Hiyo Hoodie Sizing: How to Pick the Right Fit Before You Order

Quick answer

The 'in the spirit' hoodie is cut with a relaxed fit and is designed to be true to size, so start with your normal top size. If you want a clean, everyday look, stay true to size; if you want a noticeably oversized, streetwear-style drape, size up one. Because Hiyo does not publish a numeric chest or length chart for this hoodie, your most reliable move is to measure a hoodie you already like and compare it to Hiyo's stated fit and return policy before ordering.

Hoodie sizing is where most online orders go wrong, and it is rarely about the number on the tag. It is about how the fabric drapes, where the shoulder seam lands, and whether you want the garment to look intentional or borrowed. The 'in the spirit' hoodie is a relaxed, midweight cotton-blend piece with a specific construction that changes how it sits on the body, so it is worth understanding before you click buy.

This guide walks through how the hoodie is actually built, how to translate that into a size decision, and when a different Hiyo piece might serve you better. There is no published measurement chart to lean on here, so we will be honest about that limitation and show you how to work around it.

What the construction tells you about fit

The 'in the spirit' hoodie is made from an 80% cotton / 20% combed cotton blend in a 3-fleece, high-stitch fabric, and it is described as midweight. That combination matters for sizing: midweight fleece holds its shape better than thin terry, so a relaxed cut stays relaxed instead of collapsing. High-stitch fabric also tends to feel denser and a little more structured, which means the hoodie will not stretch out into a shapeless sack the way looser knits can.

It also has side seams and ribbed cuffs and bottom band, and it is made with no drawstrings. Side seams are a quiet fit signal: they give the body a defined line rather than a tubular shape, so the hoodie reads as relaxed but not boxy. The ribbed bottom band is the piece that decides your silhouette, because it pulls the hem in and creates that slight blouson over the waist.

• Midweight 3-fleece fabric holds structure, so a relaxed fit stays relaxed rather than sagging.
• Side seams give the body a defined line instead of a straight tube.
• No drawstrings means the hood opening is fixed, so the neckline fit is set by the size you choose.

How to measure a hoodie you already own

Since Hiyo does not publish a numeric size chart for the 'in the spirit' hoodie, the most accurate method is comparison. Take a hoodie you already wear and like, lay it flat on a bed, and smooth out the wrinkles. Measure across the chest from one underarm seam to the other, then measure from the highest point of the shoulder down to the hem. Write both numbers down.

Next, measure the shoulder width from seam to seam across the back. These three numbers are what actually determine whether a hoodie feels right. Chest width controls how much room you have to layer; body length controls whether the hem sits at your waist or below it; shoulder width controls whether the seams sit on your shoulder bone or drop down your arm.

• Measure a hoodie you already own rather than your body, since garment measurements are what you are comparing.
• Note whether your reference hoodie is regular or oversized so you know which direction you are adjusting.
• If your reference hoodie has a ribbed hem like the 'in the spirit' hoodie, your comparison will be more accurate.

Regular vs oversized: deciding on purpose

The 'in the spirit' hoodie is already described as having a relaxed fit, which means the baseline is roomier than a slim-cut sweatshirt. If you want the hoodie to look like a normal, well-fitting layer over a tee, order your usual size. This is the right call if you plan to wear it with jeans, under a jacket, or anywhere you want a clean line rather than a statement.

Size up one if you want the oversized look: dropped shoulders, sleeves that cover part of your hand, and a hem that sits lower over the hip. Be aware of the trade-off. Sizing up also widens the neck opening, and because there are no drawstrings to cinch it, an oversized fit can feel loose around the collar. If a snug neckline matters to you, stay true to size.

• True to size: relaxed but intentional, best for layering under jackets and everyday wear.
• Size up one: dropped shoulder, longer sleeve, lower hem, and a looser collar opening.
• If you are between sizes and want a regular look, take the smaller size; the relaxed cut already provides extra room.

Layering and climate considerations

Because the hoodie is midweight rather than heavy, it works as a mid-layer without adding bulk. If you plan to wear it over a thick flannel or a heavyweight tee, that extra bulk eats into the interior room of the hoodie, so sizing up can help. If you mostly wear it over a thin tee or on its own, your usual size will be comfortable.

