Fine merino for all-day cycling comfort

Any experienced cyclist knows the value of a good base layer. It will keep you cool on scorching hot cols in July and warm on freezing descents in January. A good base layer helps regulate body temperature whatever the weather, transfering moisture from the skin and proving a vital aid to performance.

Rapha base layers are made from 100% merino wool and are naturally anti-bacterial and odour resistant. Wicking moisture vapour extremely quickly, they are soft on the skin and itch free.

Rapha's merino base layers come in three styles; sleeveless, short and long sleeve. All the seams have flatlock stitching so they won't chafe and are positioned behind the shoulders to avoid bag or bib straps rubbing while cycling. The base layers are close fitting and cut long at the back for a better fit on the bike.

"Base layers are incredibly important in winter to help regulate the body's temperature, but they also keep the body dry without it getting too hot. Rapha's base layer does this superbly, something that the mention of wool might normally have you doubting."
- Cycling Weekly

"There's a soft pliability to Rapha's wool that makes it a joy to wear as a layer against the skin. The wicking is outstanding. It's the best base layer I've ever worn [and] was equally pleasurable at both ends of the temperature spectrum."
- Competitive Cyclist

"Despite having so much cool Rapha clothing to choose from, my absolute favourite is the merino wool undervest. I practically live in those things. Whether it's training, sleeping or just chilling out around the house."
- Kristian House, 2009 British National Road Race Champion.

Rated 5 out of 5 by from Amazing merino layers, that go far beyond the bike Rapha merino base layers are simply amazing. They see use all year round, and not just while cycling. Canadian winters are hard and long, and I find myself wearing those base layers under my suits as often as I do under my riding gear. Some of my merino base layers date back to about 2006, and they are still going strong, and all this while having been washed together with the rest of the laundry - no special care. To echo Kristian House’s comments - as much as I enjoy and use a multiplicity of cool Rapha gear, the merino base layers are without a doubt my favourite items.

Rated 4 out of 5 by from Good so far Not as tight as an under armor base layer but still snug, with a little stretch. Overall, it seems to be pretty good. I have only worn it once but so far so good. Wore it until a tech t-shirt for a half marathon, it was great at the start of the race to help keep me warm and as the day warmed up it still was good at wicking mosture and keeping me feel cool. Kind of strange how it was good in two different climates. Looking forward to using it on the bike next.

Rated 5 out of 5 by from Wow I bought this as a base layer for cooler weather, which is just now starting to arrive, so my review will be based on fit and finish. The fabric is unreal, it's so soft. I've only worn it around the house for a few minutes underneath my long sleeve Core jersey, but I could tell my core area was getting warmer. As with all Rapha products, the fit, material selection, and construction are all top notch.

Rated 5 out of 5 by from Great Wicking I purchased this base layer over the summer and have worn it on some of the hottest days that I have ridden. I love the sleeveless cut and the merino wool wicks away seeat very well. I tide on the road and the layer does not restrict movement at all. I don't even notice that I'm wearing it, as I ride. I liked it so much, that I bought a second one! I highly recommend this layer!

Rated 4 out of 5 by from Sizing issue I bought a small size from online as my Rapha base layers fits me well with small size. However, it turns out this is slightly loose compare to the other product. I was almost thinking to take advantage the free return/exchange but at the end I just kept it as I am not sure if x-small would fit me better. I wore one time and it seems okay. It is still great product.

Rated 3 out of 5 by from Comfortable and warm I bought this a few weeks ago and worn it fir the first time today. However after wearing it once, although dirty there are two small holes on the lower back which have developed. I have no recollection of anything knocking or catching it, so this somewhat annoys me as usually every Raphael product I have bought to date has been excellent. Please advise?

Rated 5 out of 5 by from Essential, versatile kit addition . Recently did a 130km ride with changing weather conditions. Warm at the start and low down then once we started climbing it was cool and rained. No matter what happened I got what I needed. It kept me cool and took the sweat off me in the heat and kept the chill off my chest in the rain, especially on the descents. Haven't ridden without it since.

Rated 5 out of 5 by from Great wicking properties! Have done a range of ride distances in this top in some quite different conditions and this base layer has performed exceptionally well throughout. I was concerned about wearing the merino wool (itchy!) next to my skin however there were definately no adverse effects, to the point where I had forgotten I was wearing it!
