27L army green backpack with collapsing compression closet, expands to 35L I purchased this backpack in conjunction with the suitcase with closet from the solgaard website in 2022. After various degrees of travel with both, I found the functionality of the closet much better with the backpack. this is great for a week long trip in summer or a slightly shorter trip packing bulkier items. plenty of room for a dopp kit and a few other items in the pack with the closet inside full and compacted. the material on the pack is very resilient, the inside provides just enough organization while still leaving the main large cavernous space. this pack is not full clamshell but I did not find it to be too much of a hindrance unless I had over packed the closet insert. this backpack is discontinued, see full details here: https://packhacker.com/travel-gear/solgaard/lifepack-endeavor-with-closet/
