Wore my new Alpha Ros jacket for the first time today. Despite temp in low 40s Fahrenheit, I felt comfortably warm after just a few minutes with just a merino wool blend base layer. And, never too sweaty either. Total comfort - truly amazing and impressive. The design is awesome and this jacket is worth the price. Submitted on 15 November 2019 by David Diskin
Got this jacket last week. Nice looking jacket feels like you’re wearing a jersey. Definitely a great purchase Submitted on 13 November 2019 by DocNasty
I have used an Esspresso jacket through 2 winter seasons and am completely impressed. It is warm, windproof and comfortable. It layers pretty well and simply works. I also have - this year - purchased the Alpha Ros jacket. Also very nice. I compared them on the same ride on a chilly day with identical layering. Both windproof, comfortable and good looking. I think I would give the Espresso the edge on warmth with one light shirt underneath. I think the Alpha Ros will layer better, and is claimed to be better against rain. One other point: As is most normal with Castelli, order one size larger, except with the Alpha Ros. It turned out I needed 2 sizes larger. Submitted on 21 September 2019 by Ralph
I'm 6ft, 69kg and I get cold very easily. Prior to getting my Alpha RoS jacket I didn't look forward to going out if it was cold and/or raining because i'd get really uncomfortable because the only way i could keep warm was multiple layers and a rain jacket, which meant i'd boil on climbs and then the sweat would chill me because the breathability wasn't there. Enter the Alpha RoS. I visited mum in Tavistock and went for a 4 hour ride over Dartmoor. The temp was 10c the wind was howling at 30-40mph, the very light rain turned into sideways medium weight rain. Although not that cold, when you're getting wet and getting blasted with wind you get cold very quickly...not with the Alpha RoS you don't - at the start of the ride down in the valley I was overheating because i was wearing my Castelli Flanders base layer, so i took that off and just wore the jacket on bare skin, which was comfortable. The jacket is incredible adjustable in the thermal protection - unzip the inner thermal layer and zip the outer, zip the inner and unzip the outer, unzip or zip both - all with gloves hands and in seconds so at the bottom of a climb you unzip and at the top you zip up - it's PERFECT. As the weather deteriorated I zipped up and after I stopped at Princetown for lunch my core temp must've dropped before I had to put the base layer back on.. The last leg back to Tavistock was brutal - crosswind so strong that I was in danger of getting blown across to the other lane, the rain was horizontal and it was cold. I however, rode in total comfort and enjoyed the sheer rugged landscape and the fact that i was out there when very few others were. If it's below 10c i'm wearing my Alpha RoS period. Thus far i've ridden it down to 2c and its' clear that it can handle much more, particularly when pairing it with the Flanders top. I have a non-thermal base layer and i'm totally comfortable in my Alpha at 4c. It breaths well and it handles rain brilliantly because although i'd not 100% waterproof it is "real world waterproof", acknowledging that you're going to get wet from sweat in a fully waterproof jacket, so it focusses on breathability so rid you of moisture (rain or sweat). I combine it with the Nano Flex 2 bib tights, Tempesta gloves and the aforementioned Flanders base layer and basically the weather is now pretty much irrelevant to me, which has greatly increased my enjoyment of riding in the winter. For someone who gets cold very easily and isn't very 'tough' - this is a miracle level piece of clothing. Before i bought it I thought it was very overpriced. Now i wouldn't be without it - you get what you pay for. Submitted on 15 December 2018 by Jimbo
Awesome jacket does exactly what is says on the label. However how does a £260.00 jacket not receive 5 out of 5 on all attributes when it is advertised as the PERFECT jacket.. Submitted on 13 January 2018 by JMB
I've been extremely pleased with the Alpha Ros Jacket. Winter training is sub 32 F degree weather is made simple knowing you'll keep warm and dry. I picked up the bright orange variant knowing it would contrast well in snowy conditions. Sizing and fit remain consistent with Castelli's Euro fit and is not bulky at all. This a very versatile piece, the key is vary your base layers based on the temperature you're riding in. I'll use a sleeveless summer base layer for warmer days or a heavy wool baselayer for the coldest of days. Overall, this is my go to jacket during the cold winter months, and I think Castelli has done an excellent job on this piece. Submitted on 03 January 2018 by Renzo
I bought this jacket for vinter / autumn period, as here in Denmark the weather can be like rainy and temp around + 3 Celsius which makes it feel really cold. So the jacket arrived and i looked at it thinking this is very thin can it do anything in the cold ! Well turns out its really really awesome jacket and it holds out the rain perfect. Even during my daily commuting to work where i also have a backpack on and i normally get wet on my back... thats not happening. Dont know how thats made possible. So even though the price is high, the quality and purpose is simply stunning. Submitted on 10 December 2017 by Flemming Denmark
Coupe ajustée, très agréable à porter ! Isole parfaitement du vent. C’est un vrai plaisir de rouler avec cette veste. Submitted on 20 November 2017 by Serge
I wore this jacket today and I must say that I was impressed. When I started my ride it was -1*C. I wore this jacket, a long sleeved “early winter” base layer from another brand (which we won’t mention) and a bibtight with frontal wind protection. Paired with a mid weight glove and Castelli’s Toe Thingy and Castelli Merino wool socks with a very light head beanie and I was perfectly comfortable for my 2hr ride. I even unzipped for some of the climbs. The Gore wind protection prevents any of the cooling effects from evaporation and the jacket feels very breathable. I normally wear a size large in Castelli jerseys but with this jacket, I ordered an XL and fits perfectly. For reference I’m 5’-10”; 185lbs. and built a bit square with a slightly shorter legs(31”) inseam. It’s beautifully crafted and worth the price of cold weather admission.

I purchased this jacket specifically to ride in temps below 32 degrees. Got to try it out in a morning that was exactly 32 degrees. At first I was cold, but after about 15 minutes of moderate pedaling, I warmed up to a comfortable operating temp. The jacket is supposedly rated for temps between 23-50 degrees. I don't think I could ride much less than 32 degrees without another layer. To give some context, my base layer was an Under Armour ColdGear Evo Long Sleeve Compression Mock. I also have the Senza 2 jacket. In comparing the two, the Senza 2 is definitely more bulky, but feels warmer than the Alpha ROS. The Alpha ROS also has many more sewn parts, so I'm assuming the Senza 2 will hold up better from seams separation since it has fewer sewn parts. The Senza 2 feels warmer and doesn't feel as form fitting as the Alpha ROS. The Alpha ROS fits closer to a race fit than a casual fit. Overall, for a more casual ride or commuting to work, I'll stick with my Senza 2. For longer weekend or training rides, the Alpha ROS should work well. Submitted on 10 November 2017 by Jason T
This product is amazing and so versatile. By un-zipping the outside layer it still keeps you warm and your body can breath when climbing. Afterwards you can attack the descent without shivering. It feels just like the extra piece of skin you always searched for your winter rides. Submitted on 10 November 2017 by Igor
If you ride in total winter conditions, this is the jacket. Kept me warm in low 20f. Highly recommended! (Reviewed by a Castelli employee. Proud of this product) Submitted on 25 October 2017 by Sam
