We're thrilled to bring the new Flow fabric to life in this beautiful long sleeve. Don't let its lightness fool you; it's ready to work hard in any workout, on any run. Wear testers love wearing this layer, even in warmer climates, because you can forget it's there. The 2-knit texture wicks away moisture like a champ, much like our always-popular Flyout Collection. Plus, we added the details athletes know and love: our unique watch window design, plus thumb holes. A contrast stripe trim at the neck and cuffs offers an appealing design element, and the whole garment just flows.

So breathable!

This is a pretty phenomenal textile! It’s really breathable, unbelievably comfy, and durable for its weight. This is my favorite of the ultra light textiles Oiselle has made!

Light as air

This running top is part of my first Oiselle purchase, and it did not disappoint. It is lighter and looser than I imagined, but in a good way, like top notch long underwear. I am an athletically built middle-aged mom - 5’1” and a small or extra small in most clothes, just for reference, and the size small in this Flow Long Sleeve allows me to layer both under and over it for cold New England winter runs. I also reach for it when skiing and snow shoeing. No doubt when it is my only long layer, I will enjoy the watch hole - my watch fits in it just fine. Thanks for a great product!

Over-priced tissue paper

I bought the yellow version of this shirt and it is embarrassingly sheer. It also runs small. At least a full size small. This shirt is way too thin to be of any use in the cold. And it's too tight and clingy to be comfortable in the heat. With how sheer it is, I don't think it would protect agaisnt the sun either. I'm not sure what the point of this shirt is. I'm really disappointed that I paid full price. Although I'd be disappointed with this at almost any price. I do not recommend this shirt. Also, lol at wearing this on the trail. It will get ripped to shreds in no time. It catches on EVERYTHING and causes the material to pull. I don't know how this shirt got such good reviews.

My go to runner

This is the 3rd gen Flow shirt for me. The fabric changes a bit each time, assume because they’re so fragile. Perfect base layer for running here in the mtns.

I do shred the thumb holes and elbows(?) pretty quickly. New/different material for the cuffs so maybe will hold up better. I just cut the sleeves & turn into Ts when they get too frayed. While I’d love for these to last longer, I’ll keep buying because they’re such perfect running weight for me!

New Running Staple

I've been super impressed with the Flow Long Sleeve! I love the Flyout Hoverfit Long Sleeve and the Flow has definitely taken a seat as another LS staple. It is similar to the Flyout in that it is very breathable, but I'd say it's even breezier and I could wear this into warmer temps than I would with the Flyout, as far as Long Sleeve's go. It has a super silky feel to it and I love the wide band on the bottom hem of the shirt. I wear a size 2 in the Flyout LS and got the Flow LS in a Size S. I think it feels a little delicate, so I just make sure to wash it with similar items and no zippers or velcro!

Beautiful, breezy and no chafing!

The most gorgeous functional top for long runs! There isn’t anything quite like it. It’s like running in just a sports bra but better. I just came how from running in it and ordered 2 more. Couldn’t resist the temptation.

Perfect base layer - and main layer

As a heavy sweater and person who runs hot, this is a great layer for cool and cold days. It's comfortable in the 40s, and it works well as a base layer in cold days to keep me warm enough without overheating. It looks elegant, and it's so soft!

amazing lightweight long sleeve

This is one of the softest and most comfortable shirts I own. keeps me covered and a good layer when cold, and I don't overheat. It is SO SOFT. Cannot recommend this enough. I have the orange/navy, which looks almost bright pink in certain light.
