Constructed from lightweight, sweat-wicking fabric with high-stretch mobility, the Interval Shirt is equally at home in max-effort conditioning, tough strength days, and miles on the road. Bonded

Really good minus inconsistencies around the collar
Fits well and performs great in the gym. Prefer these over shirts from a brand that starts with Lu. Only problem is that some of the shirts the neck area is bunched up or has this weird bump next to it.

Best workout gear ever
This tee wicks away sweat quickly and looks great. What more can you ask for feeling good and looking good during and after workouts?

Fits great, durable material
I have been wearing the interval shirt option for a while. It has a great fit and holds up well. I work out about 6 days a week. I have not had any issues. Very happy with my purchase.
