I've worn this top for running and skiing. It's warm but breathable and fits like a glove, with good body length and thumb holes. #teamsweatybetty

Lovely comfortable long- sleeved gym top.

Originally posted on sweatybetty.com

This is a great basic gym top with long sleeves. Neckline is not too wide, not too tight. The top stays in place, and doesn't ride up while the stretch fabric allows easy movement.

Good fit.

Originally posted on sweatybetty.com

Yes, I recommend this

I really like this as it’s long to my waist and the sleeves are longer too- I’m tall so I get really fed up with tops that feel cropped. It’s comfy round the neck too. Good base layer for dog walking and gym in this rubbish weather.

Super top BUT......

Originally posted on sweatybetty.com

This is a super top, BUT, for what I wanted it for, it would have been too hot ! I have 3 s/s SB Athlete tops that I adore & wear are better for me.......Very rare for me to return anything SB. I would'nt wear any other make so sorry I involved returns.

More expensive than high street, but so worth it!

Originally posted on sweatybetty.com

Yes, I recommend this

It’s alright. Running top for winter. Could have got something cheaper from that big, high street sports retailer that does the same thing. But then it wouldn’t have the all important SB logo on the back to confirm I’m willing to spend more than I need to so on something that’s just for sweating in.

Top feels nice, but too tight.

Originally posted on sweatybetty.com

Nice top, but I had to return it, as it was too tight on me. I normally wear a size small, but for this top, I would need a medium.

Poor quality fabric

Originally posted on sweatybetty.com

No, I don't recommend this

I have worn the Athelete seamless long sleeve top for years and have a number of them. My old ones were made with bamboo and were super soft and fitted perfectly. The one currently made is a strange fabric which fell stiffly and stood up strangely across the top of my shoulders and the sleeves ridiculously long. I had ordered the XXS size which just hung on me. I think SB can do far better than this and wish they would bring back the soft bamboo fabric or at least something of similar quality. Could not recommend.
