Light Hammer Nylon

This fabric is named for its almost hammered looking surface. Made to our specifications to be light and strong. It feels dry and crisp like our Hammer Nylon, but is thinner for an effortless daily bag. The fabric surface feels natural but it has the strength of nylon. This high density improves the water resistance of nylon. Light Hammer Nylon fabric is created using a proprietary process invented and made in small batches in Japan.

Vegetable-tanned cowhide

To increase the strength in the traditional way this leather was shrunken. The shrinking process make the leather fibers more dense and imparts a soft flexibility. The signature of shrunken leather is the irregular ‘pebbly’ surface grain that varies from skin to skin.

How We Dye Our Leather

There is quite a bit of variation from skin to skin and even within the same skin. The typical way to make leather color uniform is to cover the surface with thick synthetic fillers and pigment coatings, covering the natural variations in surface and color. Unfortunately this finish does not allow scratches to blend in or improve over time. Postalco leather is colored using aniline dyes. Aniline dyes soak into the leather leaving visible the natural variation in grain and texture. The more aniline dyed leather is used, the better the surface patina gets over time. Each skin is different: a faint stripe-like pattern, called ‘tora’ in Japanese is a natural effect due to the way the dye soaks in to the various parts of the skin. Each skin's tora is different. Making Veg tanned and Aniline dyed leather is more expensive and time consuming but produces beautiful leathers.


Leather and fabric webbing may fade with use and colors may bleed, especially when wet. If your bag gets wet gently blot it with a soft dry cloth. Do not wash this bag. Do not place in the dryer. To clean: Spot dry clean or wipe with a moistened soft cloth. Using water repellent spray made to be used with both leather and fabric. If the leather feels dry please use a mild creme (such as clear Delicate Shoe Cream) to replenish moisture. Be sure to use only clear cream as any color will rub off!

素材は「ハンマーナイロン」というもので、まさにハンマーでたたいたような加工だ。これがとてもハリがあって、荷物を入れずに空っぽ状態でも自立してしまう。リュックにしては少々高めだ。ただ、これまで使ってきたポスタルコ プロダクトは長く使えるという印象を持っている。一番長いもので、「リーガルエンベロープ」はすでに12年目を迎えている。長く使えると共に深い味わいが出てくるのも魅力だ。きっとこのリュックも10年くらいは軽く使えると思う。それを考えれば決して高くはない。いい買い物をしたと大満足している。

Three large pockets
When everything ends up in one large backpack pocket, it’s like a basketful of fish: it is hard to find the one thing you want. This backpack is divided into three large individual compartments to keep contents in easy to access zones.

Cushioned pocket
The main compartment contains a cushioned pocket that fits a laptop (up to a 16" MacBook Pro) and other papers.

Front zipper pockets
The two large zipper pockets on the front are made with dividers that will keep the pocket volumes open even if the other pockets are filled.

Designed for comfort
When carrying any weight in a soft backpack, often the bag uncomfortably sags away from the wearer's back. Frame structures or thick foam cushions, used to prevent this problem, end up reducing valuable storage space in the pack. We developed an original design that keeps the bag closer to the back without bulky frames or overly thick cushions. The shoulder straps connect and continue to the bottom of the bag, structurally supporting the contents.

Feels good in hand
Double leather-wrapped handles on the top make it easy to carry this bag by hand, and long leather zipper pulls allow the bag to be opened and closed while wearing gloves.

Quick access pouch
The bag's top surface has a quick access zipper pouch large enough to hold a wallet, phone, and other essentials.

About Bridges
Gustave Eiffel who made the Eiffel Tower was a bridge specialist. To build the world's tallest tower he applied what he knew about bridge making. He really took a horizontal thing and made it vertical. Inspired by the way that a bridge divides and balances weight we made these lightweight bags that don't hide their structure. There is a single layer of fabric supported inside with a series of webbing straps. The lightweight architectural strength of the Postalco Bridge Bags is combined with our original Hammer Nylon fabric.

Carrying research
Even in different ages and cultures, people’s methods of carrying on their backs are strikingly similar.

Thinking of handles
We design handles to match human hands, but our hands themselves are so flexible that handles can take on many shapes.

Swimming hands
I can't help but think that an octopus looks a little like a swimming hand. A human hand and an octopus are completely different but they both seem to have adopted at a similar shape. An octopus's branched body makes it adept at squeezing in and around a variety of spaces. The human hand is also able to adapt to so many different shapes, blending with the many objects it comes into contact with daily.

Staying the same
100 years apart but still carrying in essentially the same way.

Clever storage and easy access
Ever feel like you have a small house on your back? A backpack is like carrying a small house.

Object Layers Around the Body
Marshall McLuhan writes about objects that we use around us as extensions of our bodies. The wheel is an extension of our feet, telephones are extensions of our voices, and hats are extensions of our hair. Each thing we add to our bodies is an attempt to fill in some missing need. Will our bodies ever be complete?

Light Hammer Nylon
This fabric is named for its almost hammered looking surface. Made to our specifications to be light and strong. It feels dry and crisp like our Hammer Nylon, but is thinner for an effortless daily bag. The fabric surface feels natural but it has the strength of nylon. This high density improves the water resistance of nylon. Light Hammer Nylon fabric is created using a proprietary process invented and made in small batches in Japan.

Learning from Japan
The craftspeople, suppliers, and small workshops found in Japan make things not to be found anywhere else. We are fortunate to work with family businesses that are so focused on their craft. Don’t put Postalco items on a shelf or in a drawer. Their beauty is revealed through daily use. They will help you feel good at home and be ready in a meeting.
