Hello... In firs place I´m not sponsered by Lowepro . . . ( I wish. . . ahahahahahahahahah ), but I have to say, this is the best brand that you can by to protect all your gear, I use/used always Lowepro Bags , I started whit Lowepro Flipside 300 for some time but my gear grow up so I needed a bigger backpack now I´m using an Lowepro Flipside 400 AW , very confortable to use eving when it´s full and you are walking for several hours .
I use another Lowepro for carring my ND Filters from Lee Filters, they are a too expensive, so I must protect them well and for this I use a Lowepro S&F Filter Pounch 100, you can atach her in you belt etc. , very easy to use, pratical and very good to protect your s ND Filters, so, this is my modest review for Lowepro, if you have any douts visit the website of Lowepro.
