Compare the Six Moon Designs Wy'east Daypack and Flight 30 Ultra Running Backpack to find the right 30L pack for your adventures, whether you prioritize ultralight day hiking or fast-paced trail running.
Quick answer
Choose the Wy'east Daypack for versatile day hiking and casual use, or the Flight 30 Ultra for speed-focused trail running and fastpacking where minimal weight and a secure fit matter most.
Weight and intended use
The Wy'east Daypack weighs just 20 oz (580 g), making it one of the lightest daypacks available. Its simple design prioritizes versatility for hiking, travel, and everyday carry. In contrast, the Flight 30 Ultra is slightly heavier at 26.2 oz (743 g) but includes features tailored for high-intensity motion, such as multiple harness options and an adjustable torso to dial in fit during running or biking.
If you need a pack that can handle a variety of activities without being overbuilt, the Wy'east offers a lower weight and a spacious main compartment with deep pockets. If you're logging miles on trails or mountain biking, the Flight 30's extra ounce and a half buys you stability and comfort at speed.
Fit and adjustability
The Flight 30 Ultra offers multiple harness options (vest or shoulder harness) and an adjustable torso, so you can customize the fit precisely. This is critical for active sports where the pack must not shift. The Wy'east Daypack has a simpler design with no harness options, which keeps weight down but limits fit adjustments. It works best if you already know your torso length and prefer a straightforward setup.
For runners or cyclists who need a snug, bounce-free carry, the Flight 30 is the clear choice. For hikers who value simplicity and a lower price, the Wy'east's fixed fit is often sufficient.
