Ella ★★★★★ Oct 14, 2026

The 3D welded bottom on these actually holds up — no leaks after a month of squeezing them into a too-small pack pocket. The soft material collapses down flat once empty, which saves a ton of room.

Brian V. ★★★★★ Oct 13, 2026

These fit perfectly in my vest's larger pockets without any struggle, and the pliable material means they don't dig into my chest on long runs. The wider shape holds 500ml comfortably and I've had zero leaks so far.

Robert ★★★★★ Sep 15, 2026

The wider shape actually stays put in my vest pocket instead of folding over like my old ones. The 3D welded bottom means no leaking in my pack, and the soft material squeezes down as I drink. Two for the price made it an easy buy.
