Long story short, we've been thinking about ATD2 for years: intrigued by this challenge, we didn’t want to simply scale its bigger brother down. Even keeping expandability has a key feature, different size means different uses, different problems to solve, different settings to use the pack in. It had to be compact, conceived for fast uses, more commuter-friendly, more easily accessible, ideal for those short weekend trips (or longer ones, if you are minimalist enough), perfect for those who want (or have) to travel with a checked luggage and still need a compact, yet expandable, travel backpack to pair it with. This Pack will snugly fit 1 Large or 2 Medium ACU Packing Cubes, or 1 Medium sized cube with room to spare.Now at its 2nd production run, ATD team redesigned bottom construction with a less slanted angle and even less stitches facing the ground, angled shoulder straps attachment points to contour even better to human shape and add load lifters, making load management even more efficient while allowing also shorter torsos to find it comfortable. Plus, the pack now features a new aluminium key clip, the new ATD tonal embroidery for an even more subtle branding and removable compression straps to quickly get rid of them if not needed. To top all this, back panel padded portions and shoulder straps are now made out 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). Flexible volume adapts to any need and make the pack extremely versatile. U-shaped zipper on back panel allows for top, side and clamshell opening. Top quality materials and almost paranoid construction: we have zero report of an ATD2 that ever failed on his user. All fabrics are laser-cut (this is almost unique in the bags industry) to prevent any risk of fraying. Hidden or clean finished stitches protect both skin and thread from friction. Stretch parts are double layered to keep them snappy for decades. The shape maximizes internal space while keeping load close to the back. Expandable Roll top construction with stiffeners. One point closure with Fidlock® magnetic buckles help quick access. Enough pockets to store your stuff, not enough to lose it. Luggage pass through. Side stretch pockets conceal compression straps and fit water bottles, tripods and foldable umbrellas Top, sides and bottom handles. less stitches on liner construction to maximize rain resistance. Stretch sleeves keep laptops up to 16 inches suspended from the bottom. Main compartment has no access on front or sides for peace of mind in crowded areas. Front compartment has its own volume and effective organization (key leash, pen slots and two pockets). Removable compression straps for volume flexibility and to carry additional gear. Removable, Lightweight Curv® (self-reinforced polypropylene) frame sheet. Removable ambidextrous sternum strap and hip belt Inner Loops to hang any pouch with PALS. Paracord zippers pulls help access and reduce noise. OneWrap Velcro® removable strips for webbing management. PALS on bottom for a Bike light or pouch. Loops on the inside to hang an ASP Sling Pouch, an AFP Flat Pouch, or any pouch with PALS. Full size padded belt available as an add-on.
