Like the first Scout, there are two big exterior pockets that run parallel to the main zipper (which has two tracks so you can close the jacket tightly or a bit looser if you want). These pockets house the Cargo Storage System, and when you zip down the inside perimeter of either pocket you reveal perforated leather for ventilation (the air comes in here and exits out vents in the rear).

This Torso Vent System moves a lot of air quite effectively. Hook-and-loop next to these vents keeps the big pockets closed securely until you want to rip into them. The Cargo Storage System has all kinds of pockets on both sides, and the right side has an elastic lanyard for keys or whatever. There are handwarmer pockets and an interior pocket as well.

Another cool ventilation feature is actually an improvement over the original Scout’s “airscoop” sleeve vents, which were found at the wrists and couldn’t be used if you wore gauntlet gloves. The new Scout has some mesh in the split front sleeve, which you can open for ventilation in hot weather thanks to two-way zippers. For cold weather there’s a snap-in, full-length Thermoliner with a Thermoneck neck warmer (that stores in the liner when not in use). The body of the jacket is 1.2-1.3mm Kwik­Dry water-resistant leather with Powerstretch leather panels for freedom of move­ment, double stitching in key areas and reflective piping in front and back. CE- approved armor is found in the elbows and shoulders, and an optional Temperfoam back pad slides into a zippered internal sleeve.

Fit, ventilation, protection and storage versatility in the Series IV are either equal or superior to my 10-year-old Scout, and the new version has a 10-year warranty.

The T450 is a stylishly designed trolley- type travel bag, equipped with wheels and an ergonomic telescopic handle for convenient walkabout use when off the bike. This new soft bag is made of a tough Cordura textile and features three separate storage compartments—a medium-sized outer one, a padded sleeve to fit a 15-inch laptop and a main storage section that’s expandable enough to hold a couple of helmets. It also has a side-mounted water bottle compartment (bottle not included) that’s a lot more useful than it appears on paper. The top of the bag is trimmed with silver reflective piping, and the supplied rain cover slips over the entire bag in a few simple seconds.

What really works for me with the T450, though, is how easily it clicks directly onto a Givi Monolock or Monokey mounting bracket. There’s a small plate located on the bottom of the bag secured by two Phillips- head screws—loosen them and slide the plate up for Monolock, down for Monokey and you’re good to go—with one key and the push of a button. Mounting brackets are sold separately if you ‘don’t already have one.

I don’t see the T450 Trolley Bag so much as a replacement or alternative for hard-shell top boxes, but more as a brilliant addition and complement to a box. Although the T450 locks securely to the mounting bracket, everything inside is vulnerable as only zippers protect my stuff from the rest of the world. Point is I might feel the need to take the bag along with me when off the bike.
