About 16 cu ft (≈ 450 L) — typically 5–7 pairs of skis (up to ~180 cm) or 3–5 snowboards, plus duffels and boots. Is it easy to install and remove? Yes. The PowerClick quick-mount “clicks” when tight, so you know it’s secure. Two people recommended for lifting on/off. Can I open it from both sides? Yes. It features dual-side opening with the SlideLock system that indicates secure closure. Will the rear hatch clear? On many vehicles, yes. The Motion 3’s forward position improves hatch clearance—always check your rack/vehicle combo. What’s the maximum load? Up to 165 lb, but never exceed the load limits of your vehicle or roof rack system (use the lowest rating). What crossbars will it fit? Works with most aero, square, round and factory crossbars within Thule’s recommended bar-spread. Verify fit before purchase.
