Short answer: Water-repellent means the fabric carries a DWR finish that makes rain bead and roll off, but the shell wets out and water can still pass through seams, zippers and stitch holes. Waterproof means the shell is coated or laminated and the seams are sealed, so water cannot pass — and with an IPX7 airtight zipper the pack survives immersion. Most hunting packs should be water-repellent; float trips and waterfowl need waterproof.
| Water-repellent (DWR) | Waterproof (coated, sealed) | Submersible (IPX7 airtight) | |
|---|---|---|---|
| What it means | Rain beads off the face | Water cannot pass shell or seams | Sealed against temporary immersion |
| Zipper | Standard YKK coil | TPU-coated or AquaGuard zipper | IPX7 airtight and waterproof zipper |
| Seams | Sewn, not sealed | Sealed or taped at critical seams | Fully sealed, welded construction |
| River crossing or capsize | Not designed for it | Water may reach the zipper | Survives temporary immersion |
| Typical use | Day hunts, stalking | Multi-day hunts, wet climates | Float trips, waterfowl, boat access |
1. Coating type. Nylon with DWR plus PU is the value route; a DWR plus TPU bond is more durable and is what we use on quiet brushed faces. 2. Zipper class. A standard coil zip is not waterproof, a TPU-coated zip resists rain, and only IPX7 airtight survives immersion. 3. Seam treatment. Ask whether seams are sealed or taped, or only sewn. 4. Where the water gets in. Test the zipper line, the base and the strap attachment points. 5. The honest rating. Ask what the pack is rated for — rain, spray or immersion — in writing.
Our waterproof line covers all three levels. The 906-001 and 906-008 backpacks use an IPX7 airtight and waterproof zipper with TPU straps, webbing MOLLE and sealed panels, and the dry-bag programme adds 840D nylon TPU dry packs plus the 50L / 100L floating waterproof duffel. On the hunting side, nylon bodies are finished with DWR plus PU, and brushed-tricot quiet faces use a DWR with TPU bond — so a pack stays quiet and sheds weather.
