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)

Quality Aussie Made Long Sleeve Merino T-Shirt

Medium size long sleeve tee fits my athletic 6'3.5" lanky body like a glove! Feels extremely comfortable to wear on my psoriasis covered skin. Extra length at the bottom of the tee is a real game changer for taller people. I didn't experience any ride up whilst hiking two days with a heavy backpack on my back. Amazing moisture wicking capabilities and held zero odours after two days of +12km hikes. Australian made. Great overall choice of colours but would also love to see navy blue added in the future. Unfortunately Otway Fern was unavailable in my sizing so opted for the Plum coloured long sleeve tee.

Service excellent

Sizing is great. Extra length at back is perfect. Fabric feels are also delicious.. Such a silky feel on. I dont think one can go back to cotton feels. Especially in the north.

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!
