On Merino Wool Beanie - Warmth without compromise

Stay warm on cold-weather runs and recovery days with the On Merino Wool Beanie. Crafted from 100% premium merino wool, this cosy running beanie combines natural temperature regulation with a tailored fit that works whether you're logging early morning kilometres or warming down post-run.

Natural Merino Warmth

Pure merino wool construction locks in heat whilst remaining breathable, preventing overheating during steady efforts in cold conditions. The soft, natural fibres feel comfortable against skin and offer temperature regulation that synthetic materials can't match—keeping you warm without the itch or bulk of traditional wool beanies.

Tailored Running Fit

Six gore stitching lines on the crown create a shaped fit that stays secure without feeling tight. Finished internal seams eliminate bulk and irritation, whilst the medium cuff and drop height allow you to adjust the fit based on conditions. At 85g, it's light enough to stuff in a pocket when you warm up mid-run.

Is the On Merino Wool Beanie right for you?

If you're running through autumn and winter months where temperatures drop enough to need head coverage, merino wool offers genuine advantages over synthetic alternatives. It suits runners who appreciate natural fibres, those prone to overheating in traditional beanies, or anyone wanting a versatile hat that transitions from training runs to everyday wear. The tailored fit particularly benefits runners who find standard beanies too loose or bulky under jacket hoods. Whether you're doing early morning tempo sessions, long weekend runs in the cold, or simply need reliable warmth for commuting to the track, this beanie handles it all.
