Castelli Sanremo 2 Thermosuit review

The Castelli Sanremo 2 Thermosuit might technically be a cycling onesie but it could make a great addition to your winter wardrobe

Cycling Weekly Verdict

Castelli has blended two great items here – the Sorpasso tight and the Castelli Gabba. I like the two separately and they work well as a onesie (suit) too. Although the fabric of both upper and lower parts of the garment are stretchy, fit will be an issue for most, as it was around my lower back. If you can find the right size for you, you certainly won't be dissapointed with the Castelli Sanremo 2 Thermosuit.

    Fit isn't perfect

If you are a fan of Castelli Gabba jersey and the Sorpasso tight then maybe the Castelli Sanremo 2 Thermosuit is for you. At first I was a little sceptical – a one-piece suit for winter riding will look awful and surely fit will be compromised?

Whilst the black-on-black colour managed to avoid looking like a onesie the blue/black contrast worked best, at the very least looking like a regular long sleeve and tight. Individually the jersey and tights fit very well. The tights fit supremely well around the leg and bum, with the chamois doing an excellent job of staying in place and feeling impressively comfortable. I found them to be supremely comfortable against the skin too.

Fit will not be suited to everyone

The jersey is great around the shoulders, arms and chest. Finally, before I mention the bad points, the lack of bibs is a great idea and removes all stress areas around the shoulders.

Fit isn’t totally ideal, as expected, and I feel that those with an odd body shape might struggle with this.

The issue is around the lower back area. It feels tight and restrictive and I’m not exactly large around that area. Separately, these garments test very well but joining them together I feel isn’t totally necessary.

Blue and black colour looks great

The waistband around the front, however, works surpsringly well and makes pee stops easy, with plenty of stretch and access around the lower torso.

The light fabric works well for typical UK winter weather; you’ll feel chilly at the start but it allows you to maintain a warm temperature throughout your ride.
