Phottix Stay-Put 沙袋 II 大型 10公斤

Took these outside for a portrait shoot on a breezy day and they held the softbox steady without a second thought. The 10kg weight is hefty, but the sturdy build means I don’t worry about my gear tipping over.

Outdoor shoots used to be a gamble until I started hauling this 10kg bag along—it anchors my light stands even when the breeze picks up mid-set. The fill feels dense and the handles make it easy to lug around between shots.

These things are solid and the 10kg weight is enough to keep my light stands planted even in a decent breeze. The strap is a bit stiff at first but once you work it in, they're quick to fill and move around.
