Gate check bags are travel bags specially designed for the transportation and storage of car seats and strollers or pushchairs. Generally used for airline travel, they also provide protection from dust when in storage for the occasional user. When used for airline travel the strollers and car seats are placed in gate check bags at the departure gate before boarding. The bags protect strollers and car seats from dirt whilst in the loading or cargo bay as well as from elements such as rain or snow if left on the tarmac.
