The 150 Daypack is very good. I love it. It is high quality with genuine leather, the only drawback is the high price. Other than that it is a great backpack and I can recommend it.
GRAMS28 OFFICIAL
It took me over two years to decide to replace my original Tumi all-leather backpack. I was looking for a slim, business-looking bag with high quality leather and easy-to-use compartments, and I came across this backpack and decided to invest in it. I just received the bag, so I will have to wait and see how durable it is, but the construction and storage design exceeded my expectations and I was able to fit my AirPods Max in it with room to spare. The cushioned strap is also unusually comfortable. I am impressed with both the product and GRAMS28's customer service and believe I have found a long-lasting companion.

GRAMS28|Frequently Asked Questions (FAQ)
- How can I enjoy the leather as it ages?
-
GRAMS28 products are made of full-grain leather, which becomes more and more durable as it is used. In particular, vegetable-tanned "snowflake leather (vacchetta leather)" will develop a color and gloss in a few months and grow into an antique-like texture. Pebbled leather and nappa leather also start out matte, but as they are used, the surface becomes shinier, softer, and more comfortable in the hand. However, direct sunlight and oil may darken the color, so be aware of the storage environment if you want to enjoy an even change in color over time.
- Can it be wet in the rain? Is it waterproof?
-
GRAMS28 leather has a light water-repellent coating on the surface, so a light rain will not cause any problems if wiped off quickly. However, prolonged heavy rain or submersion in water can cause stains or discoloration. When using the product in the rain, it is recommended to use the waterproof cover and water repellent spray that come with the product. If it should get wet, let it dry naturally in the shade, and once dry, moisturize it with leather conditioner to maintain its original texture.
- Isn't it heavy for a leather product?
-
Full leather products are generally heavier than nylon products, but GRAMS28 has made them as light as possible through its unique structural design. For example, the 150 Daypack weighs approximately 1.6 kg, which is not lightweight, but it has the advantage of not losing its shape even when not loaded. 156 City Sling and 157 Essential Sling are light at around 500 g, which is comparable to the weight of a fabric bag. The luxurious feel and moderate weight of leather is a characteristic of GRAMS28 products, and we do not hear many people say that they are too heavy. If you are still concerned about it, you can choose a smaller sling model, folio, or other lightweight item.
- How do you take care of it?
-
Basically, just wipe it dry with a soft cloth, and if it gets dirty, wipe it off with a tightly wrung cloth. Periodically (once every few months), apply a thin layer of colorless cream for leather to keep the leather moist and to increase its luster. However, on glossy nappa leather or colored leather, some types of cream may cause uneven coloring, so please test the cream on an inconspicuous area before use. Waterproofing spray should be applied when the leather is new and every few months to prevent water and dirt from staining. GRAMS28 leather is highly durable and will retain its beauty for many years with proper care.
- Is there any repair or warranty support?
-
Yes, GRAMS28 offers a Lifetime Warranty on all of its products. Any defects that occur under normal use (e.g., unraveling of threads, malfunction of metal fittings, etc.) will be repaired or replaced free of charge. One user actually said, "I had a problem with my leather case, but they quickly replaced it with a new one. In the case of deterioration of leather over time or excessive damage, the repair may be subject to a charge, but the peace of mind of knowing that even if a charge is incurred, it will be taken care of will be great. Inquiries can be made through the contact form on the official website, and requests from Japan are also handled promptly. This kind of generous support system is a great point because this is a product that you want to have a long-lasting relationship with.
