2 sources$110as of Oct 17

The CamelBak Rim Runner 22 includes a 2.5L CRUX hydration reservoir and offers extensive organization with multiple zippered compartments, though it weighs significantly more than competitors at approximately 32 ounces (1.59 lbs). OutdoorGearLab found the included bladder to be a strong selling point that eliminates separate purchases, while Nailthetrail confirmed the secure mounting prevents shifting during use. However, compression straps cross over zippers, impeding quick access to main compartments, and side mesh pockets are prone to tearing under stress or when carrying sharp items. The fully adjustable sternum strap accommodates varied torso lengths for a precise fit, but soft waist belt construction reduces effective weight transfer compared to stiffer competitors. This pack fits hikers who prioritize durability and organization over minimal weight, while those seeking ultralight performance should look elsewhere.

Strengths
  • — Includes a hydration reservoir (2.5L CRUX or Antidote) eliminating the need to purchase one separately.
  • — Offers extensive organization with multiple zippered compartments, side mesh pockets, and front stash overflow.
  • — Constructed from durable materials including dense fabric on the bottom and strong tight-woven mesh on the sides.
Watch-outs
  • — Weighs significantly more than competitors, rated as one of the heaviest packs in its class at approximately 32 ounces (1.59 lbs).
  • — Straps and compression buckles cross over zippers, impeding quick access to main compartments.
  • — Side mesh pockets are prone to tearing under stress or when carrying sharp items.
Osprey Skarab 18
Ranked #4 in Best Hydration Packs
Osprey Skarab 18
1 source$159.99as of Oct 17

OutdoorGearLab found that the Osprey Skarab 18 includes a high-quality 2.5-liter HydraPak hydration system paired with an efficient bite valve and magnetic hose attachment point, delivering water with comfort during active use. The pack offers ample storage for day trips but suffers from limited internal organization, consisting mainly of a single large compartment without dedicated pockets for gear segmentation. Reviewers also noted that the short hanging clip in the hydration sleeve makes removing and replacing the bladder cumbersome when refilling at trailheads or sinks. This versatile 18-liter capacity suits hikers seeking an all-around daypack with sustainable materials, while those prioritizing easy maintenance or extensive internal organization should look elsewhere.

Strengths
  • — Includes a high-quality 2.5-liter HydraPak hydration system with an efficient bite valve and magnetic hose attachment point.
  • — Offers a large 18-liter storage volume capable of carrying extra layers, shoes, or lunch items for day use.
  • — Constructed from sustainable bluesign-approved recycled high tenacity nylon materials.
Watch-outs
  • — Provides limited internal organization, consisting mainly of a single large compartment without dedicated pockets for gear segmentation.
  • — The hydration sleeve uses a short hanging clip that reviewers found difficult to use when removing and replacing the bladder.

How they stack up

CamelBak Rim

The CamelBak Rim offers extensive organization and a durable build but weighs significantly more at approximately 32 ounces compared to the Osprey Skimmer 16's ultra-lightweight 1 lb profile. While its sternum strap is fully adjustable along daisy chains for precise placement, it lacks the integrated rain cover found on the Osprey Manta 24 and suffers from compression straps that impede zipper access.

Osprey Skarab 18

The Osprey Skarab 18 provides a large 18-liter volume but suffers from limited internal organization compared to the CamelBak Rim's multiple zippered compartments. Its hydration sleeve uses a short hanging clip that reviewers found difficult to use, whereas the USWE Rush 8L includes a bladder with a wide-mouth opening for easier filling and cleaning.
