The Arc'teryx Pali features a unique rolltop design that is common in packs (especially Arc'teryx packs) but has not been seen before in rope bags. The Pali was also the first rope bag to be specifically designed to fit perfectly into a pack. In this case it's specifically designed to fit exactly into an Arc'teryx Miura 50.
It features one of the larger tarps (4'x 4') in the review and is also a compact size that makes fitting the Pali into the bottom of any pack easy. The flip side for such a small package is the Pali can be a struggle to fit in a 70m rope easily. Even with a 60m cord we couldn't fit in much else with it. It is also the most expensive rope bag in our review.
Even with a 60m rope, you can't fit much else in. The biggest plus is it does fit neatly into the bottom of most packs, making the Pali a great choice for climbers who always carry their rope bag in their pack. We even found it fit well in smaller sub 40L packs. If you already own or plan on buying a Miura 50, then it's a sweet design and you won't waste extra space.
