If anyone says designing great hunting apparel isn’t rocket science, they aren’t designing hunting apparel at Pnuma. Based on the same principle of a NASA spacesuit, the hollow-core, chemical-free yarn of the lightweight, ultra-comfortable Tenacity Coolcore® Performance Shirt is engineered to eliminate areas of sweat concentration and spread sweat throughout the shirt. By reducing sweat concentration and allowing moisture to spread, wetness evaporates and dries faster. Coolcore is also proven to reduce fabric cling to your skin/body so you move unrestricted in the warmest temperatures and times of highest exertion. As temperatures drop, add the IconX base layer top beneath Coolcore® to keep you warm and comfortable – and extend your use of the Coolcore® shirt throughout your season.

  • Lightweight, athletic cut
  • moisture-activated cooling
  • Eliminates areas of heavy sweat concentration
  • Rapid evaporation and drying
  • Move freely with reduced cling of wet fabric to body/skin
  • Chemical-free wicking performance
  • Zippered pocket
  • Guaranteed for life

Cooler on the surface. Cooler to the core.

Inspired by the same cooling technology found in space suits, the lightweight, incredibly comfortable Pnuma Tenacity Performance Hunting Shirt is powered by Coolcore® fabrics. Coolcore® moisture-activated cooling technology is proven to keep fabric cooler when you’re in the heat of the hunt by immediately moving heat and moisture away from your skin. When dry, hollow-yarn chambers inside each strand are heated by your body to keep you warm. You’ll stay concealed and comfortable no matter how hard you hunt – and no matter where. Head to any location in the Tenacity Performance Hunting Shirt and Hunting Pant and you’ll send a message you’re coming in strong. You’re coming in tenacious.

  • Patented Coolcore® moisture management technology
  • Chemical-free, high performance wicking ensures long-term effectiveness
  • Pique mesh sleeve gussets for added breathability and ease of movement
  • SilverStrike anti-microbial odor control for improved scent stealth and freshness in the field
  • Flat stitching and seamless shoulders to prevent rubbing and soreness from layers or pack straps
  • Pre-curved elbows for ease of movement
  • Sleeve zipper pocket
  • Thumbholes for easy layering
  • Taller collar than traditional tee for comfort and protection
  • 84% Polyester/16% Spandex Jersey Knit
  • 8.5 ounces (product weight for large shirt)
  • Guaranteed for life

The coolest fabric there is.

The only fabric on the planet awarded the Hohenstein Institute’s Innovative Technology Award, Coolcore® Technology leverages proprietary, innovative yarn-spun micro-tubing within its weave, which holds heat and moisture, keeping surface material temperature up to cooler than skin temperature when wet. Where other products use chemicals, finishes, or other moisture-management additives that degrade over time, Coolcore® is completely chemical-free and will stand up to seasons of hard use and washing.

True sizing means true fit.

Whether you’re looking at hunting base layers that will keep you warm, dry and comfortable all day, outer layers that protect you from wild swings in conditions while you’re in the backcountry, or anything in between, the right fit is imperative for optimal gear performance. That’s why we offer True Fit on all Pnuma hunting clothing.

In order to ensure you get the right gear sized to your needs, we give you a 30-day True Fit period. Purchase any Pnuma hunting apparel products and if they don’t fit correctly or you’re dissatisfied in any way simply send them back within 30 days. All returned items must be in new, re-sellable condition. You’ll receive a full refund.

In addition to traditional medium through XXXL, all Pnuma hunting jackets are available in Tall sizes. We’ve designed them with an additional 2” in torso length and 1.5” in the sleeves. The inseam on The Insulator pant has an additional 2” in length. No more swimming in a larger size to get the length you need.

All of our pants, with the exception of The Insulator pant and base layers, are available by waist and inseam. So, whether you’re a 32”/34”, a 40”/36”, or any other combination, you can order the size that fits you, not just the size that fits most.

And since we know that the human body, at rest or in motion, has natural bends and curves in the arms and legs, every top and bottom in every layer we offer has active-contoured elbows and knees to help improve fit and function even further. Even our gloves are designed with curved fingers to replicate the natural shape of our hands.

That means you can order your size and head to the field with confidence knowing you have exactly the right gear - in the right size - for you.

SilverStrike™ Antimicrobial Technology. Nature’s scent control.

Microbes are living cells like bacteria, fungi and algae that can grow on many materials creating foul odors, discoloration, and formation of mildew and biofilm. Put your gear away wet and you know exactly what we’re talking about. The antimicrobial properties of silver, unlike harsh chemical treatments, have been known for centuries. Applying it to outdoor gear is still a great way to combat odor. SilverStrike advanced antimicrobial fabric technology prevents the formation and growth of bacteria and other odor-causing microbes, keeping garments smelling fresher—and you staying undetected—longer.

Great gear
Awesome shirt for mid-season. Cant say enough good things about all of my pnuma gear. I combine this shirt with other layers and no matter the conditions, I’m warm and dry. Pnuma fan for life!

Good shirt.
Great material and an excellent shirt. Runs a bit big but that's okay; extra sleeve length is a good thing.

