Love the layout because I’ve used the Synapse 19 for years. Because of the durability i experienced with the S19 and thinking I could use one with a little more space. Unfortunately for me my son convinced me to give it to him when we shipped him off to college. He says it is perfect for toting his laptop, a couple of binders and notebooks, while separating and organizing all the other essentials for college kids now in the other pockets: Laptop charger, phone charger, headphones, water bottle, snacks, shades, gum, etc. and room to spare. So, I’ll probably save up for another one for me. Though I liked the x-pac on the S25 because of how durable and water resistant it felt, I will probably go with ballistic on my next one like my S19. The ballistic feels softer to the touch where the x-pac is a little more ”crinkley” and makes a little more noise when you manipulate it. I’m not sure if that was just because it was new and hadn’t broken in yet, but I do not remember thinking that with my ballistic S19 when it was new. If you are thinking of buying one, buy it. Great design, lasts a long long time, and great company that stands behind their products and their quality workmanship.
