Naturally wear it more often without washing.
Wool merino is the most natural odour resistant fibre. You can wear it several times before washing it.
The merino wool fibres absorb bacteria, avoiding them from reproducing. So, naturally, your socks and garments will have less unpleasant smells.
Test it yourself. But don’t fool yourself: to have the benefits of merino wool make sure you buy products with a high percentage of wool content (without “enemy” synthetic mixtures).
For garments, we recommend at least 75% of wool and for socks at least 60%.
