A baselayer with benefits: the high neck style we love, but with a zip-down cooling option. The Lux Side Zip is inspired by a beloved version from the past that folks still request. It starts with Classic Lux in a versatile long sleeve silhouette that's intended to fit the body without being tight nor loose; that ideal mid-layer that can go over a tank, but underneath outerwear. And it's a perfect style, really, because it's maximum Lux on your skin. Thumb holes and a pop of contrast Lux behind the neck zip, complete the style!

- classic lux (polyester / spandex)
- off-center neck zip
- contrast color neck gusset
- features thumbholes and watch windows on both sleeves
- side zip pocket
- 24" body length (size 4)

Soft and comfy

I've been buying Oiselle for almost a year now and do not have a lot of the colder weather pieces, so I have to say this is by far my favorite piece for colder temps. I wore it on a really cold run a couple of weeks ago with a vest over it and was actually really warm. Love this piece and would like it in other colors too!

Perfect PNW winter shirt

Soft, watch window, zipped neck, little zipped pocket - how can you not be in love with this shirt?! It is perfect for cold, rainy morning running. It is so comfortable and the color is gorgeous. Living the lux life!


Just got this In the mail and I love it. Will wear it for running and I love love the watch window. So soft. Haven’t washed it yet but will do and air dry.
For reference I am a size 4 generally. 36C. I got this in a size 6 and it fits loose and comfortable.

Lux is the bomb

This is my 5th long-sleeved lux top. Now that I've discovered lux, it's all I want to wear! So, so soft. Warm, but not too warm for Colorado winter workouts or for just wearing around an old drafty house. Pockets and watch/Garmin window are really nice. I'm 5'2" ~135 and got an 8. It's a little roomy, but good for layering. Sleeves are a little long because I'm a little short, but that is the only down-side of this piece.

Love the watch windows!

Love this top, it’s soft and is a good weight, but seriously - the watch window on the sleeves is the best invention for running tops since thumbholes! My husband is jealous because he can’t find a similar feature in the men’s section at our local running store.

So flattering & comfy

I love this for many reasons. It is perfect for running and can be dressed up. I wore it for one of my zoom sessions and it made me so confident, comfortable, and cozy. It got compliments from my students AND from my mom. #winning. I weight 180 and am 5'4", the 10 fits my perfectly. It's a confidence boost during runs too (:

Perfect weight and so soft

I wore this for the first time on today’s 6 mile run in 45 degree temps. It was just the right weight and I didn’t get too hot or too cold. The fabric texture is soft and didn’t run or chafe.

So soft!

Love the lux side zip! It's the perfect top when it's cool outside and you want a light layer on your run. It also looks nice enough to wear with jeans when you want something casual, but comfy to wear. I am 5'10" 150 pounds and the 8 fits well.
