The King of bivy hunting backpacks.

The upgraded METCALF is a versatile workhorse with enough volume for a week in the field but compressible enough for an afternoon stalk. Built onto our Guide Light MT™ Frame, the METCALF has ample heavyweight capacity, and the OVERLOAD® feature keeps bag contents clean when packing out game. With a detachable lid, dual stretch-woven side pockets and full-length side zip access, this pack is a favorite among hunters looking for versatility and all-around utility.

Key Attributes

The new GUIDE LIGHT MT™ FRAME (Mystery Tech) continues the load carriage tradition of the tried- and-true Guide Light Frame™ and its rigid yet dynamic frame system, but with a few discrete changes. Utilizing custom-developed SJ Autolock buckles throughout, this new hardware collection provides the perfect blend of strength and weight. The 500D Light Plus fabric delivers high tensile and tear resistance, key characteristics for a robust, purpose-driven hunting frame.
The five-point waist belt incorporates the highly functional Redirect system and delivers solid weight distribution and eliminates slippage over your hips, regardless of the load.
OVERLOAD® feature provides functional expandability via a load sling between the pack and the frame, allowing you to put the bulk of the weight closest to your back for optimal comfort.
The patented Futura Yoke easily micro adjusts to the torso length allowing the proper amount of stand-off between the back and frame.

Getting Your Size

The key to a confortable pack load is the properly fitting backpack. We've designed a more custom fit into our packs with simple sizing based off two measurements. To find the appropriate size waist and york for your pack, collect the following two measurements, then reference the sizing chart below.

Waist Circumference
Measure around your waist just above the top of your hip bones (roughly two fingers below your belly button).

Torso
Use a tailors tape measure or string and have a friend measure between the bony bump at the base of your neck (C7 vertebra) to the spot on your spine that is just behind your belly button.
