Poor Fit
The fit was all wrong on me. The small was too tight and the medium was baggy in the body.

Lovely long-sleeved top for the gym, great fit but decided I wasn't keen on the colour so returned for refund.

Very comfortable long sleeved top. Washes well and always looks great. Sweaty Betty clothing is created to last and out performs other brands by a mile.

Comes up small
Originally posted on sweatybetty.com
Quality top which is a lovely colour and was looking forward to wearing it until I tried it on. I’m a size 8 and usually opt for XS in Athlete seamless vest which fits perfectly. Opted for S for the long sleeve hoping for a slightly looser fit but this comes up more like an XS. It’s very clingy and not the fit I was hoping for. If you want a looser fit size up a couple of sizes in this top. Left feeling disappointed and will now probably just use as a base layer for running.

Running top

the sizing seems to be out - i’m a medium but had to buy xl. The material is slightly thicker than the previous ones and this one rides up from my hips as i’m running which is annoying. So perhaps the design is not the best. Disappointing buy, everything else i’ve bought has been fabulous.

Comes up smaller than usual

I already have this top in many colours in a size small but this one bought yesterday is much tighter. I measured it against my other ones and it’s definitely smaller. Which means I will need to return it. A shame as it’s my go to pre and post training top.

Superb quality, colour not quite as bright as pic

Bought for skiing. Product is really good feel and quality. Ordered 2 sizes, I’m a 12 and the M fitted perfectly. The only reason I haven’t given a 5 is because it’s colour (pink) is not as bright as the pic and it was the really bright pink I like.

Lovely warm top for running. Could he used as a base layer for skiing too. Sleeves are a little long but that didn't bother me at all. Rides up a little when running.

In bought this and was so excited by the lovely colour but the sizing is madness! I sized up to be safe and it’s obscenely tight, it looks like it’s painted on ! Disappointingly I will be sending this back and not buying from here in the future!

Brilliant long sleeved top, more expensive than the competition but worth every penny. Great fit, warm but not sweaty, washes well and will last for years.

Nice, versatile top

Love the colour and shape of this top, it's true to size and a really nice fitted design with long enough sleeves for me to comfortably use the thumb holes. It's a versatile piece I can wear to the gym or running and can layer easily. The only reason I'm deducting a star is I wore my running rain jacket over it and the top pilled along the zipper.

Perfect.

I love these athlete tops and have them in a range of colours now. I don’t use them for activities but as day to day wear in the cold months and double up on them when it’s really cold. Perfect.
