People want to wear clothes that are functional and fashionable whether they are working or playing. Sometimes there is very little time to go from work to play or vice versa, so a doggo hooded sweatshirt can be a great compliment to your wardrobe.
Certainly you might wear less of these items during summer days in warm places like Southern California or Florida, but even there, these tops can be quite useful and convenient when the nights cool off. This article of clothing is also highly functional because it cleans easily and can be tossed in the back of your car or trunk for access when you need it.
One of the reasons hooded sweatshirts are so popular at work is because they keep people warm and protect skin whether people are working inside or outside. Those who work in warehouses operating forklifts can throw on a sweatshirt and stay warm while they cruise in and out of coolers and freezers with pallets for frozen food, for example.
These tops make great layering items so people who work outside can wear a thermal undershirt, a t-shirt, and cover all that with a sweatshirt for added warmth. If a sweatshirt gets too warm, people can just take it off and wrap it around their waists or store it somewhere convenient until it becomes necessary again.
