Bike Packing Toptube Frame Pack - 4 Liter Dark Sand

Ortlieb's 4-Liter Dark Sand Bike Packing Toptube Frame Pack is a brilliant choice. It lets you use your bike frame's main triangle for storage while still keeping space for your water bottle. This pack is waterproof to IP67 standard when the zipper is fully closed, so your gear stays dry even in the harshest conditions, like during river crossings. It features waterproof fabric seams and a zipper up to IP67 standards. You can easily attach it to the top tube and seat tube with Velcro straps. Its dimensions are 19.7' L x 5.1' H x 2.4' W.

Using this Ortlieb toptube frame pack is easy. First, find a suitable spot on your bike's top tube and seat tube. Then, use the Velcro straps to firmly attach the pack. Open the waterproof zipper to put your items inside. Make sure to close the zipper completely to keep your gear dry. When using it during wet conditions, like river crossings, don't worry as it's designed to withstand water. For maintenance, clean it with a mild soap and water solution after each use. Store it in a dry place when not in use to prevent any mold or mildew growth. Avoid sharp objects that could tear the fabric. Also, check the Velcro straps regularly to ensure they're still sticky enough for a secure attachment.
