You get this text: "Honey can you pick up some [insert domestic item here] on the way home?" Unless you're already wearing a backpack, you've had to respond in the negative. No longer, this little bag fits under your seat and can totally manage a dinner's worth of groceries and beverages. Read how in this Aerostich Lightweight Portable Bag review.
This is a usefully-sized bag made from a thin, but strong ripstop nylon. There's grab handles on top, the bag tucks into its own 4.5-inch wide, 2-inch thick pouch for stowing and webbing straps perform double duty, passing over your shoulders and in turn, pulling the top of the bag closed. There's well-designed pinch closures on those, making it easy to pull the bag tightly to your back in order to carry it securely.
That may sound incredibly simple, but there's no other product like this in the world. As with all Aerostich products, the reason for that is simple: quality.
Before I lost my last one (left it under the seat of a press bike when I returned it), I'd used it for about five years. While no, that wasn't every day, it was an awful lot of bottles of wine, packs of meat, random dinner ingredients, late night tacos or quick errands on the way back to the office from lunch. I think the biggest load I ever tasked it with was a twelve-pack of beer bottles, two steaks, salad materials and a pint of Ben and Jerry's. It managed that for a few highway miles, then a short ride up through the Hollywood Hills.
While the LP Bag is by no means intended to be a regular use bag, it's still built to perform above and beyond what a simple reusable grocery bag could ever do. This means that when you need to rely on it, it will hold more than you expect, hold it securely and not flap around even at relatively high speeds.
