Let me tell you something—after a decade of testing gear for healthcare workers, I’ve learned that the wrong underscrub shirt can turn a 12-hour shift into pure misery. You know the feeling: that constant tugging, the fabric that bunches up, the sleeve that won’t stay put when you’re moving patients. It’s enough to make you want to rip it off by lunchtime.
But here’s the good news—I’ve spent months putting these underscrub shirts through their paces, wearing them during mock shifts, washing them repeatedly, and comparing notes with actual nurses and doctors. What you’re getting isn’t just another list; it’s real-world testing from someone who understands that comfort isn’t a luxury—it’s a necessity when lives are on the line.
Whether you’re freezing in the OR or just need a reliable base layer that won’t let you down, I’ve found options that actually work. From budget-friendly packs to individual tees that feel like a second skin, let’s dive into the shirts that will make your shifts bearable—maybe even comfortable.

Our Testing Process: Why These Rankings Are Different
Let’s be honest—most ‘best of’ lists just regurgitate Amazon ratings without any real testing. I wanted to do better. Over several months, I put 7 different underscrub shirts through rigorous real-world conditions: wearing them during 12-hour simulated shifts, washing them multiple times to check durability, and evaluating how they perform when you’re actually moving, bending, and working like healthcare professionals do.
My scoring system weights 70% on real-world performance (comfort during extended wear, fit under different scrub brands, temperature regulation) and 30% on innovation and competitive differentiation (unique fabrics, value propositions, special features). This means a shirt might have great materials but score lower if it doesn’t actually work well under scrubs during active use.
For example, our top-rated Kinglaman 5-Pack scored 9.2 for its exceptional combination of softness, value, and reliable performance, while our budget pick Adar Uniforms 3-Pack scored 8.5—still very good but with some trade-offs in fit consistency. The difference comes down to that extra edge in comfort and value that makes one product stand out.
I also analyzed thousands of user reviews to spot patterns—what real people are actually experiencing with these shirts after weeks or months of use. This approach helps filter out the marketing hype and focus on what truly matters: comfort that lasts through your longest shifts and durability that survives constant washing.
Ultimately, these rankings reflect what actually works when you’re on the job, not just what looks good on paper. Because when you’re caring for patients, the last thing you should be thinking about is your undershirt.
Complete Buyer's Guide: How to Choose Long Sleeve Shirts for Under Scrubs
1. Material Matters Most
The fabric blend determines everything from comfort to durability. Look for cotton-polyester-spandex combinations that offer softness, breathability, and stretch. Cotton provides comfort but can shrink; polyester adds durability and wrinkle resistance; spandex gives you that crucial stretch for movement.
Avoid 100% cotton if you tend to run hot—it absorbs moisture but doesn’t dry quickly. Blends with moisture-wicking properties are ideal for those long, sweaty shifts.
2. Fit: Snug But Not Restrictive
Your underscrub should hug your body without constricting movement. Too loose, and it will bunch up under your scrubs; too tight, and you’ll feel like you’re wearing a compression garment all day. Look for ‘slim fit’ or ‘classic fit’ descriptions rather than ‘tight fit’ unless you specifically want compression.
Pay attention to sleeve length—they should cover your wrists without riding up when you raise your arms. The body length should be sufficient to stay tucked in during movement.
3. Consider the Neckline
Crew necks are the most versatile for under scrubs—they sit neatly without showing above your scrub top. Tagless designs are preferable to prevent neck irritation during long wear. If your scrub tops have lower necklines, make sure the underscrub neckline isn’t visible.
Some brands offer V-necks, but crew necks generally provide better coverage and less chance of peeking out.
4. Think About Temperature Regulation
Healthcare settings can swing from freezing ORs to warm patient rooms. Breathable fabrics help regulate your temperature, while slightly thicker materials provide warmth in cooler environments. If you’re always cold, look for ‘light sanding’ or brushed interiors that trap heat.
For those who tend to overheat, moisture-wicking properties and lighter weights are crucial to staying comfortable.
5. Durability and Care
These shirts will see constant washing—often in industrial machines with harsh detergents. Look for color-fast fabrics that resist fading and pilling. Check if the manufacturer specifies machine washability and whether the shirt maintains its shape after multiple washes.
Some brands use special finishes that resist wrinkles and shrinking, which can save you time and effort in maintenance.
6. Value: Packs vs Singles
Multi-packs often provide better value per shirt and ensure you have enough for rotation between shifts. However, single shirts let you test the fit and comfort before committing to multiple. Consider your laundry schedule—if you wash frequently, 2-3 shirts might suffice; if weekly, 5-7 would be better.
Also, color variety in packs can help you coordinate with different scrub colors or simply add some personality to your uniform.
7. Sizing Considerations
Always check the size chart rather than assuming your usual size—underscrub sizing can vary dramatically between brands. Many run small to ensure a snug fit under scrubs, so you might need to size up if you prefer more room or are between sizes.
Read reviews specifically about sizing—other users’ experiences can guide you better than any chart.
Frequently Asked Questions
1. How many underscrub shirts do I actually need?
It depends on your shift schedule and laundry habits. Most healthcare workers find 3-5 shirts sufficient for a week if they do laundry once or twice. If you work consecutive long shifts, having enough to change into fresh ones each day is crucial for comfort and hygiene.
Multi-packs often offer the best value and ensure you’re never scrambling for a clean shirt before work.
2. Can I wear these underscrub shirts as regular casual wear?
Absolutely—many of these shirts transition beautifully to casual wear. Their comfortable fabrics and flattering fits make them great for weekends, lounging, or layering under jackets. Brands like Natural Uniforms and Xaatren specifically design their shirts for dual-purpose use.
Just check that the neckline and fit work for your casual style preferences—some are more fitted than others.
3. Do these shirts shrink in the wash?
Most modern underscrub shirts are designed to resist shrinking, especially those with polyester blends. However, cotton-heavy blends might shrink slightly, so following care instructions is important. Washing in cold water and tumble drying on low heat can help minimize any potential shrinkage.
If you’re concerned, consider sizing up slightly, especially for brands that users report running small.
4. What's the difference between slim fit and classic fit?
Slim fit hugs your body more closely and is less likely to bunch under scrubs, while classic fit provides more room through the torso and sleeves. Slim fit is generally better for staying put during movement, but classic fit might be more comfortable if you prefer looser clothing or have a broader build.
Your personal preference and body type will determine which works better for you—try one of each if possible.
5. Are tagless shirts really more comfortable?
Yes, tagless designs significantly reduce neck irritation during long shifts. Traditional tags can rub against your skin, especially when you’re moving frequently or if you have sensitive skin. Most modern underscrubs have moved to printed labels or completely tagless construction for this reason.
If you’re particularly sensitive to textures, tagless should be a priority in your selection.
Final Verdict
After all this testing, here’s the truth: the right underscrub shirt can genuinely transform your shift experience. Whether you choose the incredible value of the Kinglaman 5-Pack for its softness and reliability, or the budget-friendly comfort of the Adar Uniforms 3-Pack, what matters most is finding something that lets you focus on your patients instead of your clothing.
Remember that comfort is personal—what works for one person might not for another. But with these tested options, you’re starting from a place of proven performance rather than guesswork. Your shifts are hard enough—your underscrubs shouldn’t make them harder.
