The design is pure GSI genius. The plunger is the mug. No obtrusive rod to poke you in the eye as you drink, no grounds working their way around a flimsy screen. This is the portable coffee press perfected. A precision-engineered inner sleeve acts as a no-mess press, then becomes an additional wall of insulation to keep your coffee – or tea – hot. The copolyester construction is shatter-resistant and BPA-free, the secure top seals in the heat and helps prevent spills, a nylon-wrapped insulated sleeve adds warmth and protects your hands, and the whole thing fits neatly into your cup holder.
Incredibly clever design removes the intrusive plunger rod from classic French Press designs and replaces it with an inner mug that creates a double wall of insulation to keep your coffee or tea hot while eliminating blow-by and grit.
