AlpackaRaft Cargo Fly Roll-Top Inner Dry Bags — Small, Standard, and XL Size Guide

🇯🇵 日本語 | 🇺🇸 English

Which inner dry bag should you use in your Cargo Fly?

For most packrafting, a roll-top dry bag is the right answer. Lightweight, simple, reliable — the classic roll-top covers the waterproofing and organization needs of the majority of trips.

AlpackaRaft’s roll-top inner dry bags come in three sizes. Here’s how to choose.

The Three Sizes

Small (30L)

Compatible: Refuge, Scout, Valkyrie

Sized for models with a narrower tube diameter. The Standard won’t sit cleanly in these smaller-tube boats — the Small is the right fit.

Standard (34L)

Compatible: All models

The safe default. Works with Caribou, Expedition, Gnarwhal, Mule, Mage, and every other current AlpackaRaft. Two bags, one per tube side, for balanced weight distribution.

XL (64L)

Compatible: Forager, Oryx, Ranger

For models with a large-volume Cargo Fly. Roughly twice the capacity of the Standard — suited to long expeditions and the Forager’s XL Cargo Fly system. May be a snug fit in the Ranger.

Shared Specifications

All roll-top bags include a quick-release buckle for clipping to the inside of the packraft tube (some older models may not include mounting clips). Sold in a set of two across all sizes.

Packing Tips

• Distribute weight evenly between the two bags — imbalance causes the boat to lean.
• Wrap hard items (pots, stove) in clothing and position them toward the inside and upper portion of the tube — protects the fabric from abrasion in shallow sections.
• Place heavier items lower in the tube to lower the center of gravity.

Roll-Top vs Zipper-Style

Roll-top covers most scenarios. For big water or permit rivers, see the Zipper-style bag.
