After a year or so of use, I think I'm ready to leave a review. The Nest backpack has been awesome and I love the sleek design and compactness. That said, there are some things I wish it had. 1) Fix the Main compartments zippers, they are difficult to zip most of the time and the pack material frequently gets pinched in the zipper. 2) Side drink pouch is slightly too small and not deep enough; it only holds a certain sized items and the expandability is way too limited. Depending on the material of the item, it may not hold well in the pouch and may work itself out. 3) The pack could use more useful interior pouches. 4) The pack needs a slightly deeper top compartment. 5) I wish it had an expandable main compartment feature (of about 0.5"). 6) Another D-Ring on the opposing shoulder strap would be nice vs. the useless sunglass retainer. 7) Another exterior side pouch where the cinch straps are (dtraps are useless to me and get snagged on stuff all the time). Despite everything listed above, it's still a solid pack, I just wish I could change a few things to make it even more useful without drastically changing the pack or going to the larger Hive pack. I still recommend this pack!
