If you buy Icebreaker for merino base layers that regulate temperature and resist odour, this list covers the brands that come closest — some on fibre, some on function. Smartwool is the nearest like-for-like (same VF ownership, same Denver office, cheaper socks and layers); Isadore and Café du Cycliste do merino for cyclists; Arc'teryx, Rab and Mammut are where you go when you need shells and insulation over the top. Nothing here matches Icebreaker's full farm-to-garment ZQ wool traceability, so treat the rest as complements rather than swaps.

Smartwool. Both are merino specialists, both are owned by VF Corporation, and they're run side by side from Denver. Smartwool leans harder into socks and sits a price tier lower; Icebreaker has the deeper base-layer and tee range plus ZQ-certified, farm-to-garment New Zealand wool traceability.
Yes. Smartwool and prAna are the two low-to-mid options here, and Patagonia, The North Face, Outdoor Research and Cotopaxi all sit in the same mid tier as Icebreaker. Arc'teryx, Mammut, Trew Gear and Aztech Mountain are all more expensive.
They solve different problems. Arc'teryx builds Gore-Tex hardshells, Atom insulation and climbing hardware from North Vancouver at a high price point; Icebreaker makes the merino base layer you wear under them. Many people own both.
VF Corporation, which completed its purchase in April 2018 and pairs Icebreaker with Smartwool. Jeremy Moon founded the brand in Wellington in 1995.
Smartwool most extensively, plus Isadore and Café du Cycliste in their cycling jerseys, Erin Snow in skiwear developed with The Woolmark Company, and Helly Hansen through its LIFA base-layer system.
