Our customers say…

Customers are consistently impressed with this RST product for its excellent quality and affordability. It's particularly praised for its comfort and snug fit without being restrictive, maintaining a perfect balance of comfort and airflow in various weather conditions. A notable feature is the moisture-wicking fabric, which keeps customers cool in summer and warm in cooler climates. Despite some minor issues with the stitching, the overall satisfaction with its performance against pricier brands makes it a favored choice.

Very tight fit.

Bought this for the temperature regulating claims. The material feels a little thicker than a I'd expected, so although it's probably a good warm base layer in winter, it's not as cooling in warmer weather than other base layers I have. I bought the largest size and I'm very slim, but it's still very skin tight (I know most base layers are) so I wouldn't want to walk around in this without my jacket on, or a T-shirt over the top, which negates using it in warm weather. Not as good as I'd expected to be honest.

Super comfortable with a high neck line so less need for a neck tube when its a bit cooler. So far ive used it as an extra layer for warmth and works really well as a lighter layer option

This has been a perfect addition for me, whether I need another layer to keep me warm or just want this to be the only thing under leathers on a hot day. Would highly recommend

Great product from RTS, makes leathers (race-suit or jacket) slip on/off easily and keeps you cool and dry.

This review is for my second, repeat purchase of this undershirt as I want a spare when my original purchase gives up the ghost - however despite multiple wears and washes (30c best), it's still looking and performing like new.

Good sizing and feels good when worn. Only tested in cold conditions so far but does a good job as a thermal base layer.

Simple and sufficient

Despite the fact that it feels like it is based on nylon, it works perfectly fine as a base layer. I used it and was satisfied with the result.

I'm usually a size medium to large but found this too tight would have to go large and extra large next time

This is my favourite base layer. It's very comfortable and quite warm, so probably best autumn through to spring. It's showing signs of wear on the chest but it does get worn very frequently.

Wore this top on its own under my leather jacket and nothing else from Norfolk to Cumbria on Daves Day and I was not only warm but actually sweating at some points during the ride. I am so impressed with it I'm going to buy another and would recommend it to anyone

I think this will shine more on the cooler days, high neck and long sleeve can “feel a bit warm” on hot days but so pleased with it.. I really like RST products
