Rainforest Waterproof Backpack

 

OPST Rainforest Backpack

Built for Anglers Who Pack Like They Mean It

Need more space than your hip or sling pack can offer — but still want something river-ready and purpose-built? Look no further than the OPST Rainforest Backpack — a modular, highly water-resistant daypack designed to handle everything from multi-hour hikes to boat-based missions.

With over twice the capacity of our original Rainforest Waist Pack, this rolltop backpack is the answer for anglers who carry a little more — whether it’s lunch, rain gear, extra layers, or water bottles, plus all the essential fly gear you never leave behind.

Key Features

Rolltop Design
Adjusts to your loadout while keeping gear secure and moisture out.

20L Storage Capacity
Roomy enough for a full-day kit without feeling bulky or overbuilt.

Modular Compatibility

Water-Resistant Construction
Built from the same durable, highly water-resistant fabric as our waist pack to keep your gear protected from splashes, spray, and showers.

Cinchable side pockets hold bottles or secure rods when paired with upper webbing loops.

Front Pocket with Drain Holes
Keeps wet or quick-access items separate and draining.

Gear-Ready Webbing & Loops
Outside web loops on both sides are compatible with carabiners, NRS straps, and 1” webbing — perfect for strapping on net holsters, dry bags, or extra gear.
