My kids have used High Sierra Backpacks (Access Laptop backpacks) for years. STRONG and lots of colors, good sized, lots of pockets. We usually replace every 2 years due to normal wear. Once the kids hit high school STRONG was a requirement -- textbooks are extraordinarily heavy these days. Website has all the colors and types (certain stores only carry certain models). Had 2 of our Access backpacks rip in the same place: where the zipper attached to the top of the b. P on the front. Contacted CS at High Sierra as the backpack tags list a Limited Lifetime Warranty. Since our damage was due to normal use -- they replaced the backpacks for free! I did have to photograph damage, and send info about when purchased (2 & 4 years ago!). My claim was accepted and to have our replacements sent I had to cut a hole in both backpacks (to prove they were destroyed and so I didn't have to spend $ to send them in to company) and send a list of my 4 requested replacements. Both new backpacks arrived within a week of final pictures being sent! The 3 cs reps I talked to were all helpful, sorry our products failed, and very clear and concise over what I needed to do for replacement. They did NOT require an original sales receipt, just the tags from inside the bag to prove they were from High Sierra. More companies should take lessons from High Sierra: they stand behind their products, they made the claim and replacement process easy, they followed through on their warranty promises
