Runbeam Short Sleeve
- Final Sale

why we made this

A sunburn after a run would really get in the way of tomorrow's motivation (and hydration). We designed this moisture-wicking shirt with a UPF of 50+ for the sun-sensitive among us and made it lightweight and breathable to make running long distances feel like a breeze.

key features

  • Swim fabric's UPF of 50+ provides the ultimate sun protection
  • four-way stretch helps this top keep its shape
  • offset seams under the arms help keep sensitive skin from chafing
  • underarm mesh venting helps you let off steam

tech specs

  • designed for: run
  • fabric(s): Swim
  • properties: four-way stretch, UPF sun protection, breathable, moisture wicking
  • fit: body-skimming
  • length: hip

Nice shirt, but poor care in shipping out! I bought this shirt along with a few other shirts and although the shirt fits well I was disappointed to receive this shirt with the sensor still on it right smack on the front of the shirt. I am disappointed to think that Lululemon would not assure for quality control and ensure that their sensors are removed from their clothing before shipping out. To me, it seems like poor customer service. For sure, they would check the shirt to make sure there is no sensor on it before shipping, no? I understand human error but this is just a bit ridiculous.

Nice and lightweight t-shirt I picked this up on sale for 24 at my local store. It's TTS, a bit on the short side which I like as my waistband from my bottoms slightly peek through so it shows off my great LLL waistbands splashed with color(s). The reason for 4 stars is the fit in the armpit area, the cut is quite short so it takes a bit of getting used to and feels a little off. This is a pretty basic T, but as mentioned, the material is great along with the shorter length (considering most LL tops are pretty long) and the little pocket is a cute feature but really isn't all that functional.

Great Shirt! Love this shirt! I got the black and wore it the first time on a 10 mile run and it was perfect! It really helped me stay cool and dry feeling better than any of my previous run shirts. No rubbing or anything either, the shirt was totally comfortable and moved well with me! I highly recommend this shirt! November 16, 2013
Be cautious of the zippy green color! There's something with the zippy green color that causes it to react and stain after coming in contact with things like lotions, underarm deodorant, perfumes, anything! The first time it happened, I immediately washed and most (not all) the funky orange-pink stains came out, but after it happened a second time, I was done. I have 2 items in the zippy green color, a free to be bra and this shirt, and it happened with both items. I won't be buying anything else bright colored from Lululemon again. Lesson learned.

Love this! I purchased this shirt because I was looking for a bright, short sleeved shirt to wear for an upcoming marathon and this one fit the mark. I wore it in the race and it was super comfortable, light and no chafing. I usually wear a 6 in lulu tops and this one felt true to size. The only thing that I didn't like about it is that it is fairly plain. I usually purchase singular color tops and I love feminine details (subtle ruffles, etc). However, this is really a plain tee. It is super functional but I'd be more likely to give it 5 stars if it had some subtle details. October 29, 2013
Discoloured! Terrible product. I have this shirt in black and I like it so I bought the lime green colour. The first time I wore it the shirt discoloured under the armpits, turning orange as soon as I started to sweat. It is completely ruined and I can't wear it as it is super obvious and ugly. I have never had stains from any deodorant product on any other clothes of mine, it is clearly this shirt, the discolouring is not a stain on the inside but is actually a change in the fabric colour.

Light and airy I scored this off the clearance rack at a local lululemon for $29, which was a great steal. I am 5'7" and always feel stuck between a size 4 and 6 for tops; however, they were already sold out of the size 6 so that made my choice easy. Luckily, the 4 fit well and hits me right at my hips. I have broad shoulders and do feel a bit of resistance when I make large movements such as jumping jacks, but for running where my arms stay at my side this shirt is perfect. I have it in green and love the brightness. I've also thrown it in the wash a few times and have not had any problems with the ink leaking. The mini pocket is a cute detail and I've been pretty happy with this product. That being said, a lot of the enjoyment comes from the discounted price tag. I would not have paid regular price for this item. October 7, 2013
Awesome top! I loved this top so much I bought three colors and wish there were more. So soft and comfortable. Not too thin but not too heavy. I usually size up to 10 but that was very large in this top. 8 is perfect. I am 5' 9" and 140 but do not like tops tight. September 21, 2013
Perfect! Returned a top I bought on line and found this in the clearance section... so glad I did. Washed it and wore it for a run last night - PERFECT! Bright, great material, no complaints :) August 27, 2013
I love the bright green and I like the way it fits I bought this in the bright green. I want to be seen by drivers when I am out running. Wore it yesterday for a 10k. Loved it, it was cool and dried out as I ran. I felt that I was decently covered. I know that drivers saw me because someone I met later on in the day told me that he had seen me running. I am 5 feet 8 inches tall and found the length to be fine. I did not feel the need to adjust it while I ran at all. It is loose fitting at the hem, but I quite liked that. I would buy another if it had been made in other bright and wild colours. August 25, 2013
