Love at first sight

When my Trail Blitz arrived the spark was instantaneous! It was love at first sight. I'm an avid day hiker and have been searching for something light weight, durable, and dare I say sexy....and finally I have found it. True love is real, and it's out there. Thank you Black Diamond.

All out Blitz

Had to get used to the economy size but soon adapted this many pack for the trailhead and then the bike 🚲 same outing. Use it solo or store it inside another pack for those expected and unexpected adventures.

Solid day pack for a quick weekend backpacking

It's light enough for a weekend backpacking trip. When packed into it's pouch, it's a bit big, probably better to roll it up or put it at the bottom of the backpacking bag. No regrets.

It's a superlight rucksack that you can stash in any luggage

This will hold a bottle or a bladder, a rainshell and a sandwich, a headlamp (like the Flare), some TP and a rescue blanket, a few trinkets and a bag of chocolates. Or it can haul a big lunch worth of groceries back from the store.

Great Little Pack

Perfect for light outings when your pockets aren’t big enough. Great for snacks and extra layers when it may or may not be too cold for shorts and a T-shirt. I use it Mtn biking and hiking for that reason alone. I disagree with other reviewers saying the quality is lacking. It’s light, not poor quality.

Bizarre construction

This is tiny with no give at all. Continues to be hard to figure out how to open it. The light color got clay soil stains on it for no good reason. Can't get 'em out. To boot, it's uncomfortable.

Great summit push bag

Bag is perfect size for a summit push after a day of backpacking. Lightweight, small, and easily accessible. Didn’t give it a 5 bc of the straps which are kind of flimsy but it’s perfect for the cost of the bag.
