REI Garage offers the Under Armour Men's UA Base 2.0 Leggings in Black for $26.73. Opt for in-store pickup to dodge the $5.99 shipping charge. That's tied with our mention from three weeks ago and the lowest price we could find by $6, outside of the mention below. They're available in sizes L to XXL.
A close price: Joe Bob Outfitters via Amazon has them in select sizes from $27.95 with free shipping for Prime members.
