Affectionately known around the Stanley HQ as the 'ShortStack', this little sucker's diminutive stature means it's got something to prove. Luckily, it makes its case boldly: leak-proof and insulated to keep drinks hot or cold for hours, Shorty here is ready for a single shot of espresso, whisky on the rocks or a perfect portion of oatmeal on the go. It ain't always the size that counts.
