Christopher J. ★★★★★ Oct 22, 2026

Used this to replace a bent stay in my pack and the pre-curved shape fit the frame channel perfectly right out of the box. Slide-in was effortless and the medium 20" length was exactly what I needed.

Timothy ★★★★★ Oct 21, 2026

The curve on this 20" stay matches the frame of my Arc Zip Ultra perfectly, and it slid right into the holster without any wrestling. My pack’s back panel finally holds its shape again after months of slumping.

Joshua ★★★★★ Oct 20, 2026

Fit perfectly into my Arc Haul Ultra with zero fuss, and the pre-curved bend holds its shape even after months of packing and unpacking. The 20-inch length is spot on for my torso, and I didn’t have to bend or trim anything.
