Description

Design-wise, sometimes the little details make the biggest difference. From the ‘scuba hood’ for front neck protection to the raglan sleeve for added mobility, the B1 Performance Hoodie is the ultimate base layer. The reimagined hood fits easily under a hard hat or helmet and the built-in UV protection keeps your skin safe from getting scorched by the sun, as well as comfortable and dry in other weather conditions.

A relentless sun hoodie for relentless heat. UPF 50+ protection you don’t have to reapply—designed to layer, built to resist abrasion, and cut to keep moving.

TW Abrasion Tear Resistant

Abrasion Resistant

Our B1 fabric is engineered to strike the ideal balance—lightweight and breathable, yet tough enough for the jobsite. Pick and snag resistant, it outperforms standard sun shirts when it comes to handling the daily wear and tear of real work.

Sun Protection

Woven for breathability and built to last, this shirt delivers UPF 50+ sun protection that’s embedded in the fabric, so it won’t wash out or wear off. Just dependable, all-day coverage made to handle harsh rays and harder days.

TW Four Way Stretch

Four Way Stretch

The B1 Sun Hoodie is built on a highly flexible interlock-knit fabric engineered for full mobility that stretches both side-to-side and up-and-down to move with your body, not against it. Plus, compared to cotton, it recovers quickly, and won’t tear even when yanked or stretched.

Reviews

Great lightweight shirt

"I do a lot of indoor/outdoor work and burn easy. This shirt is awesome to wear in the summer. Possibly the ‘coolest’ shirt I own and I don’t have to worry about getting burnt. Seriously though…I think this shirt keeps you cooler than any tshirt because the sun can’t get to you and any sweat you have (if there is the slightest breeze) actively cools you down."

— Nathaniel C. (5/5)

HiViz Yellow not so HiViz after 1 Summer

"I own both the Sage and hivis yellow. Hoodies are very comfortable and dry quickly. I needed the hivis for my job and even though following directions on washing they faded, lost their intense yellow coloring. For the price I would have expected color to last longer than 1 summer. The sage color hoodies have no issues with fading."

— Brian (2/5)

Comfortable Protection

"I'm at high risk for skin cancer and often need to work outside. The Northeast summers are getting hotter, and my skin is feeling it. A sun hoodie is a must-have for me, and this one fits better than the others I tried (true to size) and is comfortable to work in. The elastic hood is a nice touch. Thumb holes might be a nice addition—other options I tried offered those."

— Brian S. (5/5)

Takes one to B1

"These feel great! I have been using them on cool (75 degree) days in full sun with no issues. I am still getting used to the scuba hood, but the hood is light enough to wear a hat under or over it. I have liked being able to work covered uop without roasting and not stripping off an 1/8" of sunscreen at the end of the day."

— Jordan W. (5/5)

Love the TrueWerk style!

"The shirt fits comfortably and looks great when I am working outside. I get complements on the shirt all the time. Comfort for any type weather! Everything I have from TrueWerk is the truth! 😀"

— RONNIE C. (5/5)

Great fabric, tight cut

"Great lightweight fabric perfect for sun shade only complaint is the cut if the shirt is "slim" and hood edge is on the stiff side."

— Joshua C. (4/5)

Worth the money

"Absolutely perfect. T1 Sun Hoodie and T1 werkpant come in clutch in the summer heat. Got 3 pants and 2 shirts for work. Definitely buying more."

— Eliseo (5/5)

Super light weight, great for wearing in the sun as only shirt, stay cool, great sweat wicking technology.

Truewerk B1 Sun Hoodie

"The Truewerk B1 Sun Hoodie has become one of my go‑to work layers. As a city water operator, I’m in the sun all day, and this hoodie does exactly what it’s built for — keeps the hot sun off me without making me overheat. The fabric is lightweight, breathable, and comfortable enough to wear for long shifts. The hood design gives good neck and ear coverage, and it moves well without feeling restrictive. I enjoy wearing it so much that I’m already thinking about picking up another one. For anyone working outdoors, especially in heat and high UV, it’s a solid piece of gear that actually performs the way it claims."

— Sava K. (5/5)

Q&A

Can you screen print company logos on these?
Hi Jeremy, Yes, you sure can! Please consult with your choice embroiderer to ensure quality satisfaction. Thank you, TRUEWERK
Would the B1 be ideal for working in 80 degrees plus in constant sun and heat? I work in the pool and spa industry and am in direct sunlight for extended periods. I need the protection but not any added heat.
Hello Michael, Yes! B1 is going to be ideal for warmer weather. Here's some info on how our Layering System works. Layering TRUEWERK workwear is simple. Products that start with B are base layers, followed by M for mid layers, and S for shell layers. Each product in our workwear is followed by a number. The bigger the number, the warmer the piece. Base Layer As the foundation of our integrated workwear system, our base layers are worn next-to-skin and feature four-way stretch for maximum mobility while pulling moisture away from your body to keep you comfortable and dry. Mid-Layer Transitional mid layers insulate without adding extra weight or bulk, allowing you to easily adjust your gear throughout the day to match any fluctuations in temperature or conditions. Shell Layer TRUEWERK shell layers feature highly water- and tear-resistant softshell fabric to protect you from the elements and job site hazards. Our outermost layers offer extreme stretch for a full range of motion and let moisture evaporate without letting more in, ensuring you remain dry and comfortable.
