Wear your Patagonia 1 T-Shirt on the trail, road, or climbing route on any hot day.

The Patagonia Capilene 1 T-Shirt lets you keep your cool when you exert in hot weather. Wear this silky feeling athletic-fit T-Shirt alone when you run, hike, bike, or climb—breathable Capilene fabric wicks your sweat away from your body so you stay dry and comfortable. In cooler weather, wear this wicking tee as a base layer so you don't get swampy underneath your lightweight jacket. Patagonia treated this crewneck tee with Gladiodor odor control so you won't reek, even after a long, sweaty trail run.

Great T

Best T I own. Last time I bought a poly T was in 2004 and it was a "Patagonia Silkweight Capilene T-Shirt - Men's". The Capilene 1 T-Shirt is lighter than that one (which I still use) and longer. That makes it unlikely to come untucked while climbing or other activities.

I have worn this on 5 winter hikes since I bought this on Jan 19th. The days varied in length from 5, 6, 7, 8, to 9 hrs with max of 19 mi and 3300 elev gain with snowshoes in temps ranging from 0° F to 30° F. A wide variety of strenuous winter conditions. On each hike it served great as a base layer. At the car at the end of each trip this T was dry. I also worn it three days in a row at home to work to test its odor properties. Held up great. I decided to wash it after day 3 cause I thought I should, not because it smelled any worse than on day 1.

It is a bit pricey but I will probably buy a second to take backpacking this summer. I usually like to sleep in a cotton T that I do not wear hiking. This one is so good that I plan on wearing one during the day, rinsing it out, wearing the 2nd to bed and on the next day's hike. Got a 11 night trip planned so we will see how this works.

The perfect shirt for any kind of physical activity. Really comfortable and the wicking capabilities are second to none. Love it as a baselayer for snowshoeing too.

How does this perform under a pack? I want something that can take the miles with my 10L trail runner or my 55L business-time pack.

Responded on

The Capilene 1 T here is great under a pack. Comfy enough to wear for miles underneath and durable enough to last.

great technical tee

This is a great shirt. It has a good fit (I'm 5'6" 135lbs and a small fits great), is super comfortable, and dries quickly. The only downside to this shirt is how quickly it absorbs odor. I tend to wear this shirt for runs and day long excursions, but prefer wool for extended trips to due the smell Capilene accumulates. Overall, one of my favorite synthetic shirts.

weird fit for me

This shirt has great material, but the fit was way off for me. I tried a couple on in size medium and fit great through my torso, bu the sleeves felt like they were for an XL. If it happens to fit you, I bet it is a great shirt.

Responded on

These shirts definitely have an athletic cut to them. I have a medium with the opposite problem. The torso fits fine but the sleeves barely come down to mid bicept. Seems like patagonia is messing around with the sizing a little bit.

Responded on

I have noticed some variability in sizing within model years and Patagonia loves to tweak their stuff year-to-year.

What else can be said?

These shirts are great. Clearly the standard for wicking t-shirts.

I have three total. 1 classic navy, 1 feather gray, which are great. However, I also ordered white, which seems to be a much thinner fabric, that gets stretched out much more easily. The material feels like something between a standard cotton undershirt and medical gauze.

Great capilene top

Your standard good quality capilene t-shirt. Multi-purpose, good fit, smooth material and bright colors. It feels good to wear and wicks well. That's a 5-star tech-T in my opinion.

The best short-sleeve baselayer

Capilene is the best fabric for baselayers other than perhaps high-quality merino wool. I prefer thin base layers because I can more easily later them (long-sleeve over short-sleeve) and they dry quicker.

The design on the Cap 1 S/S is great, too. Like its long-sleeve cousin, the torso length is also slightly long so the shirt can be tucked in to prevent drafts. The torso is also tapered for an athletic fit, and the sleeves are long enough to be there, but not long enough to needlessly flap around.

I use the Cap 1 running in warm and hot weather, and in spring/fall under a Cap 1 short-sleeve.

