The nice thing about handlebar bags is that they relieve you from having to rely on jersey pockets or backpacks for day trips and touring. This very nicely designed one from Topo easily attaches to most every handlebar via Velcro straps and features a removable shoulder strap for off bike use. Ergonomically shaped and spacious, it secures all your daily essentials in a fully waterproof compartment so you will never have to worry about water bottle spills or getting caught in the rain. Exterior daisy chain webbing allows you to attach bike lights while durable, recycled nylon resists abrasion from anything you may run into on the trails.
