When I ordered this backpack, it was on backorder. I checked a couple of times on its progress, the replies were prompt and correct. The backpack itself is beautiful. The fabric, the stitching and zipper are strong and should last for years. It is a great size- practical for work stuff daily, and large enough to pack for a weekend away. I will happily order from this company again.
This cap is solid, adjustable, comfortable and very well put together. The fit is comfortable, the stitching is strong, the look is great. I'd buy anything from Pilots HQ!
