Everything here
All 4 kids and youth
How this section is put together
All four are compression cut and all four are thermal, which means they are for the cold end of a season rather than year round wear. Two are tops, one is tights, and the sizing runs by age rather than by chest measurement.
This is the highest rated section on the site at 4.67, though it is also the smallest, so read that number for what it is.
Under the uniform
Flat seams and a close cut so nothing bunches under pads.
Cold weather only
Brushed fleece inside; too warm for a summer session.
Washing and wear
Size by height first
Compression fit means an age label is a rough guide. The chest and length columns in the chart are the ones that matter.
