Product description

High on a ridgeline, winds swirling around your perch, the stability of your pack and gear is of paramount importance'that's why a pack like the Osprey Mutant 38 Backpack is so important. Support and stability come in the form of a removable HDPE framesheet, a removable aluminum stay, and an AirScape back panel that also ventilates as you climb. This top-loading pack features a removable floating top lid to lighten your load for summit day. When removed, you can protect and secure your gear with the FlapJacket closure system. To help you haul everything you need, Osprey added its Mutant Dual ToolLock ice-tool system that lets you securely carry, and remove, tools when needed. Side compression straps let you secure your load if it's not quite full, and the A-frame ski carry makes sure that you can get down off the top the fun way. To help keep you from overheating on the way up you can store your helmet in the removable helmet-carry system up top.

OSPREY - Mutant 38

Used this pack for the past couple of years on summer trips. Easy to pack, has H2O port for a bladder. The top pocket/lid can be removed completely giving a large pack that will fit into flight overhead lockers. Plus the same top pocket setup for helmet carry. Lots of nice touches and features.
Downsides are minor - no side zip to access the bottom of the pack whilst out and about. Small size is 36L vs the Large 38L - but not that you would notice.
