Scrubs are designed for utility, not warmth or modesty. That thin poly-cotton shell leaves you shivering in a cold exam room, clinging to your skin after a long shift, and feeling exposed when you bend down to check a patient. Your scrub top wasn’t made to handle those moments — it needs a dedicated layer underneath that wicks sweat, hides lines, and keeps you comfortable from the first round to the final note.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve spent years analyzing medical apparel standards and reviewing how fabric blends, necklines, and seam construction impact shift-long comfort for healthcare professionals.
After combing through customer feedback and spec sheets on five leading models, I’ve identified the strongest contenders for the undershirts for scrubs category — each built to solve the specific problems nurses, doctors, and techs face on the floor.
How To Choose The Best Undershirts For Scrubs
Not all undershirts work under scrubs. A bulky cotton tee will add visible lines and trap heat. You need a layer that disappears under your uniform while managing moisture and temperature across a 12-hour shift. Here are the critical factors to evaluate.
Neckline and Collar Fit
A crew neck that sits too high will peek out above your V-neck scrub top and look sloppy. A V-neck that plunges too low leaves your chest exposed. Look for an underscrub whose collar sits just below the scrub neckline — the Cherokee WW700 crew is cut to ride higher but fits neatly under most men’s scrub tops, while the Natural Uniforms V-neck is designed specifically for women’s standard V-neck scrubs.
Fabric Weight and Stretch
The best underscrub fabrics balance warmth with breathability. A 180–200 GSM jersey knit gives enough heft to block cold air from air conditioning without feeling like a blanket. Look for a four-way stretch blend (typically polyester/spandex or polyester/cotton/spandex) that moves with you during bending, stretching, and lifting. Compression-style tops like the TELALEO offer a snug fit that stays tucked, while a relaxed cut like the Ekouaer gives you more freedom if you prefer a looser layer.
Durability Against Frequent Washing
Hospital-grade laundry cycles are brutal. Undershirts that pill, shrink, or fade within a month waste money. Prioritize double-stitched seams, pre-shrunk fabric treatment, and colors that resist chlorine bleach. Multiple verified reviews on all five products in this guide specifically praise their ability to hold shape and color after repeated washes.

