Castelli Prosecco Short Sleeve Base Layer - SS18
This midweight base layer is made for cool conditions or even high-intensity cold-weather rides where wicking moisture away from your skin is the first goal. The hydrophilic Prosecco treatment spreads the moisture out over a larger area for quicker evaporation. Castelli use two different weights of fabric, with the thinner layer used where it will be covered by your shorts/tights or bib straps so that you don’t have too much insulation where you don’t need it.
  • Excellent moisture management in medium weight for cool conditions
  • Prosecco 1st Layer 100% polyester main body fabric
  • Prosecco Micro fabric where less warmth is needed
  • Anatomical cut
  • Flat stitching at hem
  • Weight:109g


This keeps me warm on those cooler days. Nice and light
Very advanced base layer. quite warm, good for spring and fall. I am 177 cm and 74kg and size L is just fine. As always Castelli runs small.
Very good base layer for fall conditions. Excellent moisture management and just enough heat protection. I use it between 5-10 Celsius.
Perfect fit, is a little bit warmer than I expected, too warm for temperatures above 15°C - maybe only with light summer jersey
Very good quality. CASTELLI !!! For 1.88 m and 87 kg size XL is fine.
A very good base layer. Drain moisture perfectly out of the body maintain warm and dry. I recommend.
Great product, fitted as expected (went for a large - I`d normally wear a medium).
Perfect cycling cut/fit as per usual for Castelli (be careful with sizing, as per usual with Castelli too). The Prosecco is significantly warm, slotting in between a winter-only merino layer and the much lighter Castelli Pro Issue. My only gripe would be the tight collar which could do with a bit more stretch, hence my 4 stars rather than 5. Merlin was the best price on the web too, also as per usual.
Top class base layer! After years of trying others, I finally got around to getting a s/s and l/s Prosecco. Fabric feels so soft to the skin. Wicking is superb. Looks good too with the red highlight to collar. Size-wise I didn`t do the usual size up 1 size as a base layer should be tight fitting.
High quality as expected. I am just over 5ft 8in and 133lbs and Medium fitted comfortably.
Not much to say about these quality bits of clothing - warm enough, snug fit and good wicking. Like them a lot.
Excellent base layer for typical UK conditions, under a standard jersey in the summer or a windproof in spring and autumn. Typical Castelli fit - size up if you usually have to.
Unlike other Castelli gear I opted for my normal size.....fitted well. IMHO no need to upsize with this base layer...its meant to be tight!
Usual Castelli quality and great anatomic fit. Don't size up on this stay true to the chart, you want this as fitted as possible as it is a base layer. I am 1.81m 74kg and M is perfect.
A perfect fit, as usual with Castelli go a size up. I take a medium in everything but in Castelli a large.
Went great under my new short sleeve Gabba. Would buy another of these especially with spring approaching.
This base layer t-shirt does exactly what it should do, keeps you warm in the colder weather, the medium is a nice fit for me, a normal 32 inch waist, the black one looks good.
Very good base layer works well. The sizes are quite small - I'm fairly small and needed a large which is still a skin fit + fairly short - just tucks into my shorts/leggings. Will order another soon. Like the black colour for a change.
