Faye's take
One of the very few genuinely single-fibre 100% alpaca ranges made at the source (Peru). Base layers and sports bras with no elastane, no synthetic blend, PFAS-free per the brand. Honest caveat: there's no third-party certification licence that fits — GOTS doesn't apply to alpaca, and no RWS/OEKO-TEX number is published — so this sits in Tier 2 as a natural-fibre-verified brand rather than a licenced Tier 1. If you're avoiding plastic fibres and want a warm/wicking natural alternative to merino, this is the cleanest option I've come across.
How they started
Arms of Andes was started by founders with a love of travel, hiking and the outdoors. Learning about the benefits of merino wool for outdoor clothing led them to ask why alpaca wool was not used in the same way, prompting them to create the brand.
