Sizing Guide

All Relentless Rise apparel is printed on premium Bella+Canvas and Next Level blanks. Measure twice, order once — here's everything you need.

How to Measure Yourself

📏
Chest
Wrap a tape measure around the fullest part of your chest, just under your armpits. Keep it level and snug but not tight.
📐
Length
Measure from the top of your shoulder at the base of the neck straight down to where you want the shirt to end.
💪
Sleeve
From the center back of your neck, over your shoulder and down to your wrist bone. Used for long sleeves and hoodies.
Pro tip: If you're between sizes, size up. Our blanks have a retail fit — not boxy, not tight. A size up gives you that premium, comfortable drape.

Unisex T-Shirts — Bella+Canvas 3001

Our most popular blank. Ring-spun cotton, retail fit, extremely soft. Measurements are garment measurements in inches — measure the shirt flat.

Men's Premium T-Shirts — Next Level 6210

Ultra-soft tri-blend fabric with a slim, athletic fit. Runs slightly slimmer than the Bella+Canvas 3001 — if you prefer a relaxed fit, size up one.

Fit note: Next Level 6210 runs about half a size slimmer than Bella+Canvas 3001. Athletic builds will love the true-to-size fit; if you carry weight in the chest or shoulders, size up.

Women's Relaxed T-Shirt — Bella+Canvas 6400

Fit note: The 6400 has a relaxed, slightly boxy silhouette — not oversized, just comfortable and effortless. If you want it to hug your frame, size down. If you love that easy, lived-in drape, order your normal size.