The ribbed bottom band also affects how the hoodie behaves when you move. It keeps the hem anchored, so the garment does not ride up when you reach overhead. That makes true-to-size a good choice for active days, while a sized-up hoodie is better for lounging, travel, and the deliberately slouchy look.

• Layer over thick garments: consider sizing up for interior room.
• Wear on its own or over a thin tee: your usual size is the safer pick.
• Ribbed hem keeps the hoodie in place during movement, which favors a closer fit for active use.

If the hoodie is not the right piece for you

Not everyone wants a pullover. If you need a full-zip layer, an adjustable hood, or a lighter weight for warm weather, the 'in the spirit' hoodie is not the answer, and no amount of sizing adjustment will fix that. Hiyo also makes a 'window' staple tee in 100% combed cotton with a regular fit, which is a better starting point if you want a simple, pre-shrunk layer rather than fleece.

For cooler days when you want structure and pockets, the 'never wasted' sweatpants pair well with the hoodie as a matched set, and they are cut true to size with a drawstring waistband. If you are building an outfit rather than buying a single piece, thinking about the set together helps you avoid ending up with a hoodie that is roomier or tighter than the bottoms you wear it with.

• Want a zip or adjustable hood: this pullover is not the right style, regardless of size.
• Want a lighter warm-weather layer: the 'window' staple tee is a better fit for that job.
• Building a set: check that your hoodie and sweatpants sizes give you a consistent silhouette.

Decision rules: pick your size in three checks

• Rule 1: Default to true to size: The 'in the spirit' hoodie is designed with a relaxed fit and is intended to be true to size. If you want a normal, everyday layer that works over a tee and under a jacket, order your usual size. Checkpoint: if you are unsure and want a safe, versatile fit, this is the rule to follow.
• Rule 2: Size up only for a deliberate oversized look: Size up one if you want dropped shoulders, longer sleeves, and a lower hem. Accept the trade-off: the collar opening will be wider because there are no drawstrings to tighten it. Checkpoint: if a loose neckline bothers you, do not size up.
• Rule 3: Measure before you commit: Hiyo does not publish a numeric chest or length chart for this hoodie. Measure a hoodie you already like and compare it to the stated relaxed fit and true-to-size guidance, then review the return policy before ordering. Checkpoint: no measurement chart means your own comparison is the most reliable data you have.

Product facts that affect your size decision

• in the spirit hoodie: 80% cotton / 20% combed cotton, 3-fleece, high-stitch fabric, midweight, with a relaxed fit, side seaming, ribbed cuffs and bottom band, and no drawstrings. The midweight, high-stitch fleece holds its shape, so the relaxed cut stays intentional rather than stretching out. The ribbed hem anchors the fit, and the lack of drawstrings means the collar opening is set by your size, which is the main reason to think twice before sizing up.
• never wasted sweatpants: 80% organic cotton / 20% recycled polyester fleece, double-stitched, drawstring waistband, hidden zippered pocket inside the left pocket, true to size. If you are matching the hoodie with sweatpants, these are cut true to size, so use them as your baseline. The drawstring waistband gives you adjustability that the hoodie does not have, which means a slightly roomier hoodie can still work with a true-to-size bottom.
• window staple tee: 100% combed cotton, regular fit, neck ribbing, side seams, double-stitched hems, pre-shrunk. A useful comparison point: this tee is a regular fit rather than relaxed, so if you want a closer, more standard silhouette, the tee is the better choice. Its pre-shrunk cotton also means less size guessing than an unwashed fleece.

Who this hoodie fits best

Best for

• Shoppers who want a relaxed, midweight pullover that layers cleanly over a tee
• Anyone who prefers a structured fleece that holds its shape instead of stretching out
• Buyers who want a true-to-size fit and do not want to gamble on sizing up

Not for

• Shoppers who need a full-zip hoodie or an adjustable drawstring hood
• Anyone who wants a close, slim-fitting sweatshirt rather than a relaxed cut
• Buyers who require a published numeric size chart before ordering

Getting the 'in the spirit' hoodie right comes down to one decision: true to size for a relaxed everyday layer, or one size up for a deliberate oversized drape. Because Hiyo does not publish a numeric chart for this piece, measure a hoodie you already own and compare it to the stated relaxed fit, then check the return policy so you can order with confidence.
