We're planning two major trips this year, one locally and one internationally. Both places we will be renting a car and driving around and would need to take our stroller and car seat. We will be gate checking both of them bc we have a travel system. In worried about them damaging. We have a britax travel system and can buy the covers of both but it's like $30 each. There's the cheaper generic option available for like $15. Does these work just as well?
