Rally Proteinshaker

I was skeptical about the double-wall insulation keeping things cold, but after a two-hour workout my water was still icy. The handle loop on the lid makes it easy to carry between sets. Only wish the spout opened a bit wider for faster drinking during breaks.

The twist-on lid seals tight enough that I tossed it in my gym bag with ice water and not a drop leaked. Pop spout is handy for one-handed sips mid-run, though the handle loop feels a bit stiff at first. Kept things cold for a solid couple hours, which is all I really need.

The double-wall insulation actually works—my shake stayed cold through a two-hour workout, which is a win. The lid is truly leakproof, though the pop-open spout takes a bit of force to flip up mid-sip. Solid shaker for the price, just wish the handle loop were a touch bigger for my fingers.
