A general-purpose pouch is the workhorse of any carrier or chest rig loadout — the catch-all compartment that holds whatever the mission demands but that doesn’t justify a dedicated pouch. Multi-tools, Rite in the Rain notebooks, compass kits, chemlights, zip ties, snacks, spare radio batteries, medical overflow — all of it lives in a GP pouch. The design challenge is keeping that flexibility without devolving into a disorganized dump pocket where gear disappears. The T.REX GP pouch line solves this by building internal organization into a soft, non-specialized shell that mounts anywhere MOLLE or loop fields exist.
The Role of a GP Pouch in a Loadout
The core philosophy behind a coherent loadout is that every piece of gear has a known position. Dedicated pouches handle magazines, tourniquets, radios, and IFAKs. But a loadout that only has dedicated pouches is brittle — it can’t absorb mission-specific items without ad-hoc solutions like taping things to the carrier or stuffing them into plate bags. GP pouches provide the structured flex space that makes a loadout adaptable without becoming chaotic.
Where you place GP pouches matters. The general principle of pouch placement and load balance applies: GP pouches should not sit where they interfere with magazine reloads or weapon manipulation. Common placements include the rear panel of a plate carrier, the side cummerbund, or the back panel of a chest rig. On belt setups, they can supplement or replace a utility pouch when more volume is needed.
A GP pouch is also where admin pouch contents overflow when the admin pouch is already carrying pens, notepads, and protractors. If you’re running a land navigation kit, a GP pouch is the natural home for a protractor, map markers, and a folded map section, keeping the admin pouch free for items you reference more frequently.
T.REX GP Pouch Line
T.REX produces three GP pouches, each addressing a different volume and mounting requirement.
Vertical GP Pouch
The original T.REX GP pouch, designed around the Quad Flap Chest Rig but compatible with any standard MOLLE platform. It occupies three columns of PALS webbing and stands 7.5 inches tall, 5.5 inches wide, and 2 inches deep at 4.9 ounces. The defining design feature is internal organization: a half-zip main pocket that prevents items from spilling out during access, a 5” × 3.75” internal loop field for hook-backed items, four tie-down loops for securing critical gear, and an internal divider pocket sized for maps or Rite in the Rain notebooks. Two separate front zipper pockets (3” × 4” each) provide dedicated compartments for smaller items like batteries, chemlights, or ear plugs — items that would otherwise sink to the bottom of a single-cavity pouch. An integrated 2.25-inch belt pass-through makes it compatible with the T.REX Speed Belt, bridging the gap between carrier-mounted and belt-mounted utility storage.
Doublestack GP Pouch
The Doublestack is the successor to the Vertical GP — taller, with an updated feature set. At 8” × 6” × 2” and 4.6 ounces, it mounts across three MOLLE columns and seven rows. The key evolution is the front pocket material: Tweave, a four-way stretch fabric that expands to accommodate bulky items without permanently consuming space the way a rigid pocket would. This is particularly useful for items whose volume varies, like folded gloves, a balled-up shemagh, or a compressed rain layer. Inside, the mesh divider provides at-a-glance visibility so you aren’t blindly fishing around. The internal loop field and four paracord tie-downs carry over from the Vertical GP. The belt pass-through is sized for 1.75-inch belts. Posi-lock zipper pulls with heat-shrink tubing eliminate the rattle and accidental opening that plague standard zipper pulls — a small detail that matters when you’re moving through brush or riding in a vehicle.
Sticky GP Pouch
The Sticky GP takes a fundamentally different approach: instead of MOLLE attachment, it uses hook-backed stabilizer wings that grip any loop surface. Designed specifically around the Ready Rig and KYWI-style placards, it works on nearly any carrier or chest rig that exposes a loop field. The hook field is 4” × 9”, the pocket is approximately 5” × 8”, and the front features a 3” × 5” loop field plus a 1.5-inch elastic holder. The stabilizer wings add surface tension that prevents the pouch from peeling off under load or during movement — a common failure mode with simple hook-and-loop pouches.
The Sticky GP serves a different use case than the MOLLE-mounted pouches. It’s an organizer more than a fully enclosed pouch — ideal for tools, pens, batteries, and small flat items that you want to stage inside a larger compartment or on the interior face of a carrier panel. Think of it as the insert tray in a toolbox: it keeps small items sorted and accessible rather than loose.
Selecting the Right GP Pouch
Which GP pouch to run depends on the loadout and the mission.
For a patrol or field loadout built on a plate carrier like the AC1.5, the Doublestack is the default recommendation. Its Tweave expansion, mesh divider, and generous volume handle the range of items a field loadout demands — nav tools, batteries for optics and radios, food, gloves, and miscellaneous consumables. Mount it on the rear panel or cummerbund where it won’t interfere with front-mounted magazine access.
For a chest rig loadout like the Quad Flap, the Vertical GP is the native choice. Its slightly smaller footprint and integrated belt pass-through make it versatile across mounting positions.
For a minimalist or reconfigurable setup — particularly the Ready Rig or any placard-based system — the Sticky GP fills the organizer role without committing MOLLE real estate.
Whatever GP pouch you run, the principle is the same: know what’s in it, know where everything sits inside it, and practice accessing it under stress. A GP pouch you can’t efficiently navigate defeats its purpose. The internal organization features — dividers, loop fields, tie-downs — are there to be used. Take the time to set it up deliberately, the same way you’d configure a medical loadout or stage tourniquet pouches for access under pressure.
GP pouches also interact with the broader loadout layering concept described in Building a Coherent Loadout from EDC to Full Kit. At the EDC layer, pockets and a get-home bag handle general-purpose carry. At the belt layer, utility pouches fill the role. At the carrier layer, GP pouches take over. Each layer should complement, not duplicate, the one below it.
Attachment Methods
The MOLLE-mounted pouches (Vertical GP and Doublestack) weave through standard PALS webbing. For a refresher on attachment methods and compatibility considerations, see MOLLE Attachment Methods and Spacing. The Sticky GP relies on hook-and-loop friction, which is lighter and faster to reconfigure but less secure under extreme loads than woven MOLLE attachment. For most GP pouch contents — items measured in ounces, not pounds — the hook-and-loop grip with stabilizer wings is entirely adequate.
