Description

Build Your Winter Base

The Castelli Men's Flanders Warm Long Sleeve Baselayer features a SottoZero fleece interior that insulates against low winter and spring temperatures while also wicking moisture and having an incredibly soft feel against the skin.

Mesh inserts at the underarms improve airflow, and the stretchy fit with flatlock seams means it layers perfectly underneath a jersey or jacket without hindering mobility or causing irritation. Flat hem construction lets it tuck securely into cycling bottoms without creeping up during the course of riding.

Features:

  • Material: SottoZero fleece (100% polyester)
  • Insulation: midweight
  • Form-fitted
  • Mesh inserts in underarm
  • Available in Grey or Black
  • Sizes: S-2XL

  • Note: Castelli tops and bottoms are designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.

    Very Comfortable, Moderate Warmth
    by Anonymous

    Fits well, I don't notice it's on. While I don't feel it is quite as warm as other reviews have stated, it is definitely beneficial. The underarm venting is quite effective, maybe a touch too effective.

    Best Baselayer I Own

    Great base layer that works well from 30s to 50s. I am 6'-1" and 150 lbs. The large size fits like a glove. Highly recommended.

    Great baselayer for cold rides

    Form fitting and well made. I like the ventilation at the arm pit area. I wish the back was of a thinner material as that area gets less wind. I use it for cold days in the 30's with a fleece jacket and no jersey. By the end of a spirited ride my jacket is half open and I'm comfortable. Size wise I am 5'7" and 146 lbs and wear a medium which is very form fitting. When on sale I will buy a large, so you may want to size up.

    Great cold weather baselayer!

    This is a great cold weather baselayer. I use this kit on all my cold weather rides. It keeps me warm and it really does wick moisture away from my skin to continually keep me warm. I am a heavy sweater so my other long sleeve baselayers tend to get soaked with sweat which then starts to cool me off in cold weather, not this long sleeve baselayer. It does have an incredibly soft feel, the product description is very accurate. I loved this baselayer so much that I bought a second one.

    This base layer is great. Keeps me warm here (So CA) riding in temps in the 40s. Be aware that it runs small. I am 6�2� and 190 lbs and ordered an XL. It fits tight and I wish it was a bit longer. I have long arms (36� long) and the sleeves fit fine.

    Well fitting, soft and comfortable. Follow the mfr instructions and don't put in the dryer like another reviewer did!

    I'm 6'3" 195 lbs. 32" waist with a swimmer build, 44 chest. The base layer is a form fitting trim up, so no big bunches of fabric plus it is long enough to not be short to your waist. The XL fits me perfect, the sleeves nice and long plus the low cut mock turtle neck doesn't get in the way of tall collared jackets or jerseys.

    Just right for a single layer under a long sleeve jersey in 50 degree F weather or add a midlayer vest as the temp drops.

    Note, read the care instruction tags for your garment if you want it to last a long time,

    DO NOT DRY IN THE DRIER! They will tell you to not put in the dryer. It dries really fast just hanging, I washed it at noon after a ride and it was dry by the next morning for another ride. I air dry all my cycle gear expect my socks.

    Great baselayer for colder temps!

    This Castelli Flanders baselayer was great for cycling in the colder temperatures around here. I used this with a short sleeved jersey and and LG insulated jacket and was plenty warm down to 38 degrees, assuming the usual accessories for warmth. It's comfortable against the skin and isn't overly constrictive for fit, but definitely form fitting like most of the Castelli gear.

    Really great quality and fit. Perfect for my needs.
    by WES

    Many base layers are skintight and uncomfortable. Although this is appropriately tight, it does not squeeze to the point of discomfort, and actually fits perfectly. Functionally, it provides just the right amount of warmth.

    Fantastic Undergarment
    by Oakland Rider
    Cycling Enthusiast
    Oakland CA

    I really like this undergarment. It is absolutely the best in temperatures from around 35 to 55 degrees when I wear I long sleeve jersey over it. This undergarment really helps to keep me warm and yet not too warm during long endurance events. I recently road a long Brevet and temperatures got down to 35 degrees as the day wore on and this was just perfect for those conditions.

    Great tight fit. Order one size larger than usual for Castelli wear. Soft warm material, between a quality cotton and fleece feel. Use it for a base layer under a regular Jersey on those chilly mornings. It is pricey but this is another Castelli product that did not dissapoint.

    This is comfortable for winter rides, once it is in place.

    So far the shirt has not ripped, nor my ears been torn off,

    but those seem possible every time it is put on or removed.

    Size large shirt, 7 hat size. Maybe Italians have very small heads.
