Icebreaker Merino 150 Anatomica Boxers

Lightweight merino boxers that stay comfy, supportive, and stink-free from first lift to last beer.

The Icebreaker Merino 150 Anatomica Boxers are classic slim-fit boxer briefs made from Icebreaker’s Corespun merino blend, giving you everyday comfort with serious performance chops. The 150-weight fabric wraps soft merino around a durable nylon core with a touch of elastane, so you get that breathable, odour-resistant merino feel plus extra stretch and longevity. A contoured front pouch provides secure support, and flatlock seams help minimise rubbing whether you’re hiking, riding, or just clocking a long travel day. Finished with a soft elastic waistband and a low-bulk fit, they’re an easy upgrade from cotton undies and ideal for active missions or multi-day trips.

• Corespun merino blend – 83% merino, 12% nylon, 5% elastane for softness, strength, and stretch.
• Ultralight 150 fabric – Lightweight jersey works year-round and dries quickly after big days out.
• Slim, supportive fit – Close cut with a contoured pouch keeps everything in place without feeling restrictive.
• Flatlock seams – Low-profile stitching helps reduce chafe under shorts, pants, or harnesses.
• Elastic waistband – Soft brushed waistband holds firm without digging in on long missions.
• Natural odour control – Merino fibres manage moisture and smell, so they’re ideal for repeat wear on trips.
