Feels Great, Not Pill Resistant

"Went to pick up a pair of FKT shorts and saw that there was one of these shirts in the same color way. The pilling resistance seemed intriguing to me because the Alphaspire vest I wear mildly chews up spots on other shirts. Got the order in and I've got to say that the shirt seems designed for performance. Very breathable and soft and the seams are all as flat as possible. I quite liked the feel and running in it for the first time was great. Unfortunately, the shirt pilled in the same spots all my others do, on my upper chest. It's not ruined or anything and based on other shirts I've got, it'll still last a while despite being a little marred. Oh well, live and learn. One last thing to note - the care instructions for this shirt explicitly say to air dry, so you're not meant to throw it in the drier."

Comfy but significant pilling w Salomon trail vest

"Very comfy. No skin chafing BUT significant bilateral pilling on front of shirt after first trail run (50k). Shirt unfortunately ruined. Appreciate quick response from rabbit after email."

Disappointed - Over Promised, Under Delivered

"I recently purchased the white and the blue versions of the FastRock Tee SS. The shirt is advertised as specifically for trail running with highly durable nylon to resist abrasion and reduce pilling from packs. I wore the shirt in one race and unfortunately was left with the disappointment of a shirt that had the exact abrasion and pilling I was led to believe the shirt was resistant to. I wear one of the most popular packs amongst the trail community and when I reached out to Rabbit the response I received was that unfortunately ‘some’ packs do chew up the material and was provided a $25 gift card for a future purchase after having just spent $160 on a couple shirts that get out performed by $20 shirts off Amazon. Not the response I was expecting. Rabbit you can do better."

He loves it

"I bought this shirt for my son. He says it is his favorite shirt to run in. And that is saying a lot because he always run with no shirt. Time to get him another one ! He's going to wear it on his first ultra."

— Tracy G. (5/5)

Comfortable but…

"Very comfortable but piling still happened for me with a certain running vest."

— Bryan (2/5)

BEST

"I would agree with Brian V. the large is larger than one would expect a large to be. However, I am a 6'3 lanky build and it fits my length unbelievably perfect. Sleeve length is amazing (for my wider shoulders and longer arms) and the material quality is through the roof!!! WILL BE GETTING MANY MORE"

— Kraig G. (5/5)

It was fast to rip…

"… without getting to the race its name alludes to. After only two runs, the perforated lower back panel started to rip. Also the bonded seam / “mountain” design prevents the shirt from stretching naturally. The sizing also feels off. I normally wear a medium in all Rabbit tops, and this shirt is advertised as having a relaxed fit. Instead, it fits quite snugly around the waist. Combined with the limited stretch from the bonded seams, it wouldn’t be comfortable during an ultra. I like Rabbit's products overall, but this shirt fell short in both durability and fit. Also, Rabbit, can you please bring back the Race Pace line? These are the best for the hundos."

Fits larger than Rabbits normal tees

"Fits larger than Rabbits normal tees and is bulkier in width. Great feel and great material."
