The Castelli Prosecco Tech Long Sleeve Base Layer utilises a blend of advanced materials to provide effective warmth, wicking and high comfort. A polyester stretch rib knit makes up the main body, and the inclusion of Primaloft® panels at the waist and back ensures balanced insulation across the body when wearing a bib tight or bib short. Finished with a crew neck, this base layer will fit comfortably under most jerseys, even those with a low-cut collar.

If you're unfamiliar with your Castelli size, we recommend you go up one size to obtain the best fit possible. Note that you do not need to size up for jackets or vests; please select your normal jersey size.
Castelli clothing is designed for its intended use and should be comfortable when on your bike in a riding position. Your garment should be snug to provide you with moisture-wicking capabilities, as an aerodynamic aid and prevent any fabric from flapping in the wind.
If you require any advice on Castelli sizing, please do not hesitate to contact us.
A. Chest: Holding the tape horizontally, measure under your armpits with your arms relaxed at your sides, around the fullest part of your chest.
B. Waist: Holding the tape horizontally, measure around your natural waistline, across the belly button, keeping the tape a bit loose.
C. Hips: Holding the tape horizontally, measure around the largest part of your hips, keeping the feet close together.
D. Inseam: Measure from the crotch to the base of the ankle bone
Not cheap but a great baselayer for cold rather than very cold days. Usual Castelli quality and extremely comfortable fit. Mostly use on its own under a Castelli Perfetto jacket as don’t like to get too hot during a ride. For reference I wear a Medium in all the other Castelli garments I own but found a Large to be the best fit in this after returning the Medium size.
I bought this as a general use lightweight base layer for cycling, skiing and motorcycling. Fit, quality and styling spot-on from Castelli.

I believe "available for delivery" means they can ship it to you, and "available for collection" is just for click-and-collect in Sigma's stores near London. I agree that flying to the UK right now is not worth it for a single base layer, but, if you added a bike to your basket maybe? :-)
Hello, Items showing as available for collection are only in stock in our store, so could not currently be offered for delivery. Many Thanks Liam
Castelli has been at the front of cycling apparel since 1876, founded in Milan as the original maker of pro race kit. From the first cycling jerseys to today's WorldTour-proven aero garments, the brand has spent nearly 150 years putting innovation onto the backs of the fastest riders in the world.
Castelli outfitted the first organised cycling teams in Italy and has been a constant presence in the pro peloton ever since. The Scorpion logo appears on more WorldTour podiums than almost any other apparel mark.
