Yes — Slingah™ and Daypackah™ are both sold individually, or together as the Slingah System™ at a discount versus buying separately. They're designed to work as a pair, but you don't have to own both.

It means the two bags are worth more together than apart — your Slingah docks inside your Daypackah, so switching between "carry more" and "go light" takes seconds, not a full re-pack.

840D Ballistic Cordura® N6.6 exterior, 210D Oxford lining, YKK® AquaGuard® zippers, Fidlock® magnetic hardware, Duraflex® and Woojin® hardware.

Water-resistant, not waterproof — the AquaGuard® zippers and water-repellent coating handle rain and showers fine, but don't submerge it. For prolonged exposure to heavy rain, use a rain cover.

The Slingah's strap is dialed in for medium and petite builds. If you're a bigger guy (or just want more room), grab the Hoopah™ extension strap — it clips right on and was built specifically to give larger frames a comfortable, non-cramped fit.

No — that's a system-integration feature, not a comfort one. When you unfold the Slingah to dock it inside the Daypackah, the strap automatically shortens so there's no loose strap dangling inside to tangle or snag. Worn on its own, the strap sits normally.

It's designed for non-essentials only (tissues, snacks, small odds and ends) — we deliberately kept valuables inside the zipped, more secure compartments rather than an easily-snatched external pocket.

We state 22L as the measured spec. Some owners feel it packs larger in practice, but we don't have hard data to back a bigger number, so we stick to what we've verified.

Spot clean only. Wipe the area with a damp cloth, and for tougher marks add a small amount of mild detergent (avoid bleach or harsh chemicals — they can strip the water-repellent coating). Gently work it in with a soft cloth, then wipe away any residue with a clean, damp cloth and let it air dry in the shade, away from direct sun or a dryer. We don't recommend machine washing or submerging the bag — it can affect the coating, zippers, and hardware.
