Summit Grid vs Microchill vs Polartec High Loft

Summit Grid is the breathable, active-midlayer pick — its grid construction dumps heat while you move and packs light under a shell. Microchill is the everyday casual fleece, lighter and cheaper; Polartec High Loft is the warmest of the three for static cold. If you're building a layering system for hiking and climbing, Summit Grid under a Threshold or Stretch Ozonic shell covers most conditions. Fit runs true to size with room for a base layer. Care is easy: machine wash cold and hang dry to keep the grid fabric performing.
