1. The Scout Uniform gives the boy a true sense of BELONGING. It submerges his self and makes him group conscious of his Patrol, his Troop, and the Boy Scout Movement.
2. It provides for true DEMOCRACY. With all boys in Uniform, the external differences between poor boys and rich boys disappear.
3. It continuously and persistently brings to the boy's mind the SCOUT IDEALS for which the Uniform stands and reminds him that he has promised to do his best.
4. It adds to the boy's ENJOYMENT of Scouting. The very design of the Uniform makes it possible for him to play the game strenuously, the way boys want to play.
5. It encourages ADVANCEMENT. A boy seeing Badges and Insignia blossoming forth upon the Uniform of a chum or member of his Patrol will want to earn them for himself.
6. It gives added opportunity for SERVICE. The Scout in Uniform is chosen for civic service projects before the Scout without one, because the Uniform itself adds to the boy's effectiveness in performing many services.
7. Earning the money with which to secure the Scout Uniform teaches a boy the invaluable lessons of THRIFT and PERSEVERANCE.
8. The ultimate acquisition of the Uniform establishes in a boy the feeling and sense of worthy OWNERSHIP, and encourages neatness and GOOD GROOMING.
9. Complete uniforming definitely establishes the Troop's IDENTITY as a link in the world-spanning Scout Movement-a realization on the part of the Patrol and of the Troop that each in turn is a part of a larger whole.
10. It influences the group consciously and unconsciously toward attaining the IDEALS expected of it in its boy activities and group behavior.
11. It creates a PRIDE on the part of each individual Scout in "our Patrol" or "our Troop," which in turn helps to establish and maintain valuable Patrol and Troop TRADITIONS.
12. It insures the PREPAREDNESS of the Patrol and Troop for participation at a moment's notice in vigorous outdoor activities, civic service, or the like. A uniformed Troop which the public can recognize immediately as a Scout Troop, will be more useful to local, state and national authorities in times of emergency.
13. It is a contributing factor to the TENURE and ADVANCEMENT record of the Troop. Complete uniforming, it has been proved, is one of the important features of Troops with a record of successfully holding their boys.
14. It guarantees the continuous GROWTH of the Troop, since the Uniform is a great incentive for the boy outside of the MOVEMENT to join.
15. Working for and earning the Uniform as a group-promoted project aids toward the development of Patrol and Troop SPIRIT.
16. The Scout Leader's Uniform makes his leadership more effective by adding to the boys' RESPECT for him as their leader.
17. It establishes the Leader in the eyes of the community as a man of AUTHORITY who has a knowledge of matters pertaining to boy welfare.
18. It aids the Leader in developing Troop SPIRIT and MORALE, by adding the correct Scouting touch to all functions of the Troop.
19. The uniformed Scout Leader sets the EXAMPLE, which is the first and most important step toward complete uniforming for his Scouts.
20. The complete uniforming of his Troop provides a feeling of PRIDE IN ACCOMPLISHMENT, a sense of success attained that unconsciously creates a fertile field for further successes in other lines connected with the running of the Troop.
21. It causes the Scout Leader to be UNSELFISH, to work as one of a team to give the benefits of a worldwide movement to the boys of his community.
22. Complete uniforming of Scout Troops appearing in public adds to the PRESTIGE of Scouting by giving people the finest possible impression of our Movement through the smartness, uniformity, neatness and alertness of its members.

Complete uniforming has proved an important feature of Troops that keep their older boys.
23. It secures and maintains public ATTENTION and keeps alive the INTEREST of the public in all Scout activities.
24. It aids in the GROWTH of the Scout Movement, because it attracts boys and helps to persuade parents to have their sons become Scouts.
25. It is a CHALLENGE to the community to recognize Scouting as an asset of great, importance for the development of its youth into a sturdy, upstanding American citizenry-a challenge which when acted upon will mean a further forward step toward Scout-ing's goal of serving more and more American boys.
The Official Uniform of the Boy Scouts of America consists of the following parts:
