## Customer feedback

Customer feedback highlights fit, warmth, functionality and value, with reported uses including wearing the set under sweatpants, backpacking in cold weather and sleeping as temperatures fall. These experiences are relevant to its stated fleece-lined, stretch base-layer design, but do not establish a specific warmth rating or performance in every condition. The overall rating distribution is mostly five- and four-star, with a smaller share of lower ratings, so experiences are not uniformly positive.
