Lezyne addresses some of the common missteps made by many other saddle bag manufacturers. For example, the strap that secures the bag to the saddle rail is wider, semi elastic and slightly thicker than other straps. This provides a solid connection to the saddle and keeps the bag from floating and rattling. The zipper is robust and will not rip or break apart if you over stuff the bag. Lastly, the profile of the bag is narrow and drops down a bit lower than most other packs. This means it tucks nice and tight under the saddle and you will never sense it is there when you riding.
The Micro Caddy is constructed of durable woven nylon fabrics which will stand up to much abuse in the field. Reflective logo and stripes help keep you visible. There is an easily accessible, external multi-tool compartment which allows for quick adjustments. Inside are two small compartments, one for tire levers and the other for CO2 cartridge. The Micro Caddy Medium has a 0.40L capacity.
