Kevin Y. ★★★★★

Finally got around to replacing the worn-out stay in my pack, and this pre-curved one slid right into the holster without any wrestling. The medium 20" is exactly the right length, and my pack’s frame feels solid again. No more floppy sag on the trail.

Lily ★★★★★

My pack’s frame was sagging for months, and these 20-inch stays brought the structure right back. The pre-curved shape matches the original perfectly, so it was a true drop-in swap with no bending or fiddling.

Mia M. ★★★★★

Finally got these for my old pack and they're a perfect fit. The pre-curved shape really helps the frame sit right against my back, even when loading up heavy gear.
