Introduction

A shirt so light you forget you’re wearing it

For anyone who wants to feel like they’re hiking naked! At only 53g, we’ve created a shirt so light that you might just forget you’re wearing it.

The excellent breathability of the Pertex Quantum Air fabric means that sweat dries in an instant, and with a fit that allows outside air to easily circulate through the fabric, this shirt lets you stay comfortable even on very hot days.

The women’s version has a revised fitting and details with updated pattern, featuring more relaxed fitting for better ventilation.

The collar can be turned up and fastened in strong winds, making the shirt adaptable to rapid weather changes.

Product Story

“I wanted a shirt”

Akira Natsume, Yamatomichi Founder

A merino wool base layer with an ultralight wind shell or a breathable rain shell seems like the perfect choice for the ultralight hiker. However, always going hiking in the same clothes gets a bit boring eventually, and I think hiking should be not just practical but also fun. That’s why I thought a shirt for variety would be a good addition to our lineup.

For the material, my initial choice of 100% merino wool was certainly comfortable, but the fabric weight of 200g/m² was just too heavy and warm during the hot Japanese summers. As a self-proclaimed wool lover, I was tempted to go ahead anyway, but somewhere in my heart, I wasn’t convinced that wool was the right answer.

While I was in the process of trying a variety of other materials other than merino wool, I stumbled on the idea of using the lightweight Pertex Quantum Air fabric that’s used as the facing material for our Alpha Anorak. Up to that point I had been keen on using natural fibers like wool and bamboo, but then I started thinking that if I was going to focus on lightness it might be ok right to go with a 100% synthetic fiber, and at 50g/m², the Pertex Quantum Air is almost as light as air!

The resulting prototype was as extraordinarily light as I had imagined, and many people were surprised when they picked it up. The one thing that worried me was its odor resistance. Since the shirt was 100% nylon, I didn’t anticipate odor resistance like what you get with wool or bamboo. As someone who wanted to avoid going around the mountains in smelly clothes, I was concerned, but as I actually tested the prototype I soon understood that I had nothing to worry about. This UL Short Sleeve Shirt is not only light, it also dries super fast.

You can wring it almost completely dry in a towel after washing and the remaining moisture will dry quickly when you walk around wearing it. Thanks to this, if you come across a stream or lake on your travels and give it a quick wash, you can just put it right back on again and keep on going.

Form and Function

The emperor’s new clothes?

We’ve created a shirt that at only 53g (S size) is much lighter than most T-shirts. You’ll forget you’re wearing this, but contrary to the emperor, you won’t be naked!

Super Compact

The shirt is so compact it fits in the palm of your hand when folded, making it perfect as a change of clothes when hiking or traveling.

Raised Collar

Buttons on the inside of the collar allow it to be turned up and fastened to shield from the wind and sun.

Super fast-drying

Quick wash? Just rinse in a stream and wring the shirt and you’re good to go.

On and Off the trail

Wear the shirt as a thin windbreaker on top of one of our Merino T-shirts or bring it as a change of clothes for when you get off the trail and head for the nearest bar.

Form follows function

The Pertex Quantum Air is remarkably wind-resistant, fast-drying, and pretty durable considering its super lightweight.

We think that the essence of a shirt’s functionality lies in the excellent wind resistance unique to woven materials, along with good ventilation and easy circulation of outside air, aided by snap buttons that allow for quick opening and closing.

We thought we didn’t need a breast pocket so decided to do without it.

Material

Breathable yet Windproof Pertex Quantum Air

In the harsh mountain environment, where the weather and temperature rapidly change with strong winds and intense sunshine, both breathability, and windproof property are required at the same time. The UL Short Sleeve Shirt is made of Pertex Quantum Air, a 20 denier fabric that is ultralight, yet has excellent durability and breathability.

Instructions

Snag and Pilling

The Pertex Quantum Air may develop snag and pilling when constantly rubbed against a rough surface.
Outlined below are the situations where snag and pilling are particularly likely to occur and how to repair them.

How Snag and Pilling Occur

The following shows a couple of examples of pilling and snag on our UL shirt. Please note, however, that similar situations below don’t always result in pilling.

Friction and contact against hard and rough objects such as Velcros and coarse mesh.

Repetitive contact and friction in the same spot, often with shoulder belt and hip belt of the backpack, or car’s seat belt.

*Damage can be more noticeable when the fabric is wet with sweat.

Temporary Repair

Snag
Lightly stretch the fabric so that the distortion of the fabric is corrected. If it is still snagged and distorted, use a low-temperature iron, apply a covering cloth and reshape the fabric while lightly stretching it.

Pilling
Using a pilling remover, cut the furballs on the surface of the fabric. Do be careful not to cut the fabric of the shirt. Please note that when pilling is removed, the yarn composed of long filaments may be cut and the strength of the fabric is weakened or a very small hole may occur in the fabric surface. You can also lightly sear the pilling with a lighter to melt the fuzz. This will reinforce the area around the pilling and prevent further tearing, but too much burning may cause holes in the fabric and harden the melted area.

Disclaimer: Please note that the above is only provided for reference and that we do not accept any responsibilities for any damages as a result of following these instructions.
