Wool is one of the oldest fibre types used here at Stanfield’s and one that has certainly proven it can stand the test of time.

To get the longest and most vibrant life out of your wool garments there are some additional steps to add to your normal laundry routine.

In general, we recommend washing in cold water (30°C), laying flat to dry and to reshape the layer(s). This will allow the fibres to recover to their original shape and bring out the best of the natural resilience and spring of wool. Do not bleach your wool.

Once your wool is completely dry, it can be aired out inside or outside for a fresh new start. We recommend gently folding and storing your knitted wool garments in drawers as a best practice.

Your wool can be machine dried but does run the risk of shrinking if done. We always recommend laying flat to dry whenever possible. If you choose to iron your wool, always do it at a low temperature (never exceeding 110°C). For professional dry-cleaning, dry-clean, normal cycle, any cycle other than trichloroethylene.

But what about moths? If you are storing your wool long-term and not using regularly or storing in your daily-use closet, there are precautionary steps you can take to best store your garments. Food stains and body oils can attract moths. Before long-term storage, ensure your garment is clean and always store in airtight bags or containers. You may also choose to apply a moth repellent to your garments but remember not to place them directly on the garment.

I'm a medium long in size so generally things are usually on the short side, but this underwear fits perfectly. I'll be ordering another pair thank you.

Warm and comfortable

I’m wearing them as I sit here. They are true to size, warm and comfortable. No itch. Great for the cold weather here in Labrador.
