Featuring standout visibility cues of fluorescence, reflectivity and pattern, The Two Tone Siren is now somehow even more terrifyingly conspicuous with the addition of long sleeves. It's just lousy with reflective squares on the back and shoulders for when it gets dark, and hewn from Italian Giotherm™ fabric, a bit thicker and warmer with a smooth exterior and warm fleecey interior for when your riding takes you places that get under 65° F (18°C). The Two Tone Siren long sleeve jersey is an outstanding choice for any time you need to be seen among traffic and it keeps the rider functionally warm well down to about 40° (4°C). Features a full-length zipper for versatility, and three roomy pockets out back for your wedge of panforte, pack of neopolitan playing cards and tin of kippered herring (or whatever, really). Designed and fabricated in California USA.