In‑Depth Reviews
1. COZYFIT 3 Pack Underscrub Long Sleeve Women
The COZYFIT 3 Pack has quickly earned a reputation among nurses as the softest underscrub available. Customers repeatedly use the phrase “buttery soft” in reviews, and the four-way stretch jersey knit delivers a plush feel against the skin without adding visible lines under your scrub top. The fabric weight hits a sweet spot — substantial enough for chilly morning rounds but light enough for summer shifts.
Multiple buyers above 200 pounds report that the 2XL fits comfortably without squeezing, thanks to the generous stretch. The material is opaque even in lighter colors like gray, washing well with no pilling or shrinkage after several cycles. A few reviewers note that the sleeves run long, and the overall fit is slightly oversized — sizing down is recommended if you prefer a more fitted layer.
The three-pack configuration at this premium tier provides exceptional value per shirt when you factor in the fabric quality and construction durability. For nurses who spend 12+ hours on their feet, this undershirt’s combination of softness, breathability, and temperature regulation makes it the most well-rounded option in this guide.
Why it’s great
- Extremely soft four-way stretch knit
- Opaque fabric holds up well after washing
- True-to-size or slightly oversized fit works for various body types
Good to know
- Sleeves may be long for shorter arms
- Runs large — sizing down recommended for a snug fit
2. Cherokee Scrubs Men’s Long Sleeve Underscrub Knit Tee WW700
The Cherokee WW700 is the reference standard for men’s underscrubs — it has been in production since 2017 and the design hasn’t needed to change. The heavyweight knit feels substantial without being stiff, and the crew neck sits high enough to stay visible under most scrub V-necks. Multiple nurse reviewers confirm it layers perfectly under Cherokee and Dickies scrub tops without bunching.
Sizing is the dominant topic in customer feedback: the shirt runs a full size large. A man who normally wears a large should order a medium for a proper fit. The navy color matches standard navy scrubs exactly, and the fabric has shown zero shrinkage or fading after repeated hospital-grade wash cycles. One nurse noted the sleeves stay rolled up when pushed, a small but critical detail for tasks requiring bare forearms.
Female nurses looking for a more relaxed fit have also purchased the WW700 in smaller sizes, though the men’s cut is broader through the shoulders. If you want a warmer, heavier layer that prioritizes durability over stretchiness, this is the most proven choice on the list.
Why it’s great
- Proven durability after years of production
- Heavyweight knit blocks cold without overheating
- Navy color matches most scrubs perfectly
Good to know
- Runs one full size too large — size down
- Heavier feel than typical athletic baselayers
3. Natural Uniforms Women’s Under Scrub Tee V-Neck 3-Pack
Natural Uniforms designed this V-neck specifically for female healthcare workers who need a layer that sits completely below the scrub collar. The V-neck cut is shallow enough to remain hidden under standard V-neck scrub tops, solving the common annoyance of a crew neck peeking out. The fabric blend is soft and breathable, offering warmth without bulk — exactly what medical professionals want under a scrub top.
An important sizing quirk appears in customer feedback: the black shirts in the three-pack run smaller than white or other colors. Multiple buyers report that a black medium fits like a small, while the white medium fits true to size. If you plan to order this pack, consider sizing up if the black shirt matters to you. The white shirt is opaque enough to wear under light-colored scrubs without showing through.
Overall durability is strong — buyers report no pilling, shrinkage, or color fading after many washes. The stitching is clean and the seams have held up well. For nurses who prefer a V-neck for modesty and a cleaner neckline, this is the most reliable choice in the mid-range tier.
Why it’s great
- V-neck stays fully hidden under scrub tops
- Soft, breathable fabric with good durability
- White is opaque and not see-through
Good to know
- Black color runs one size smaller than white
- Fit is more relaxed with less compression
4. Ekouaer Womens 3 Pack Long Sleeve Shirts Crew Neck Underscrubs
The Ekouaer 3 Pack delivers a fabric feel that reviewers describe as “buttery soft” — nearly identical to the COZYFIT but at a lower tier. The crew neck is fitted without being restrictive, and the stretchy material hugs the body without squeezing. Buyers consistently mention that the shirts hold their shape after washing and the colors remain rich without fading.
The beige option leans more toward an ivory/almond shade than a true beige, so plan your color coordination accordingly. The 5% spandex content provides enough give for full range of motion during patient care, but the fit is compressive enough to stay tucked into scrub pants all day. One buyer noted the shirts are not see-through, which is critical for modesty under light-colored scrubs.
Customer feedback is nearly universally positive across multiple sizes. The value here is strong: three high-quality fitted tops at a price point that competes with single shirts from premium athletic brands. For those who prioritize softness and a snug fit without wanting to pay premium-tier prices, this is the best mid-range option.
Why it’s great
- Extremely soft, comfortable fabric
- Fitted compression without being restrictive
- Good color variety with opaque material
Good to know
- Beige reads more ivory/almond than true beige
- Compression fit — size up if you prefer relaxed layering
5. TELALEO 4 Pack Women’s Compression Shirt Performance Baselayer
The TELALEO 4 Pack is the budget-friendly compression option on this list, offering four shirts (black and white, short and long sleeve) at a competitive single-unit price. The fabric is lightweight and breathable, designed for athletic performance — it wicks moisture effectively and regulates temperature well during active shifts. Multiple buyers bought these for their daughters to wear under basketball jerseys, proving the compression fit works for high-motion scenarios.
Reviews consistently point out that the material is “tight without feeling suffocating,” which is the sweet spot for a compression baselayer. However, the fabric is thinner than the other options in this guide, and some users noted that the sides can feel slightly loose after repeated wear. One resourceful buyer sewed the arm pit seams for a tighter fit, indicating the construction isn’t as premium as higher-tier options.
The sizing runs true to the chart, but several buyers recommend ordering down if you want maximum compression for athletic use. For healthcare workers who want a lightweight, breathable layer that stays tucked and doesn’t overheat, this pack delivers solid value — just don’t expect the same plush hand feel as the COZYFIT or Ekouaer.
Why it’s great
- Great value — 4 shirts for a single-shirt price
- Lightweight, breathable compression fabric
- Moisture-wicking performance during active use
Good to know
- Fabric is thinner and less plush than premium options
- Side seams may loosen with extended wear

Final Thoughts: The Verdict

If you want a heavier, proven men’s crew neck, grab the Cherokee WW700. And for the best budget value in a compression baselayer, nothing beats the TELALEO 4 Pack.
