p>Get ready for your next bikepacking adventure! As a key item in your bikepacking setup, the ORTLIEB Seat-Pack comes with Velcro straps to enable convenient and secure mounting to your seat stem. Projecting backwards from the seat stem, your Seat-Pack also serves as a rear fender. The spacious, waterproof Seat-Pack keeps its contents (e.g. an extra set of clothes) safe and dry. Depending on how long you plan to be away and your Seat-Pack model, you can conveniently adjust the volume of your pack from 8 to 16.5 liters or from 7 to 11 liters by adjusting the roll closures on the sides. An additional valve allows you to quickly and easily compress your soft gear for a more compact fit. Your Seat-Pack also serves as a replacement backpack when youre out on a day trip, no matter whether you ride a hybrid bike, a mountain bike, a road bike or an electric mountain bike. The Seat-Pack is available in two sizes./p>\np>Thanks to its elastic drawstrings on the top, the 16.5-liter model offers additional space for items you need to be able to access quickly. This model needs only 15 centimeters of space on your seat stem./p>\np>The smaller of the two models needs only six centimeters on your seat stem. Thats why the more compact model is ideal for smaller frame sizes, full suspension bikes and adjustable seat stems./p>\np class=”detailhead”>FURTHER FEATURES:/p>\np>+ Reinforced fabric at all points of contact to the seatbr>+ Vertical daisy chain for rear lightbr>+ Also suitable for carbon seat stemsbr>+ Lightweight designbr>+ Four 3M Scotchlite reflectors available for full extension/p>\np>/p>\ntable id=”product-attribute-specs-table” class=”data table additional-attributes” style=”width: 99.8065%;”>\ntbody>\ntr class=”material”>\nth class=”col label” style=”width: 31.005%;” scope=”row”>MATERIAL/th>\ntd class=”col data” style=”width: 69.0342%;” data-th=”material”>PS21R/td>\n/tr>\ntr class=”bag type”>\nth class=”col label” style=”width: 31.005%;” scope=”row”>BAG TYPE/th>\ntd class=”col data” style=”width: 69.0342%;” data-th=”bag type”>single/td>\n/tr>\ntr class=”adapter”>\nth class=”col label” style=”width: 31.005%;” scope=”row”>ADAPTER/th>\ntd class=”col data” style=”width: 69.0342%;” data-th=”adapter”>-/td>\n/tr>\ntr class=”weight”>\nth class=”col label” style=”width: 31.005%;” scope=”row”>WEIGHT/th>\ntd class=”col data” style=”width: 69.0342%;” data-th=”weight”>\np>456 g | 16.1 oz/p>\np>625 g | 22 oz/p>\n/td>\n/tr>\ntr class=”height”>\nth class=”col label” style=”width: 31.005%;” scope=”row”>HEIGHT/th>\ntd class=”col data” style=”width: 69.0342%;” data-th=”height”>\np>30 cm | 11 inch/p>\np>28 cm | 11 inch/p>\n/td>\n/tr>\ntr class=”width”>\nth class=”col label” style=”width: 31.005%;” scope=”row”>WIDTH/th>\ntd class=”col data” style=”width: 69.0342%;” data-th=”width”>\np>64 cm | 25 inch/p>\np>48 cm | 18.9 inch/p>\n/td>\n/tr>\ntr class=”depth”>\nth class=”col label” style=”width: 31.005%;” scope=”row”>DEPTH/th>\ntd class=”col data” style=”width: 69.0342%;” data-th=”depth”>\np>/p>\n22 cm | 8 inch\np>/p>\n/td>\n/tr>\ntr class=”volume”>\nth class=”col label” style=”width: 31.005%;” scope=”row”>VOLUME/th>\ntd class=”col data” style=”width: 69.0342%;” data-th=”volume”>\np>16.5 L | 1006.9 cu inch/p>\np>13 L | 793 cu.inch/p>\n/td>\n/tr>\n/tbody>\n/table>
