Arc’teryx Veilance occupies a unique space in menswear, blending the brand’s legendary outdoor performance with a modern, minimalist interpretation of classic garments.

In their Spring/Summer 2021 collection, they extended this philosophy to a new material: a lightweight performance wool, introduced in the Haedn LT capsule.

The Origins of the Haedn Line

The Haedn line began as a cold-weather concept, featuring first a blazer, then an overshirt/jacket. Both were made from a dense, felted wool with a synthetic backer that was both classic in appearance and highly functional.

Where those earlier pieces were built for warmth, the Haedn LT strikes out on a different path.

Veilance Haedn LT

The LT pieces still belong in the Haedn line in their use of wool and in the classical look of the material. Heathered gray or dark navy; nothing eye-catching in that!

The LT capsule is expanded to offer a full suiting option, though: There is not only a blazer, there are also a (short-sleeve, later expanded with a long-sleeve) shirt and pants.

LT: Light, for the Heat

The “LT” (Lightweight) designation is taken seriously.

This isn’t the brushed, heavy wool of its predecessors. Instead, Veilance uses an incredibly fine 18.5-micron merino yarn, weighing in at just 145 grams per square meter.

To put that in perspective, I have canvas paper in my office that’s twice as heavy. The result is a suiting option—blazer, pants, and a short-sleeve shirt—that feels almost weightless.

Material and Feel

Treated with a Durable Water Repellent (DWR) finish, this “lightweight performance wool” feels soft, supple, and surprisingly strong.

The density of the weave inspires confidence in its durability, yet the fabric remains highly breathable and comfortable directly on the skin.

Like all quality merino, the Haedn LT garments drape beautifully, resist wrinkling, and feel as if they are hardly there at all.

Having now worn the “suit” in summer conditions, I can confirm it performs as expected, keeping me cool and comfortable.

While I haven’t tested it in a summer downpour, these pieces aren’t intended as rainwear. They are designed for the heat, offering a level of comfort and polish that traditional suiting can’t necessarily match, at least in a DWR-treated material and with wool that’s backed with nylon and elastane.

A Study in Minimalism: The Look and Style

Aesthetically, the Haedn LT capsule is classic Veilance. Offered in timeless heather gray and dark navy, the style is a severe, considered minimalism.

There are no visible buttons on any of the exteriors. Pockets are seamlessly integrated. Every line is clean and uninterrupted.

The Haedn LT Pant

The pants are perhaps the most subtly unique piece. An onlooker would be hard-pressed to notice the Veilance-typical articulated patterning, which uses angular seams and gussets for unrestricted mobility.

The front pockets disappear into the side seams, while the angled back pockets are protected by subtle flaps—one of the few details that hints at the garment’s technical origins.

As expected, all internal seams are taped for a clean finish and enhanced durability.

The Haedn LT SS Shirt

The short-sleeve shirt maintains the minimalist ethos, with its small snap buttons hidden behind a clean placket.

It features a single, nearly invisible chest pocket, closed with a hidden, tone-on-tone zipper.

While a dress shirt pattern isn’t designed for climbing, the ergonomic cut provides ample mobility for everyday wear.

Sizing-wise, I opted for a Small over my usual Medium, as it offered a slimmer, more defined fit through the waist.

The Haedn LT Blazer

Like the mainline Blazer LT, the Haedn LT Blazer is a curious and compelling garment. The merino wool feels even lighter than the Terratex fabric of its sibling, making it an excellent choice for maintaining a polished look in conditions where an ordinary blazer would be unthinkable.

Unlike its cold-weather counterparts, it lacks the collar fastening to be worn fully closed. However, the wool has enough structure to hold that shape reasonably well if you, like me, have a fondness for the look. The blazer is finished with two vertical hand pockets integrated into the seams and two internal zippered pockets: one passport-sized, the other perfectly suited for a wallet.

Combinations and Final Thoughts

As a full ensemble, the Haedn LT outfit is elegant, with a distinct minimalist severity. But how do the pieces work individually?

The Pant: Works easily with almost any shirt, though it retains the character of a suit pant.

The Shirt: Combines well with most pants and has a unique character that sets it apart from a typical dress shirt.

The Blazer: This may be the trickiest to style. As with any blazer, pairing it successfully requires consideration. More than anything, it requires the right personality—it’s a piece for a man who is comfortable wearing a blazer and making it his own.

The Long-Term View

It’s been a while since the Haedn LT pieces were in the Veilance collection, but they remain favorite pieces in my Veilance wardrobe and in my rotation.

For summer “suiting”, these pieces are hard to beat when a formal look is required or desired, but they really function best as a sort of suit, all the pieces combined with each other.

The only variation I can recommend, style- and function-wise, is replacing the shirt with another summerweight piece, preferably with only a rounded collar (read: a T-shirt).

They have all held up very well and still function as they should, comfortably and sharp.

One peculiar detail has emerged: There has been no re-release of these pieces in the last years, but Arc’teryx Veilance’s Convex Wool Blazer and Pant (of 2024/25) are a very slightly different material, basically the same cut, and an only slightly darker color in their Black Heather colorway (plus a new “Ganache Heather” brown).

Thus, as usual for Veilance, lines and pieces disappear, but the basics of (more or less) timeless menswear staples remain and new iterations of former lines re-appear.
