Kept me warm in v cold conditions

Best ever

They fit just as they say and the warmth is great. One doesn't realise just how much heat is lost or cold felt through a pair of trousers or jeans in winter. I wish I had done this months ago.

Warm, a little tight around the thigh

The long johns are warm and mostly comfortable to wear. They are however quite tight around the quadraceps/thigh, a thigh measurement alongside the waist measurement would be helpful.

Not too shabby

After the first night, they started to fit better, but considering that I have 5XL track pants that fit better than these 8XL?? long John's, I expected better. But they are comfy and definitely keep you warm on cold nights so there is that. :)

Why I should be your distributor in the states

Smart merino is an awesome product, it is legend. I purchased a long sleeve shirt at the outlet store north of Upper Hut in March of 2020. I have worn it extensively to work, hiking, skiing and just living in it. I live in Colorado where we have a 60 day summer at best. I live at 2,600 meters and play at 3,200 frequently. I have searched the internet for anything similar and no such material is available. All of the reviews for wool shirts and pants are abysmal. Anything similar is nylon and gortex and polyester, all just plastic/ petroleum. I love this material! it is strong and does everything that all the "high tech" fabric does. It has not faded or stretched out and has stayed durable after one year. I've worn the shirt for at least 25 weeks this year. It is my second skin. There are so many stores that I believe would jump at this superior product. If your looking to expand into a market of nature lovers who hike, bike, climb, ski, kayak and live outdoors please consider this an offer. Colorado has about the same population as New Zealand and a very similar state of mind when it come to the outdoors and the environment. Your products are worth my enthusiasm to share with others here. I have never been as excited about any product before and I want to share it. It's just that simple. Please contact me, Matt Goodrode
