ATD1

A Classic, updated.

The ATD1 Backpack was launched in 2018 as the result of years spent traveling, developing soft goods and field-testing them in cities, deserts and forests all over the world. No matter if it's a one bag weekend escape, a long term travel or your daily commute, we wanted this pack to be your ultimate travel and EDC backpack and make you carry better.  

The ATD1 is intended to be versatile and has a discreet look to blend in any setting. Thanks to its emblematic expandability, it's compact enough for EDC use when compressed and spacious enough for months of one-bag traveling. 

In other words: travel, work, play, all in one bag, Comfortable to be carried for hours, designed with clever pocketing (enough pockets to store your stuff, not enough to lose it), it is protective from weather or unwanted access while still being accessible for the user. Most importantly, it is built to be durable, therefore it is sustainable and will survive decades of everyday use.

During the last 6 years it went on 6 continents, ranging from war zones deployments to long term backpacking travels. It was dragged, abused, strapped to motorbikes sides and trucks roofs. In between, it was used as an EDC bag for short trips and daily commutes, reporting zero materials and manufacturing fail or any QC issue that could affect use. It has a really low rate of second hand sales on backpacks communities, subreddits and Facebook groups, showing that this is an object users tend to stick to.

Features

Since its first launch in 2018, we did some small changes in materials, construction or branding at each run. In late 2023, at its 5th production run, the pack featured a completely redesigned bottom construction with a less slanted angle and less stitches facing the ground, new laminated and 100% recycled fabrics for shell and liner, angled shoulder straps attachment points to contour even better to human shape and widened distance between them and load lifters, making these even more efficient at managing the load while allowing also shorter torsos to find it comfortable. Plus, this run will feature Roll top stiffeners to help closing the pack, new "ATD" tonal embroidery for an even more subtle branding, Aluminium hardware on compression straps to open them in a breeze, Stretch side pockets to make easy to use them even when the pack is full and luggage pass through on the back for rolling luggage handle compatibility.
In 2024, with not so much left to change, we still managed to adjust distance between shoulder straps to make the pack more comfortable even for smaller frame people, make side compression straps removable, simplify the front compartment, adding a new aluminium key hook and changing the fabric used for back panel's padded portions and shoulder straps. These are now made out of Challenge Sailcloth RBC®600 instead of EPLX®600 like the rest of the pack. RBC®600 is the exact fabric used on the outer face of its Ecopak® laminated counterpart, a 600d plain wave, post consumer recycled Polyester canvas, PU coated and impregnated with eco-friendly C0 DWR treatment, but not being laminated it is more flexible, leading to less risk of cracking in corners (especially those of padded areas).

Break In 

Rome wasn't built in a day, nor is your pack's fit. Compared to 500d Cordura®, ATD1's new laminated fabric is more structured and stiffer: at the beginning, the pack feels rigid and shoulder straps may feel stiff to some: time and use will allow materials to stretch and conform to your body. Plus, Curv® frame sheet is straight when new but will shape on your back with regular use, thanks to your body heat. Just load the pack, tighten shoulder straps and use it daily to have it formed to your body like a good pair of jeans or a leather jacket: good, durable things take time.

Product Care 

Clean your pack with mild detergent and line dry it avoiding direct sunlight. Don’t use fabric softeners or bleach, don’t machine wash or tumble dry it. Outer DWR treatment may wear off over time but it is easily restorable with spray coatings for outdoor gear.
