Great question—there are a few common names, depending on the closure:

• Zip-up hoodie: A hoodie with a full front zipper for easy on/off and airflow.
• Button-front hoodie (or snap-front hoodie): A sweatshirt-style hoodie that closes with buttons or snaps.
• Hooded cardigan (sometimes called a cardigan sweatshirt): A softer, sweater-like open front layer that may have buttons and a hood.

If you’re choosing between them, consider how you’ll wear it. Zips and snaps tend to be quicker and sporty; button-front and cardigan styles lean more casual and cozy. Checking fabric weight, pocket style, and ribbed cuffs can also help you find the feel you want.

“Good” value varies by material, construction, and features rather than a single number. To assess value, consider:

• Fabric and weight: Midweight fleece or cotton blends often feel softer and last longer than ultra-light knits.
• Construction: Look for sturdy seams, quality zippers/snaps, and a reinforced placket on buttoned styles.
• Features: Warm linings, adjustable hoods, and roomy pockets can add utility.
• Fit and versatility: Oversized vs. regular fit, and whether it layers well across seasons.
• Care needs: Easy-care, machine-washable pieces may reduce long-term costs.
• Reviews: Feedback on softness, durability, and true-to-size fit can provide context.

Balancing these factors with your budget can help you decide whether a hoodie offers fair value.

You’ll see a few names for buttoned styles—each with a slightly different vibe:

• Henley sweatshirt: A pullover with a short button placket (often two to four buttons) at the neck.
• Snap-button sweatshirt: Similar to a Henley or full front, but using snaps for quick closure.
• Button-front cardigan sweatshirt: A sweatshirt-knit layer with a full button closure, cardigan-style; some have hoods.
• Shacket: A shirt-jacket hybrid (often flannel or fleece-backed) with a button front; sometimes hooded.
• Quarter- or half-button pullover: A fleece or sweatshirt with a partial button or snap placket for easy ventilation.

Choose based on how you’ll layer: Henleys and quarter-button styles are great under coats, while button-front and shackets feel more jacket-like.

That triangle at the neckline is commonly called a V-insert or V-gusset (sometimes nicknamed a “dorito”).

• Original purpose: Early athletic sweatshirts used a ribbed V to add stretch, help the collar keep its shape, and absorb sweat.
• Modern role: On many styles today, it’s mostly a design detail that nods to vintage sportswear, though it can still offer a bit of structure.

If you like the look, search for “V-insert” or “gusset” in product descriptions. To help the neckline keep its shape over time, drying on low heat or laying flat can be gentler than high-heat drying.

You’ve got a few practical options that can work for buttoned sweatshirts and hoodies:

• Check for spares: Some garments include extra buttons in a small bag near the tag.
• Match the hardware: Note size, color, and finish. For snaps, match the cap diameter and style (ring, solid, or logo cap).
• Use a repair kit: Snap kits (with a hand tool or pliers) and basic sewing kits make home fixes straightforward.
• Reinforce the area: Add a small backing fabric or extra stitches if the placket is worn.
• Professional help: A local tailor or alteration service can handle tricky snaps or thick fabrics.

After repairs, gentle washing and low heat can help preserve the new hardware.
