If there’s one thing Hyperlite Mountain Gear does better than almost anyone, it’s building packs that disappear on your back. The Aero 28—released in 2025—is their latest evolution of the ultralight fastpack. It’s a 28-liter minimalist design built for those who hike farther, move faster, and demand gear that can keep up.
Weighing under 18 oz, the Aero 28 merges running-vest agility with true backpacking structure. Whether you’re tackling a multi-day fastpack, a quick alpine push, or a section of the PCT, this pack gives you everything you need—and nothing you don’t.
Design & Materials
The Aero 28 is made from Dyneema Composite Hybrid (DCH), a signature Hyperlite material prized for being both ultralight and nearly waterproof. It features:
- A vest-style harness for balance and comfort at speed
- A roll-top closure for adjustable volume
- Stretch mesh exterior pockets for snacks, bottles, or layers
- Minimal back panel padding for stability and airflow
- Elastic side compression cords for load control on technical terrain
The build quality is what you expect from Hyperlite—precise stitching, clean lines, and smart material choices that handle rough miles and unpredictable weather.
Trail Performance
On the trail, the Aero 28 feels like an extension of your body. The vest-style straps hug the torso without restricting breathing, while the load stays centered and stable—even when scrambling or running.
This pack truly shines in 1- to 3-day ultralight missions where base weights stay below 10 lbs. It can comfortably handle 20–22 lbs total before feeling overtaxed.
“It’s a pack that makes 20 miles feel like 15,” said one early user on Hyperlite’s forums. “I stopped thinking about my pack by lunchtime—and that’s the whole point.”
