Delivering moisture management and breathable warmth, the women's Arc'teryx Rho Lightweight Crew Neck long-sleeve base layer top keeps you comfortable with a trim fit for hustling in the mountains.


  • Torrent™ lightweight fleece stretches and wicks away moisture; brushed interior elevates performance and soft comfort
  • Polygiene® treatment provides long-lasting odor control
  • Trim fit keeps the material close to the body for more effective performance but does not restrict
  • Layers easily, and articulated patterning adds freedom of movement
  • Flatlock construction improves next-to-skin comfort
  • Merrow stitch seam construction reduces seam size
  • Gusseted underarms provide mobility and comfort
  • Fitted fit—this trimmer fit, evolved from previous versions, is patterned to stay close to the body through the chest, waist, hip and thigh
  • Its low profile eliminates bulk, moves with the body and fits comfortably under insulation and mid layers
  • Contains materials that meet the bluesign® criteria
