Such a Great Bag to use as a Daypack.

Such a Great Bag to use as a Daypack.
My recent grad is spending a few weeks in Europe. He needs a bag to carry when he is out is wandering towns and as a personal item on the overseas flight. He needs to be able to carry his IDs, sunglasses, hat, sweatshirt, water bottle, some chargers, maybe a Switch and a few snacks but he doesn't need a big padded backpack. He doesn't need a ton of compartments. This is nearly perfect for a daypack (or as close to perfect as they are making). The bag itself is light-weight, weather resistant, and a bit larger than a standard drawstring sack. It is durable and has just enough pockets. My husband (40+) isn't a fan of strings for straps but the kids really are. This bag feels like it will be ideal. I like that there is a pocket with soft fabric at the top for sunglasses. I like that the secondary compartment is large with two small interior pockets (those have his charging cords and gum). Also in the secondary compartment, I threw a couple of mesh bags with extra meds, bandaids, tissue, lip balm, tooth brush, some silverware, etc... With the bag organized like this, he will have plenty of room to toss randomness into the largest main compartment. I realize that I've over done this and yes, my 18 year old son is just like most boys. He will probably forget he has these convenience items with him and eventually the bag will just be a big mess of wrappers and water bottles... but I'm a mom who is more than a little "extra"... so on that note:For the Under-Armor designers... The bag is AMAZING, but consider adding a hook inside the main compartment of the bag so that keys could be carabiner clipped inside. And maybe one more pocket: Inside the main drawstring area should be a small zip pocket that will hold a passport & cash/credit cards (maybe even phone). It isn't real safe to keep those items in an outside zipper pocket and it is a pain to fish around in the bag for them... I think to make due, I'll just link a few carabiner clips to the drawstring and hang the RFID passport wallet inside the main compartment but it isn't ideal. I'll keep thinking... and I'll try to remember to update this review after the sackpack has survived a month in Europe.Update: It easily survived a month in Europe and looks brand-new. My son liked it but said the thin straps were hard to use all day. They'd start digging into his shoulders if there was heavy stuff like a water bottle & jacket in the bag.

Very helpful backpack, very good looking, very good quality, very light, very large capacity, shoulder straps are also very soft, I first bought 2 for my children, used for football lessons, football and cups; and then when I went swimming, I also carried this bag, wet swimsuit, big bath towel, all very easy to use; the outer 2 compartments can make my mobile wallet and wallet completely separated from the wet swimsuit; so I bought a third, it was amazing
