Maximum backpack with minimum capacity

The starting axis is urban use. From there, the backcountry is just out of reach.

JINDAIJI MOUNTAIN WORKS is now available in a Circles original version!

onedayboyslim is not a daypack downsized from a mountain backpack, but a daypack with gimmicks cultivated in the production of UL gear based on a daypack for city use.

Closed cell padding in the back and bottom. Plate-shaped padding on the back and U-shaped padding on the bottom absorb shock and reduce body twisting and distortion.

The onedayboyslim PC sleeve has a raised bottom design with a 5cm lift from the bottom. Together with the bottom U-shaped padding, it protects your laptop and prepares it for hard contact. A little freedom gained with only 7g of padding.

When you add a bottom pad to an ordinary backpack, you may be concerned about the bulkiness. However, the onedayboyslim, which looks ordinary but is not ordinary, has a slim body with a thickness of 8 cm. That's why the bottom pad is so effective. This is a coincidence.

The straps overlap from the sides to the back. This can be used in a variety of ways.

Snowshoes and a nickel on a snowy mountain
A roll of wool blanket at a picnic
Undressed insulated clothing
And of course a helmet.

When not needed, it can be fastened as a side buckle.

The lower part of the back pocket is gusseted. The two sleeves in the pocket are connected at the bottom, so you can use the battery cord to turn the battery cord from the sleeve. A key hook is provided on the top.

The side pockets on each side are intended to be used as gear pockets.
They are made of the same fabric as the body, instead of mesh pockets that are prone to tearing or fraying when rowing in the bush. Of course, it is sized to hold a 500ml water bottle, but it is designed as a gear pocket.

It has a total of eight loop tabs located on the body, top and bottom. The reflective bungee cord is threaded through the bottom when shipped, but can be ported to the top. When moved to the top, onedayboy's double slider allows access to the interior from the side without removing the luggage strapped to the top.
A chest strap and axe loop are also provided.

The colorful inner fabric brightens up the interior of the backpack and
makes it easy to find your belongings.

The design is also highly expandable with various other loops and tapes.
The backpack is also designed to be expandable with various loops and tapes to accommodate the user's original expansion needs.
