Merino Long Johns / Leggings

Made in New Zealand, thick and oh so warm,so much better than Chinese made ice breaker luv them awesome

Merino Long Johns / Leggings

I'm Australian and I ordered long johns to travel to Canberra. I expected snug fitting so I could wear under jeans. Although these are snug around my hips - the legs are baggy and loose, so cannot be worn underneath anything (except maybe ski pants). Which defeats the purpose as a base layer. I just use them as Leggings now.

Merino Long Johns / Leggings

My apologies I am too shy to prance around on camera in the items. But I love them. They are warm and not itchy as I have sensitive skin. I wear them every day. I stay warm all day. Best items I have ever purchased and will continue to do so. Thank you

Merino Long Johns / Leggings

Legs length is way too long on the small size. The option of a short or regular length would be great. These are definitely long length.

Merino Long Johns / Leggings

I live in the MacKenzie country and have to have the merino long johns and merino long sleeved top every day to keep warm. They are a must and they perform very well. The fit is great, the breathability is great, the warmth is superb and I would tripl e my order for next year if I could

Merino Long Johns / Leggings

Love my new merino tights, so comfy, fit perfectly, lovely and soft and warm, very happy with my purchase.

Merino Long Johns / Leggings

Really good thickness and quality, just wish they had a wider elastic waist band as it Dan get uncomfortable when layering for winter. Overall very pleased.

Merino Long Johns / Leggings

It’s too big and I’m not sure how to return to swap for smaller size

Previously owned brass monkey merino, good to see quality remains the same. Would be nice to have leggings in short/standard length particularly for women.

Merino Long Johns / Leggings

Firstly my name is Jude and I bought the merinos for myself. I am pleased with my camisoles and leggings which kept me warm on those cold winter mornings watching my grandson play soccer! I returned the two long sleeved merinos as forgot I had some in the drawer. Many thanks for the refund. Cheers Jude

Merino Long Johns / Leggings

Well, your tights work a treat. I like that they're 100% merino and they are a great weight. Not too heavy nor too lightweight stretchy. They really are pleasant to wear and comfortably warm.

Merino Long Johns / Leggings

Love these tights, so warm, sizing pretty good, a fraction tight at the waist & a little long for my short legs. I’m 159cm.

Merino Long Johns / Leggings

The Perfect garment. Excellent merino fabric and perfect fit. Bought 3 sets Brass Monkey long Johns. Then bought some for my granddaughter who was equally pleased . I have a merino wool business so am a good judge of merino quality !!

Merino Long Johns / Leggings

Living in the central plateau, these are incredibly comfortable, thin and very warm. I don't notice them under my casual trousers. Highly recommend 👌

Merino Long Johns / Leggings

Product arrived quickly, washed beautifully and is soft and comfortable to wear. Such a difference in warmth, you much more snuggly when wearing them! Definitely be back to buy more❤️

Merino Long Johns / Leggings

I got these for sleeping in while on an alpine hike. They are super soft, warm and comfortable. They are close fitting so easy to layer under other items. They will be a staple in my winter layers

Merino Long Johns / Leggings

I have had Brass Monkeys leggings before in size XL which is about a 14 in my opinion. This time I bought 2XL for a looser fit. I'm happy enough with my purchase. In my experience they don't last forever but wash well, keep their shape and are opaque. Good value.

Merino Long Johns / Leggings

Thank you! Mums loves her Mothers Day present. No more cold legs in winter. They are just the thing she has been wishing for.

Merino Long Johns / Leggings

The wearer finds them comfy & warm. Ordering and delivery were eady and quick. Thanks.

Merino Long Johns / Leggings

Very prompt delivery. The leggings fit now that I know the size for me. I don't know how well they'll wear but they seem sturdily made. Overall experience is satisfactory. Thanks Smart Merino

Merino Long Johns / Leggings

Ordering and payment were easy, the leggings arrived quickly without fuss and the warmth and laundering quality are excellent. The fit is smallish for a size 14 (XL) but acceptable. Overall I'm happy and will probably be back for more. Thanks, Smart Merino.

Merino Long Johns / Leggings

I have the tops, now invested in the bottoms. Excellent and cheaper than Hanson.
