I am a very small fine wool Merino breeder and passionate about Australian product and love the wool items I have purchased from merino country. The quality and weight of tee-shirt, track pants and long johns is very good. I can only recommend anything I have bought. Dave Reid Crookwell

Absolutely brilliant, Skied Big White in Canada for 3 weeks at -5 to -18 and they were so comfortable & warm. I would recommend them to anyone just to use as pajarmas in winter here in Oz .

Perfect for Antarctica Expedition

Apart from better value for money and quality, the MC 275gsm thermals outperformed the well known 'branded technical merino' which I also took with me on a two week tour of the Antarctic Peninsula which included 12 shore landings and sea kayaking. I combined the MC275 kit as my second layer on top of a base layer merino tee and boxer shorts (in chilli red and very comfy!). Depending on the weather conditions at our landing sites I would add to this typically with puffer jacket + coastal jacket, technical pant + waterproof overpants, muckboots (with only 1 pair of merino sox), and of course gloves, hat and sunnies. This got me thought all landings bar one where we needed an extra layer!

Thermal Pack

Bought some for myself & then ordered others to be sent direct as gifts as they are so light & yet keep the body nice & warm. I suffer from not being able to handle a lot of products against my skin, however i am able to handle these 99% of the time & as per the instructions, just air & don't wash for 5 or so days. Top product when working long hours on cold nights.

Absolutely Outstanding

Just wanted to say I am so pleased with the service. The email on how to store and take care of the wool is amazing. The clothing is ABSOLUTELY out standing, especially the underwear it fits perfectly and feels amazing, I am so satisfied with it. When I put on the underwear I realized I have just discovered what superman has been wearing all these years. I have purchased similar clothing in past spending alot of money and it didn't stand to it's expectations, what I have ordered from your business is beyond my expectation. Thank you for your service and honesty, great work! Will be ordering more and spreading the word!

Excellent Product

Robert loves his thermals and his Dad (84 year old fisherman) who works on the Trawler with him said it's the warmest he has been in years… so thank you so very very much for an excellent product.
