Ten Thousand Men's Clothing

Frequently Asked Questions

• What size and fit should I expect from Ten Thousand shirts, and how should I choose between sizes?

  Ten Thousand shirts are designed to be fitted but non‑restrictive and are offered in XS–XXL; many pieces run slightly large for taller builds, so taller athletes often keep their usual size while shorter or slimmer users may find a boxier fit. Check the product-specific size chart and measurements for chest and length, and consider sizing down if you prefer a trim gym fit or if you’re between sizes.
• Which Ten Thousand pieces are best for heavy lifting versus HIIT, running, or rucking?

  For heavy lifting and barbell work, the Rep Shirt (50% cotton/43% polyester/7% spandex, ~190 GSM) provides a thicker, more durable feel that holds up to frequent loading. The Interval Shirt is optimized for HIIT and running with breathability and stretch, while Session Shorts are featherlight for speed, and Tactical Shirts/Shorts use abrasion‑resistant, moisture‑wicking fabrics built for rucking and backcountry use.
• How does the Rep Shirt compare to the Interval Shirt?

  The Rep Shirt uses a heavier 190 GSM cotton‑blend that emphasizes durability and structure for lifters, while the Interval Shirt prioritizes breathability and stretch for high‑intensity and endurance work. Fit differs as well: the Rep feels substantial and stable for barbell sessions, whereas the Interval can run large on some body types and offers a sportier, more mobile cut. Both are athlete‑tested but cater to different training priorities.
• What materials and construction features contribute to Ten Thousand’s durability?

  Durability comes from mid‑weight cotton/poly/spandex blends (like the Rep Shirt), flat‑lock seams to reduce chafing, reinforced panels in Tactical styles, and abrasion‑resistant fabrics in shorts and outer layers. Additional tech includes anti‑odor silver‑ion treatments, 3M Easy Care stain resistance on select styles, and a design focus on longevity without PFAS coatings.
• How should I choose between Session Shorts and Tactical Shorts, and which inseam is right?

  Choose Session Shorts for speed and running—lightweight fabrics and minimal bulk—and Tactical Shorts for rucking or outdoor durability, which add functional pockets and reinforced materials. Pick a shorter inseam for faster running and a longer inseam for heavy rucking or carrying loads; both lines offer precise fits and multiple inseam options, so match inseam length to your stride and activity.