A really great shirt
Very comfortable and perfect for layering. It is cool and the material is super quiet and very high quality. I just got back from Wyoming Elk hunt and wore this shirt as one of my layers everyday. I highly recommend this product. I am a big guy, 6' 2" and 280 lbs and the XXL fit perfect.

Really Nice Shirt
Really nice shirt, very comfortable and fits nicely. It works for a good base and won't make you sweat. I wear or another shirt by Pnuma for my base and both are really good.

You need this one!
Amazing!!! I am 6'2" 240lbs. Order this shirt according to the measurement requirements. I am pleased with the fit. It is definitely an athletic fit and will be an every day wear for me! I have fallen in love with this shirt. Love the mock neck and arm pocket with thumb holes. Wear this as a layer with the 1/4 zip and my Waypoint jacket. They go great together. I can't wait to wear this shirt for summer time fishing, hot Kansas dove hunts, and early season bow stands.

Itchy back panel
Great Camo pattern, but the back panel thread seam around the neck and trapezius area is abrasive and itches. That and the cost got 3 stars, great packaging but needs not to itch.

Returned this item. Appears well made but I did not like the collar. On me it rode high pressing into my Adams apple area of neck. Also Pnuma embroided if thats the proper word the sizing and care label which includes their Pnuma lablel about 3 to 4 inches down from the neck collar. What or how ever they printed that it is scratchy. On me the chest fit perfect but the arms were baggy. Great item just not for me.

Keeps mosquitoes at bay!
Love this shirt! I have worn it several times in weather that exceeded 80 degrees, it is cool enough to not overheat & I love not having to deal with mosquitoes all over my bare arms. I would definitely recommend this shirt!

All around gear
Great hot weather shirt. Works very well as layering too. Dries fast, and doesn't get that workout shirt stink after multiple days. Doesn't get hung up on thorns. No static. Very impressive shirt.

Not so cool
Wore the shirt for the first time here in Georgia. By 10am we were at 85 degrees plus. The day got to 98 by afternoon with heat index of 113. I was soaked. Felt like I was wearing a wetsuit. When I took it off, it was like I was peeling it off. The seams across the back are to much. The horizontal seam runs across my shoulder blades and the vertical seams run just inside my shoulder blades. When I put a pack on, those seams really rubbed on me. They are in a bad place being in a place that moves every time you move your arms. The pocket in the sleeve, to me was of no use. The material is stretchy making it very hard to operate the zipper one handed. Not what I was looking for.

Good shirt--a bit pricey
Great fit and quality of material. I like the pattern and the thumb holes. Given all of that, I feel it is priced about $30 too high compared to similar quality brands such as Kryptek and Sitka. If it hadn't been for the 10% Father's Day discount, I probably wouldn't have purchased it even to compare to the afore mentioned brands. Additionally, it would be nice to see a Military discount offered. Would like to see a bib-style pant for use sitting in the treestand.

Warm weather winner!
I finally decided to leave the Pnuma 1/4 zip wool top at home one evening when temperatures got a little warmer normal. Between the shirt breathing and a light breeze, it was more than pleasant. Extremely well built and durable, and surprisingly didn't stink like so many other synthetics. Awesome top for warm weather.

Tenacity hunting shirt
I recently purchased this shirt for Turkey hunting and very happy with performance and material in warm & cool days. Getting right Fit has been a little bit of issue with Pnuma clothing but have solved through exchanges.

Great for a Longsleeve
Let me first say that this is a great shirt and it has worked well for me for about 2 months of use. One thing to keep in mind is that it is still a long sleeve. I feel comfortable wearing this up to about 70 degrees without exertion and probably about 65 with exertion. Pnuma still needs to come out with a camo lightweight short sleeve. The wicking is pretty good, had my girlfriend spill some water on me while we were shed hunting and in about 15 minutes it was pretty much dry. Keep in mind of the neck, feels sort of like a half turtleneck took me awhile to get used to... Although, this does come in handy with pack straps and bino harnesses rubbing against your neck, prevents a rash. Superb benefit. It is very soft on the neck and I have yet to have it pull my neck beard. To sum things up, don't hesitate buying a couple, but if you are like me and get hot in almost all conditions, wait until they come out with a short sleeve.

Completing my system
Wore the shirt for my 1st time while turkey hunting and liked the product. Shirt wasnt as form fitting as I had hoped but Im on the lean side. Ordered pants today and hat came last week. Im hoping the pants fit well as to me its the most important. My only issue is that the hat was pretty big. I purchased the smallest one and a slight breeze took it right off my head. I am a 40 yr old 6ft 1 adult. I'm not a small guy and still the hat ran was too big. No other smaller option available. Worried to order the beenie now. I had my girl sew two small spots in the back to fit as I need it to complete the system. Good prices and received it promptly for free shipping. Products came within a week via ground.

Product Feedback - Tenacity
I like the shirt and it works well shedding sweat. I was also pleasantly surprised by the scent bag you included with my purchase. Pnuma products are a little pricy (though I like the guarantee). I will wear the heck out of it and see how it holds up over time.
I am very likely buy more of Pnuma's products as quality / wearability are very important to me.

Great shirt
I really like this shirt. Can't beat it for early season and also works great to layer for colder weather. Do yourself a favor and get yourself one. Thanks pnuma team.