Buy a wardrobe seriously

I have six of the Patagonia Capilene 1 Black Large shirts. Now I will not wear any other shirt. I've been wearing them every day for two months plus and I'm wearing one now. Any condition. Dry. Under warmer layers, warm. It's hot here in the NM desert, and I'm cool. Great in the mountains also. Best of all, chicks just can't get enough of me after my Backcountry shorts and esp. this shirt.

Great Shirt

I bought this for those summer hikes that are scorchers, and its great. Wicks great and helps wonders to keep me cool. Also, great to wear for everyday use. Love the shirt, plan on buying more.

long sleeve too

I have the long sleeve version + am pretty happy w/ everything but the smell that eventually creeps up late in the day despite the measures patagonia has taken. This minor setback that I probably would have accepted if I had not had the pleasure of owning a Wool 1 layer from patagonia.

The long sleeve is still my go to for cool morning runs b/c its so comfortable + great at wicking.

Anyone know about the effectiveness of the...

Anyone know about the effectiveness of the "gladiodor odor control"? Trying to replace old polypro.

Responded on

Gladiodor works really well in the Capilene 1 T and other Patagonia Capilene tops and bottoms. It stays noticeably less stinky that my other polypro shirts I've got.

Responded on

I bought this shirt specifically to see if the synthetic odor controls have gotten better and could compete with wool yet. The answer was a quick NO. I still like the shirt for all the other reasons people mention, but only if I am only going to wear it for an hour or two and then it goes into the wash - otherwise it starts to stink.

Responded on

From what ive experienced, the benefits of gladiodor really shine after the sweaty shirts sit around for a bit without being washed. For example, after running or working out hard in the capilene1 and in a Nike Dri-fit. If you leave both shirts laying around for a day or two without being washed, the patagonia tshirt's stench is effectively controlled to the point where i could put it back on and wear it again. Not so for the dri-fit tshirt. So this type of shirt is good for sweaty endeavors where a washing machine is out of reach for extended periods. Example being multi-day backpacking trip, backpacking europe, or dirtbag climbers.

Responded on

Better than old-school poly-pro, but it still stinks after some use!

The Chosen One

This shirt is tops! The only baselayer that ever came close was the Golite LW C-Thru from a few years back. Cap-1 is much more durable and less prone to snagging the forest as it flys by. I live on O'ahu and run the rainforest, which means all out wet, windy and cool (chronic hypothermia kine weather)or hot, still and humid (Think Kona winds). Most days are some of each. This shirt allows me to continue without having to carry surplusage. The updated fit is a great improvement and will keep your purchase from becoming an 70s-80s half-shirt after a few washings. Yes, even plastic fibers can shrink. Probably best to hang dry. Despite the latest technologies and claims this shirt will eventually begin to smell abit like the dog blanket. Still yet, it is my staple shirt!

Great Shirt

Super lightweight and comfortable shirt. The silk weight is perfect for hot weather activities and for layering in colder weather. No need for anything else here.

nothing special

not a bad tech shirt, but not anything special. it works fine, but i think it is overpriced for an undershirt, which would be the way i primarily use it. too form fitting for me to wear to the gym

5 5

cool shirt

Whenever its hot in the summer this is one of my top choices to wear. It is form fitting and has a little extra length to it which is nice for sports like biking. I also like it because the sleeves are short so they don't get in the way of your activities.

Really dig this shirt

The fit of this shirt is great. I'm 6'3", 190, and shirts that are long enough are typically as big as parachutes around my torso, but this has a nice fit cut; a large is plenty long and not too baggy. Very comfortable as well; I don't notice it when I'm working out which is the best compliment I can give it. Form and function are both great.

Very good shirt

Good for hot weather, or as a base layer in the cold. It's definitely a workout shirt. Fits well. Patagonia has lengthened their performance wear over the last couple of years. Their capilene used to be a half shirt on me due to a long torso.
