can carry them while keeping them neatly organized.
Word of mouth and reputation
Reviews
- It has room for a 14-inch MacBook Pro, an iPad, and headphones. It looks slim, but it holds more than I imagined."
- The leather texture and stitching are perfect. I always get compliments when I unfold it in a cafe."
- The bag follows my body perfectly and doesn't sway when I ride my bicycle. I don't even mind the weight.

GRAMS28 157 Essential Sling｜Minimal Sling for EDC
Specifications & Appearance
157 Essential Slingis a compact sling bag designed to carry everyday essentials in style.
This mini yet functional model can hold a compact digital camera in addition to a minimal EDC such as a smartphone, wallet, and keys, and is one of the best-selling GRAMS28 products.
The crossbody has an urban, modern look and is light enough to be carried easily.
Features & Functions
As the name "Essential" suggests, this sling bag specializes in smartly storing the bare essentials.
In terms of storage, the bag is notable for its surprisingly high capacity despite its small size. Inside the main compartment are two zippered pockets and a pen holder, allowing you to organize even the smallest of items.
It can hold a small camera (Ricoh GR III or Sony ZV-1 class) or even a Nintendo Switch Lite if needed, making it more versatile than it looks.
The metal buckle is engraved with "GRAMS28" and the model number, giving it a military and industrial look.
The buckle is not only a design accent, but is also functional, with a quick-release mechanism that allows the bag to be attached and detached with a single touch. The bag can be attached without putting the bag over the head, eliminating the stress of putting on and taking off the bag.
one's feeling when using something
It is just the right size to hold everything from essential EDC items to mobile batteries.
I like this minimal size very much.
The 157 Essential Sling is designed with straps that connect to the top of the bag on one side and to the side of the bag on the other, so that the pouch stands perpendicular to the body when worn.
The left shoulder strap is fixed, but it is flat, stable, and comfortable, with almost no blurring when walking.
The high quality is of course attractive, but it is this kind of practicality that makes it possible to trust and use the product on a daily basis.
Word of mouth and reputation
Reviews
- Small-but-Mighty! Long wallet, phone, AirPods all fit and still plenty of room."
- I always get compliments when I have them." I love the futuristic look of the buckle."
- The product has lost none of its shape even after three weeks of daily use. The pebble leather is durable and won't show scratches."
- It would be perfect if it could be used on either the left or right shoulder. It's a shame it's only for the left shoulder."
- The size is smaller than I imagined. If you want to put a Switch or a 500 ml bottle in it, the 156 City is more suitable."
