Customer photo review of Merino Long Sleeve

Great fit and soft comfy merino!I ordered another one straight away!

Customer photo review of Merino Long Sleeve

I’m very happy with my top. Although I’ve not yet worn it in cold weather it seems as though it will be up to the job when camping etc and will definitely buy another. It’s cheaper than icebreaker which I usually buy and not made in China which I wanted to avoid due to political issues.

Superior product in every way, and excellent service

Excellent merino product, and delivery was exceptional

Easy purchase, first class service, item is of good quality comfortable and warm.

From the beginning to the end the service and feedback to any of my queries was dealt with in a very timely manor. Customer service today is a dying art and in this case I was very impressed. Maria keep me informed all the way through and so helpful. Thank you to you and the team.

Go to clothing for the winter months

Wore them for the first time today while riding my motorbike in a cold southerly wind. So comfy I didn’t even notice I had them on. And I felt warm even riding at 100kmh. They are going to get a lot of use over the cooler months. Very pleased I bought them.

Customer video review of Merino Long Sleeve

Best for comfort and price made to last. The best protection to wear close to your skin. I use them for cycling and as a base layer every day for casual wear. I even sleep in one summer to winter. Love them 😍

Customer photo review of Merino Long Sleeve

Excellent product, will be using it all winter! Super quick delivery too, thank you.

Customer video review of Merino Long Sleeve

I usually buy Rapha base layers which are super comfy but I think your brand is a bit more longer wearing and price point is great. I wear a small which is a great fit but the sleeves could be an CM longer that would be perfect.

Customer video review of Merino Long Sleeve

This long sleeve top is made from thicker, stronger fabric than its competitors. M size is a snug fit on me. 👍

Customer photo review of Merino Long Sleeve

Received my tops yesterday and threw one straight on. Great comfortable fit, not too tight, soft and warm against the skin. Motorcycle meet tonight so it has arrived just in time as temperatures dive into low digits. i will be pairing it with my thermal pants also from Smart Merino. Great to support small New Zealand business, NZ wool industry and material and made right here in Kiwi land. Top marks to Smart Merino. Thank you once again.

Customer video review of Merino Long Sleeve

It is comfortable, you don't even notice you wearing it. I like the slightly longer tail on it that doesn't pop out of your pants when you bend over. Most importantly, is does what it says on the box. It's warm. 5 stars

Initially I didn’t think the merino top was very warm, but I’m finding that the more they’re washed the better they’re getting. I’m really happy with my purchase, especially the long tail which is great for keeping my back warm. I’ll definitely be buying more. I can’t speak highly enough of the advice and service I received from Chris and his team. Thanks for being so helpful. 😊

Great product - I would be happy to pay more for a taller fitting.

Keeps you warm even at night ,better than pj's on very cold nights.

Hard to get bigger sizes. Garment true to size and very comfortable. Great purchase.

Purchased this for my partner, she loves the fit and the comfort. We are happy with the quality of the garment. The price is good and delivery was fast. Will recommend this to everyone.

Love the fact that you have big sizes. Also the crew neck slightly lower so you don’t feel strangulated. Very comfy. Thank you

Excellent for golf and biking😎

I bought your thermals for my husband who is always complaining about being cold and over the years of buying him thermals that didn't have any quality about them I thought I would try your brand - he loved the items straight off - great fit & kept him warm all day. Thank you.

Good quality and fit. Very happy with the service, fast delivery and reasonable price. Am looking at purchasing again so I can move my old thermals on.

I just love wearing it

its a nice thing to wear

Well made, great fit, love it

A quality garment, well made good fit and warm. The best themal i have worn

The fit of my 5xl is snug, kiwis must slimmer in winter

I love my long sleeved merino tops. I bought two, then two more and today I received the two pairs of long johns I ordered just two days ago. I’m 71 years old and I have no plans to be cold ever again because I’ll wear my woollies everyday and everywhere.

Item was as described, size was correct. Fast delivery.

I have Icebreaker product and these are as good if not better and for a cheaper price. Can’t go wrong!!

What can I say....brilliant !!!

Best ever

Prompt service and perfect product.

Very warm

Great quality and service

Great fit, great quality and fantastic delivery. Very happy.

Bought it for my son who works outdoors and also hunts. He said it's easy to wear and makes a difference on frosty mornings. His 1 recommendation is that the cuffs could be tighter so that when he rolls his sleeves up, they stay up.

I bought this for my brother whose birthday was 23rd June so its arrival was very timely. He wore it to a Gymkhana where his 8 yr grand daughter competed. He told me it was 'lovely and warm' yet not bulky. Thank you for a quality product. Cecilia
