You asked for it and we listened. The Ottie Merino Men's Long Sleeve Merino T-Shirt will keep you that little bit warmer in winter and the sun off when you're hiking when it's... well, sunny! 

Like with our short sleeve merino t-shirts, our long sleeve merino hiking tee is lightweight —made from 165gsm 100% merino jersey fabric—relaxed fit, to give you a little more room to move, and a bit longer than a lot of tees out there, to avoid ride-up and to keep your back covered.  

Ethically made in Australia (Melbourne, in fact) from 100% Australian grown mulesing-free merino wool, this tee is designed for those weekend day hikes, more arduous multi-days, and everything in between. It makes great casual wear too, and is the perfect relaxed fit base layer for your layering routine. 

- Made from 100% Australian merino wool
- Relaxed fit for normal bodies (no clingy 'athletic cuts')
- Longer cut to avoid ride up when wearing a backpack, for easy tucking, and ideal if you're on the taller side 
- Crew neck with self-fabric neckband
- Available in small to xx/large (see size chart)
- 100% mulesing-free 
- Made in Melbourne
- Sweatshop-free!
- Australian Made certified
- All the benefits of merino wool—odour resistant, moisture wicking, temperature regulating, super soft, biodegradable, and comfortable AF!
- Designed by hikers, for hikers (and climbers and runners and... whoever, really)

Love the feel of my long sleeve T

Whilst still only new, I love the feel of this merino T, very comfortable. More importantly, I give a ‘five star’ rating to Paul and Kath for their excellent service and follow up.

An absolute beauty of a hiking and everyday shirt!

I've been wearing the long and short sleeve variants of these amazing Australian made products. Supurb moisture wicking aspect as expected and amazing quality. Paul and the team have also been very helpful with after sales support of products and happy to answer any post sale questions.
Most importantly, Australian made!

Heather Lister

Very comfy and the wrong size I ordered was posted back to you on 25 th May. I hope you have received it. I would be pleased if you could let me know that you have received it.

Sally Court
Soft and strong.

I love natural fibres for my health and the health of our world. I believe the merino sheep are loved, valued and cared for having come from a wool farming heritage. I chose a men's long sleeve t shirt for the wider neck. It is soft, warm, doesn't harbour toxic odours the way polyester does and when camping can be worn for many days without washing. Who needs to go camping ???lol. My clothes are wool, hemp, organic cotton, linen, bamboo and tencel. Thanks for being part of my life. Sally from Gippsland, Victoria.

Love the Loose Fit

I bought two of the long sleeve tees for a recent Grampians Peaks Trail walk. I loved the loose fit, super comfy even with a heavy pack and tough conditions. Dried really quick at days end, wicked really well, didn't stink up. Wore it as a tee but think it would be a great base layer.


Very happy partner

Brilliant shirt!

Fit is as the website describes, and the material/manufacturing quality is great. Getting some more

Nice shirt

Nice shirt, will add it to my sleeping kit for hiking. Already have 2 short sleeve t-shirts, which are also good. Like the fact these are locally made. Some more colour choice would be nice.
