The trad day pack I was waiting for
I'm so impressed with that pack. Before purchasing this one I had the Metolius Express Haul Pack 39L Both was or will be used mostly as a day pack at the crag. The Metolius as an oval shape and it's sometimes hard to put or remove big cams or a shit load of gear all stack together or helmet. Also, the capacity is some time to small for my standard need on trad crag. The Arco is really circular and is a lot roomier. The weird thing is there is an only 1L difference from what the manufacturer claims. But it's for sure more than 1L. I feel the Arco have 5 to 10 more litters. There is an upper padding on the back and many useful pockets. The 4 inside loops gear on the top works like a charm. It prevents all the trad gear to stack together. This pack as more feature than the Metolius and that's why it's heavier. But it worth it. I did not use it on direct sun but I'm worried the pack could be hot with that black color.
