Skarab 18L Backpack

Exploring new and familiar trails just got easier with Osprey's Skarab 18 Hydration Pack. With a minimalist design, the Skarab 18 is great for light and fast day hikes, mountain biking, and around town wear, while the addition of a foam framesheet with center stiffener makes the Skarab capable of comfortable carrying up to twenty-five pounds.

The main compartment is easily accessed through the front zippered panel, and the stretch side pockets are great for stashing water bottles—although, the included 2.5-liter hydration reservoir is typically capable of carrying all the water you'll need for a full day in the mountains. Osprey kept the look and design of the Skarab streamlined, with just two side compression straps and a front bungee cord that can be used to secure everything from light layers to trekking poles.

Sweet backpack but uncomfy waist strap

I've used it several times

The waist strap connection point is attached in a way that it just digs into my waist. Instead of sewing the straps directly to the backpack they sewed on a tightener then sewed the strap to that causing it to jet out and rub against my back.
