Women's Core Breathable Long Sleeve

The one you reach for first. Cut for the long Sunday effort and the short sharp Tuesday one, the Women's Core Breathable Long Sleeve is stripped to the parts that earn their place and nothing else — mesh placed where heat actually builds, not where it looks good.

The long sleeve uses pared-back essential construction with no visible hardware, made up in open-structure ventilated knit with visible mesh zones, finished with tonal flatlock stitching and a soft woven inner label, and given a narrow ribbed insert where the garment needs to give. Everything else is kept quiet: internal taping in a contrasting warm grey, just visible at the edges. It is cut on a women's block, shaped through the waist with a higher, softer armhole, so you get chafe-free mileage and heat that leaves as fast as it builds. No break-in period, no fuss.

• Targeted mesh venting through the high-heat zones
• Raglan sleeves for a clean overhead reach
• Thumbhole cuffs that keep the sleeve down
• Sits flat enough to layer under a shell
