Long-Sleeve Underlayer Scrub Tops
Long-sleeve underlayer scrub tops are thin base layers cut close so they don’t bulk under a V-neck or crew top — built for cold operatories, refrigerated lab rooms, and 6am clinic opens. Same 72/21/7 fabric the rest of the LumiScrubs catalog uses, in core neutrals only.
Why every clinical wardrobe needs at least one underlayer
Cold operatories, refrigerated lab rooms, and 6am clinic opens are warmer with a thin long-sleeve under your scrub top. Most “thermal underlayers” you can buy off-the-shelf are either too thick (bulks under a V-neck and bunches at the armhole) or made of cotton that holds sweat all day. I built the Underlayer Long Sleeve thin enough to sit flat under the Essential V Top, Soft Crew Top, or Chairside Zip Top — same 72/21/7 polyester-rayon-spandex blend that breathes by mid-shift instead of trapping heat. Cut close at the wrist so the cuff doesn’t bunch at the sleeve hem of the outer top. Practical, not exciting, but the dental hygienists and vet techs who buy one usually come back for two more.

The underlayer plus the most common tops it pairs under:
- Underlayer Long Sleeve — the base layer. Thin, four-way stretch, sits flat under any LumiScrubs top.
- Essential V Top — common pairing for dental hygienists and chairside assistants in cold operatories.
- Soft Crew Top — common pairing for hygienists who want the crew silhouette over a V.
- Chairside Zip Top — common pairing for chairside dental assistants in fluid-contact roles.
Underlayer scrub questions
What is an underlayer scrub top?
An underlayer scrub top is a thin long-sleeve base layer worn under a regular scrub V-neck or crew top — for cold operatories, refrigerated lab rooms, or early-morning clinical opens. The LumiScrubs Underlayer Long Sleeve is cut close at the wrist and torso so it sits flat under any outer top without bulking the armhole or bunching at the sleeve hem.
Does the underlayer fit under all LumiScrubs tops?
Yes. The Underlayer Long Sleeve is designed to sit flat under every top in the LumiScrubs catalog — Essential V Top, Soft Crew Top, Chairside Zip Top, Front Desk Collar Top, Men’s Essential V Top, and the rest. It’s cut close enough that it doesn’t bulk the armhole or pull at the sleeve cap of the outer top.
What’s the underlayer made of?
Same 72% polyester / 21% rayon / 7% spandex blend the rest of the LumiScrubs catalog uses, just lighter weight for the underlayer role. That means four-way stretch through the shoulders and torso, breathability that keeps it from trapping heat by mid-shift, and the same color-locked palette so the underlayer matches across reorders. No water-repellent finish on the underlayer (it doesn’t see fluid contact under the outer top).
Can I wear the underlayer alone in warmer operatories?
Yes, but most clinical roles prefer to wear it as a base layer. Worn alone it reads more athletic than clinical — fine for a private practice with no patient interaction, less common in patient-facing roles. If you wear it alone, the regular care rules still apply (cold gentle wash, tumble dry low, no bleach).
How many underlayers should a clinical worker own?
1-3 depending on climate and operatory temperature. Northern-state dental hygienists and vet techs working cold operatories tend to run 3 underlayers in rotation (one on body, one in wash, one clean). Warmer-climate or central-air-controlled practices can run 1-2. The underlayer wears longer than the outer top because it doesn’t take direct fluid contact or surface abrasion.
Sizing for underlayer
The Underlayer Long Sleeve runs XS-3XL on a slightly closer block than the outer tops — designed to sit flat under the outer scrub, not as a standalone top. If you’re between sizes, size down for closer base-layer fit, size up if you prefer to wear it as a relaxed top on its own. Sleeve length runs regular; cuff sits at the wrist. Full sizing at the size guide.
Care
Wash cold inside-out on a gentle cycle, tumble dry low, no bleach or fabric softener. The underlayer takes wash cycles better than the outer tops because it doesn’t see surface abrasion. The 365-day quality guarantee covers seam splits, severe pilling, major color fade, and hardware failure on the underlayer the same as on the outer pieces.
The Underlayer Long Sleeve is the piece I never expected to be a repeat-purchase driver — but vet techs in cold operatories and dental hygienists running 6am opens keep adding them to reorders. I keep this collection narrow on purpose; underlayers in fashion colors weren’t worth the SKU complexity for the volume. — Saive
