Myles Jack wears Douglas Shoulder Pads.
Douglas shoulder pads provide him with plenty of protection to fill the gap, but light enough for him to run sideline to sideline. Douglas pads have been some of the most popular in the league for years and work great for the young LB.
You can get the same shoulder pads as Devin White for $560 from Dicks or shop other Douglas options ranging from $55-$560.
