The Trino Tights really will become your winter best friend. Unlike your standard windstopper or softshell trouser, the Trino Tight is both, combining water resistance, windproofing and durability with unrestricted mobility, unrivalled breathability and comfort for long days out. 

What makes the Trino Tights so clever is the way Arc'teryx have placed certain fabrics in certain areas to maximise overall performance. Gore Windstopper is lined throughout the front of the tights to provide you with a totally windproof, highly water resistant and durable barrier against the elements, while Arc'teryx's own Atreus fleece fabric is placed around the back of the legs to allow wind to pass through, sweat to escape and mobility to be increased. The combination of these two fabrics ensures you have a completely unrestricted experience without sacrificing on weather resistance or durability. 

Although the Trino Tights are largely designed for running and high intensity activities, they're just as well suited to general walking and travel duties thanks to the high comfort of the two fabrics. Articulation in the knees makes them perfect for anything from running to walking the dog on a breezy day. If you do happen to get caught out in the rain while carrying out said activities, the tights will dry exceptionally quickly and are lightweight to pack down into a rucksack. 

Pockets wise, you get two small zipped pockets on each hip to store essential items, while reflective logo's allow you to be seen in low light.

Pro Opinion

Hannah Campbell - Tried out the Trino Tights

So the Trino tights have been designed to fit into Arc’teryx’s Endorphin Performance Range – which is designed predominantly for Mountain and Trail running. However, I think that this puts this piece of kit into a very slim activity range. What I’ve actually found is that they are much more versatile then that. I’ve used them for climbing (both indoor and outdoor), outdoor yoga (a bit too warm for most indoor yoga studios), hiking, mountaineering, general commuting and daily use – as well as the trail running use they are intended for. So what makes these so damn awesome? The fact that they’re windproof, water resistant, highly breathable, durable and comfortable as hell. So how do they do it? Let’s look into the ever exciting techy stuff!


The Fabrics

And this is where Arcteryx blow me away every damn time. These tights feature Arc’teryx’s composite mapping technology – which is basically just a fancy term meaning they’ve put very clever fabrics in very clever places to maximise the garments performance. The front the Trino Tights house a Gore Windstopper membrane, making the front of the tights totally windproof (really important when you’re faced with a freezing headwind). The material on top of that membrane is coated with a DWR (durable water repellent) fabric treatment which means that the tights are also highly water resistant (if you do get caught out in conditions where you are soaked through, then these tights also dry exceptionally quickly), without losing their breathability. Then, on the back of the tights, Arc’teryx use their own air permeable fleece fabric called Atreus which allows sweat to escape, increases the ventilation and increases the freedom of movement.  The combination of these two fabrics results in a pair of tights that can keep up with you throughout a really wide range of activities, including high-output training.

The Features

  • Wide waistband with an adjustable elastic drawcord.
  • Two zipped pockets on the hips (one with a media hole).
  • 23cm zip at ankle with gusset so they can fit over big mountaineering boots.
  • Flat Locked seams for increased comfort and reduced chafing (important!).
  • Articulated knees

The Fit

Even though Arc’teryx brand these as ‘Tights’ they don’t fit as snug as your standard ‘sports leggings’. They are, however, slightly more slim fitting then some of their other trousers. We’ve started referring to them instead as ‘Trouts’ – feel free to do the same! The fleece material in the rear sits snug to your hips and bum, and then they sit loose throughout the rest of the garment for increased mobility and range of movement.


The Good

Everything everything everything.

I was pretty impressed by these leggings when I first read up on them, and then I was bowled over by them when I took them into the mountains. They’re much lighter than my other winter-weight trousers, so if I was going on a multi day trek then I could just roll them up and stuff them into my pack and they wouldn’t make much of a difference to the overall weight at all. Also, I know that I can pop these on and they’ll suit me in whatever crazy adventure I end up falling into (my plans are never set in stone!)

The Bad

The hip pockets are tiny (they don’t fit my phone) and barely fit a medium sized energy gel in them. So if you’re running in them then you may need to also wear a running belt. If you already do so and this doesn’t bother you then great. I, however, hate wearing extra bits on me when I run; I’ve never been a fan of running belts or vests. Their Sunara tight (summer weight training tights) feature a small elasticated pocket on the outer right thigh. It doesn’t get in the way when I run and my phone never falls out. It’s something I’d LOVE to see in future models of the Trino.

The Ugly

Honestly, I struggled with this one. If I was being nit-picky then I’d bring up the colour thing again. They are currently only available in black (If you work for Arc’teryx and you happen to be reading this then – Hey! I love them! Please give me more colours so I have an excuse to buy more!). Their price point is also a bit higher than other winter weight trousers (RRP £120), but when you weigh up the versatility of the Trino Tights in comparison to other softshell trousers, teamed with the epic fabrics and bomb-proof durability then it’s easy to see why that’s the case.

As a Whole

I think you know what I’m going to say after the vibe of this whole post- I love them. And if you can bite the bullet and invest in some winter trousers that’ll do just about anything (I’m sorry, I know it’s so close to Christmas!) then I can guarantee you’ll love them too.


As usually, if you have any further questions, or if you have these too and want to add a note about why YOU love them, then leave me a comment below or fire me an email!

Thanks guys!

Excellent customer service. Really detailed easy to understand product descriptions on the Trekitt website, and gear reviews on the Trekitt YouTube channel made it so easy to choose the right backpack for me.

Amazing service! Very helpful in regards sizing and what most matched my needs, despite this being done over the internet. YouTube videos of products being examined are very useful also. Would definitely use again, very fast and efficient delivery. Brilliant! Highly recommended!
