Compare the ATP-1 and ATP-3 admin pouches by size, capacity, and organization needs. Find out which waterproof organizer fits your EDC gear best.

Quick answer

Choose the ATP-1 for a compact, waterproof pouch that fits small personal effects and survival items. Choose the ATP-3 if you need more space for organizing EDC tools, a single-stack 9mm pistol, and spare magazines.

Size and capacity trade-offs

The ATP-1 is small and boxy, ideal for items like fire starters, basic first aid supplies, or a small multi-tool. Its IPX7 rating and welded seams keep contents dry. The ATP-3 opens clam-shell style and can accommodate larger gear, including hook-backed shingles for custom mounting. It is better suited for carrying a compact pistol and magazines alongside your everyday carry tools.

If you need a low-profile pouch that disappears in a pack or pocket, the ATP-1 is the better fit. If you want a more versatile organizer that can serve as a mini range bag or tech pouch, the ATP-3 gives you that extra volume.

Material and durability

Both pouches are built from 600D RPET recycled material with fully welded seams, offering the same IPX7 waterproof protection. The material is rugged enough for daily carry and outdoor use. The main difference is the closure: the ATP-1 uses a standard zipper, while the ATP-3 features a clam-shell opening that lays flat for better visibility and access.

Key trade-offs at a glance

Portability: ATP-1 is compact and lightweight, ideal for pocket or small pack. ATP-3 is larger but still pouch-sized.
Organization: ATP-1 is a simple zippered box; ATP-3 offers clam-shell opening and MOLLE compatibility for custom inserts.
Capacity: ATP-1 fits small essentials and basic first aid. ATP-3 can hold larger tools and a compact pistol with magazines. If you need to carry a firearm or larger gear, the ATP-3 is the only option.
