Arc’Teryx RHO LT Base Layer Review
Matt’s Specs: Sizing Info
Fit: The Arc’Teryx RHO LT has a pretty standard fit for a base layer. It is tight and form fitting, but it does feel true to size. The arms are articulated and underarms are gusted for a better fit.
Features: The Arc’Teryx RHO LT has a moisture wicking Torrent fabric that is going to help with thermal regulation. The RHO LT also has a Polygiene fabric that resists odors. It is a pullover with a ¼ zip, and it does have a small chest pocket for personal items.
Best Uses: The Arc’Teryx RHO LT is really designed to be a base layer. This would be good under a technical shell or under your insulating mid-layer for extra warmth. It is meant to keep you dry and regulate body temperature well.
