Ultralight wonder

This pack is amazingly light. Weighs almost nothing but carries a decent load. The vest harness is comfortable and stays put. Great for fast hikes.

Best daypack I've owned

I've been using this on trail runs and day hikes. The 20L is just right, the pockets are well-designed, and the back panel breathes well. It feels like a second skin. The price was fantastic.

Great pack, but small

It's very light and well-made, but 20L fills up fast. For a minimalist like me, it's perfect. But if you carry a lot, consider the 40. Overall, I like it.

Excellent for summit hikes

Took this up a 14er and it performed flawlessly. The pockets on the shoulder straps held my phone and snacks. The pack didn't bounce even on steep sections. Very happy.

A bit too minimal for me

The pack is comfortable, but the lack of padding on the bottom is noticeable when you set it down. Also, the hip belt pouches are tiny. But for the weight, it's a tradeoff.

Love the vest harness

The fit is amazing – no more swaying. The zippered chest pockets are so convenient. I've used it for a 20-mile day hike and barely felt it. Great pack.

Good value

Great pack for the price. It's light and has enough features. I wish the water bottle pockets were deeper, but it works.
