Customer photo review of Merino Men's Long Johns

A delight to wear. The first thing you notice about these premium thermals is how thin and how light they are (I weighed them and they are 250g). They have the thickness of much underwear but wearing merino wool against the skin is a delight and being so thin, you can wear these under pretty much anything.As you would expect for this sort of premium product it is extremely well made and stitched, the material has a lot of elasticity without losing its shape and being merino-wool it is extremely warm (surprisingly so) and comfortable when wearing and the sizing seems accurate. They look like they are built to last as well as for comfort and warmth. The outdoor hiking equivalent of sexy underwear I would say. They are a delight to wear, do not change the feel of the clothes you are wearing over them (in general whilst I love thermals, you always know you are wearing them).These are wonderful thermals. They are at a premium price point but they are a treat to wear, which I never thought I would say about thermals.

Merino Men's Long Johns

Absolutely great products and awesome to deal with if there is a glitch.. a big thank you to Saphire and the team for being awsome

Merino Men's Long Johns

I bought a pair and I was so thrilled with them I bought a second pair..although they are the same size the 2nd pair seem quite a bit tighter with little stretch almost like they have been cut out if fabric the wrong way so was disappointed as they are a bit uncomfortable to wear😞 but quality seems good

Merino Men's Long Johns

I had bought a pair and loved them so much so I bought a second pair the same size but they don't fit as good... they don't have the same stretch and comfort and cut weird around the waist.. I was thinking they might give after wearing them but they didn't sadly...but other than that the first ones were great

Merino Men's Long Johns

I love these Merino leggings and I love that they have big sizes for the bigger person, which are hard to find. Superb quality and super fast postage

Merino Men's Long Johns

Just what I wanted for the Central Otago Cold Winter However I did have a problem with there being No Fly opening - Are disabled and only have the use of my right hand which calls for a different mind set

Merino Men's Long Johns

Very well made Long Johns. The only improvement would be the addition of a fly for simpler urinating for the older school .

Nice to see a South Island company making woolen garments.

I am a motorcycle enthusiast, I need to be warm at my advanced age! :-) The items are toasty warm, and feel nice - not scratchy I recommend to everyone

Merino Men's Long Johns

Merino Men's Long Johns

I chose the wrong size 😭. Was meant to get large. Oh well someone will love them lol

Merino Men's Long Johns

Great long John's have worn shorts all my life all year around out on the farm now I'm nearly 50 I'm feeling the cold a bit, just like wearing shorts with warm comfortable legs

Merino Men's Long Johns

Hubby really suffers from the cold and havd tried many different thermal options which were o.k however these take comfort and warmth to a whole new level.

Merino Men's Long Johns

Lovely and warm. Not a scratchy label. A bit tight, I'll get the next size up next time. Hopefully this will get me a discount :-)
