What You Need to Know
You just copped that limited AMP drop, but when you try it on, the fit is off. The shoulders bunch, the sleeves run long, or the torso is too boxy. If you have an athletic build or a slim frame, standard unisex sizing can leave you frustrated. This guide is for AMP fans who want their merch to look as good as they feel. By the end, you'll know exactly which pieces to choose and how to adjust them for a custom fit. We'll cover the AMP merch for athletic body type specifically, from hoodies to tees, and share insider tricks to get that perfect silhouette.
Step-by-Step Guide
Step 1: Know Your Measurements
Start by measuring your chest, shoulders, and torso length using a soft tape. For an athletic build, your shoulders might be 4-6 inches wider than your waist. For slim builds, your chest and waist are closer in size. Compare these numbers to the AMP size chart. Most AMP tees have a standard chest measurement of 20-21 inches for a medium, but if your shoulders measure 22 inches, go up a size.
Step 2: Choose the Right Silhouette
AMP offers two main cuts: standard and slim. For broad shoulders and a tapered waist, the standard cut in a size L fits the shoulders while the extra fabric can be adjusted. For slim frames, the slim cut in your true size avoids ballooning. Pro tip: Avoid oversized cuts if you're slim; they can make you look smaller.
Step 3: Pick the Best Hoodies for Athletic Builds
For athletic builds, the AMP Heavyweight Hoodie is a must. Its 12-oz fleece has a structured shoulder that doesn't sag. Size up to XL if you need room in the chest, then use the ribbed cuffs to keep sleeves in place. For tall frames, the Tall sizes add 2 inches in length without widening the body.
Step 4: Select Tees for a Slim Lean Fit
For a slim fit, go for the AMP Performance Tee in your true size. It has a 6.5-oz fabric with slight stretch that hugs without being tight. Avoid the classic logo tee if you want a slimmer look, as it has a straight cut. If you're between sizes, size down and stretch the shoulders gently.
Step 5: Taper and Tailor Your Shirts
If a tee fits the chest but flares at the waist, take it to a tailor. A simple side seam taper costs around $10-15 and removes 1-2 inches per side. For hoodies, tapering the sleeves can prevent that bell-bottom look. I've done this on three of my AMP hoodies, and the results are night and day.
Step 6: Account for Shrinkage
AMP's 100% cotton items can shrink 3-5% in the first wash. Buy one size up if you plan to machine wash hot. For pre-shrunk options, look for the AMP Heathered line, which uses a cotton-poly blend that stays consistent.
Step 7: Test with a Sample
Before buying multiples, order one T-shirt in your estimated size. Wash and dry it, then assess the fit. Retain the receipt so you can exchange if needed. I always recommend buying two sizes in the same design if it's a limited drop.
Step 8: Layer Smartly
For athletic builds that want layering flexibility, the AMP Lightweight Pullover (7-oz) is better than the heavyweight for wearing under a jacket. Slim builds can layer the AMP Tank Top under a flannel without bulk.
Common Mistakes to Avoid
- Choosing the wrong size based on the model: The model on site is often 6'1" and wears a medium. If you're 5'10" with broad shoulders, a medium will be too short. Always use the size chart.
- Ignoring sleeve length: For tall frames, sleeves on standard tees can ride up. Look for AMP's "Tall" variants that add 1.5 inches to sleeves.
- Drying high heat: Cotton AMP hoodies can lose up to 2 inches in length if dried on high. Use low heat or air dry.
- Buying oversized for a slouchy look: If you're slim, oversized can make you look like you're wearing a tent. Instead, go with a slim fit and layer.
- Not accounting for post-wash shrinkage: Always buy one size up for 100% cotton, even if it feels loose initially.
Pro Tips from the Community
- The Cold Water Fix: Wash all AMP merch in cold water, then hang dry. This reduces shrinkage to under 2% and preserves color. Many fans swear this keeps the fit perfect for years.
- The Shoulder Roll: If a tee shoulders poke out, do a quick "shoulder roll" by stretching the seam forward and back while damp. This relaxes the fabric and softens the line.
- Layer a Tank Under: For athletic builds, wearing an AMP Tank Top under a slightly baggy tee fills out the chest and creates a smoother silhouette. It's a cheap way to fix a boxy fit.
- Use a Tailor for Hems: The AMP vintage shirt has a folded hem that can be shortened easily. A $10 hem job on a 5-pack of tees transforms them into perfect cropped fits.
Recommended Gear & Products
