About Summit Vial Heavyweight Tee
The Summit Vial tee keeps the front understated with a small North Summit Labs chest mark, then opens up across the back with an illustrated research vial set above a rugged mountain range.
It uses the same heavyweight, boxy-fit cotton blank as our other tees, with dropped shoulders and a relaxed body. Size up 1–2 sizes for a more oversized look.
Each tee is made to order and ships separately from peptide orders. Free-vial offers and sitewide promotional codes do not apply to apparel.
