Sweetwater UL 28L Backpack

When you need to move fast and light without losing your gear organization, the Sweetwater UL 28L is our pick for trail runners and fastpackers chasing long days or ultralight overnights. UL construction drops pack weight so you feel it less on sustained climbs, while two torso sizes — S/M and M/L — keep the fit locked down when the pace picks up.

• 28-liter capacity works for long day hikes, fastpacking, and ultralight overnight missions without carrying dead space
• UL (ultralight) construction minimizes pack weight so you're spending energy on the trail, not hauling your bag
• Available in S/M and M/L torso sizes for a dialed, body-specific fit that doesn't shift on technical terrain or fast descents
• Organized internal layout puts gear where you can reach it — no single-compartment guessing games mid-run
• Mercury colorway keeps things low-profile and versatile, whether you're on trail or heading into town post-run
