Lightweight merino-blend cycling base layer for year-round riding

Designed for all conditions, including high summer, the Merino Mesh Base Layer offers high performance and exceptional comfort. It is made from a proprietary, merino-blend Rapha fabric which combines the natural qualities of merino with a lightweight mesh structure for additional ventilation and improved moisture management. The Merino Mesh Base Layer has a dropped tail for a great fit on the bike, while flatlock seams and raglan sleeves ensure comfort. Finished with a Rapha logo tab on the chest.


“There is no better base layer than this mesh wool piece which is light enough for the heat of autumn days but, thanks to the merino, adds lots of warmth after the sun sets.”
Outside Magazine

“It’s odd to find an item of clothing that performs well across the seasons, yet that’s just what we have here with the Merino Mesh.”

“I’ve found that with the right windproof jackets it works well on cold winter days, and with thinner long-sleeve jerseys it manages to work into double-figure temperatures as well. I can’t think of another base layer that does this and works across such a wide temperature range.”
Cycling Weekly 9/10

“Amongst my initial thoughts when opening the packet were about the fragility of the mesh, but it seems it holds up to the rigours of Team Sky who use it – so thats good enough for me! In use it’s holding up to daily wear nicely, no loose seams, stretching or tears – I’m pretty rough with my kit in general so I was worried about longevity with it.” 8/10

Rated 4 out of 5 by from Disco Disco Disco Have you ever wondered what it feels like to be a German man going to an underground rave in Hamburg. Well the first time your partner or friends see you in one of these you will be left in no doubt! This is not a forgiving garment. However, put it where its supposed to be (namely under a jersey) and suddenly it all makes sense. That layer of air between you and the jersey traps warmth, and this thing wicks like nothing else. I use these for winter rides and also for skiing as I find full merino tops just too heavy and clinging. My only reservation with all of these is that they are delicate garments. Use a laundry bag when washing. Detol antibacterial wash does wonders at keeping these fresh too.

Rated 5 out of 5 by from Excellent base layer This is an excellent piece of kit and sits well underneath a long-sleeve jersey or light long-sleeve softshell (e.g. Castelli Gabba or Rapha alternative). It has felt very comfortable even if perspiring under my Castelli almost luxurious feel. I am 179 cms tall and 70 kgs and went with a medium, which has a little bit of wriggle room (i.e. there is the smallest bit of loose fabric under my arms/sides of my chest and in my upper arms), but once on the bike and riding it feels like a very comfortable fit. I probably could have ordered a small, but a small may be too tight (i.e. for this garment I prefer a slightly more relaxed fit). This product is so impressive, I have bought a second one.

Rated 5 out of 5 by from Beautiful and functional -- even for the ladies My man loves this shirt and has it in both colors. We kid around that it's such a sexy shirt that it looks like cycling lingerie. Even the guys dig it. I myself have been looking for something just like this with long sleeves and high neckline. (We ladies need to protect our skin in the harsh Californian sun.) So I acquired the Medium and it fits like a glove. (In women's, I usually order a large in Rapha.) Job well done! And do make a long sleeve / high neck version for the ladies! The mesh women tanks are nice but we need more coverage.

Rated 4 out of 5 by from Very Lightweight This mesh base layer is the most lightweight base layer that I have ever owned. I prefer to ride with base layers under my jersey, even on really hot days, so this particular one is excellent for that. It's very breathable. I got the white one which is good for deflecting the hot sun off of my arms. However, I am a little disappointed with how loose the sleeves are. They don't feel like base layer sleeves. If you prefer tighter, more aerodynamic sleeves, then definitely order one size smaller than what you normally wear!

Rated 5 out of 5 by from Fabulous light weight base layer After using the short sleeve version of the merino mesh base layer, I now have a number of these in both sleeve lengths. There is no bulk to the garments, which makes It super comfortable to wear and perfect for use under close fitting jerseys,and jackets such as the Pro Team soft shell. Although the fabric is very light, the base layer really adds a touchdown of extra warmth and comfort when in use.

Rated 4 out of 5 by from Out of the box, well design and built. I purchased size Large. I'm 183cm, 83kg with an athletic build with broad shoulders and the fit is right on. On my first ride with the base layer, temperature ranged started at 8 and ended around 14C. I think the warmth of the layer is dependent on your outer jersey (ie. windproof, fleece lined, etc) but it performed on that front. The wicking of sweat when it got warmer was fantastic. I haven't used this product more than once, so I can't provide a long term review but this will be my fall/spring base layer while riding.

Rated 5 out of 5 by from Adaptive Performer This is the second base layer I've bought from Rapha, the first being the short sleeve version. After you receive the package, try it on and put it through its paces, you come to that rare, satisfying point in clothing where its .. "well, don't have to look anywhere else" Search is over. I ride daily and not like "oh going for a quick workout" like this is my core vehicle for navigating my city. Heading to the gym, rushing to uni classes I'm probably late for, etc. It's lots of humidity, stop and go, awful roads and rain. I tend towards meshes because they allow for superb airflow and keep you drier. That with the nature of merino fibers and I can really book it to class in conditions that would have me drenched in my own sweat and show up absolutely fine. it's magic. Plus they're handsome shirts. A really interesting fishscale looking mesh with a kind of dimensionality to them, so I just end up wearing them throughout the day with a light unzipped jacket. True workhorse garment.

Rated 5 out of 5 by from Best Rocky Horror Costume Ever. Warm as anything and breathes brilliantly, have been riding with just a ss jersey on top on the slip into Autumn/winter and hold heat better then any base layer I've had before, whilst not causing a slip into an over dressed sauna. Also doubles as the perfect Rocky horror costume for Halloween.

Does this have UV protection properties?

Asked by: Conrad449
Hi, this base layer will provide some UV protection but it does not have a specific SPF.

For someone in between sizes, would you recommend sizing up or down? I have a 91cm chest. Thanks.

Asked by: ThirdSunday
Hi, it is hard to advise properly as we all differ in shape and form. We would suggest that if possible both sizes are purchased to try and compare. Them simply send back the one which does not fit for a full refund. We have a free 90 day returns policy.
