Under Armour Men’s Expanse Utility Jacket: Specs and Buying Guide

The Under Armour men’s Expanse Utility Jacket, style 6000882, is an insulated shirt-jacket with a snap front, a corduroy collar and UA Storm water repellency, listed at $180 in the US. This guide is based on the manufacturer’s published specifications and category standards rather than hands-on testing, so every detail below comes from Under Armour’s own product listing, a US retailer listing, or a cited study.

One thing to settle before anything else: this jacket is on its way out. Under Armour’s US product page for style 6000882 now returns a “Page Not Found” error, and the US retailers we checked show it sold out in every size. If you want one, you are shopping remaining stock, not a current-season item.

What Are the Under Armour Expanse Utility Jacket Specs?

Under Armour’s regional site still carries the full listing. According to Under Armour’s product page for the Expanse Utility jacket, as of October 2026, it has:

• Style number: 6000882
• Fabric: 65% polyester, 35% cotton woven twill
• Insulation: all-over 100g synthetic fill
• Water protection: UA Storm technology, using a fluorine-free water repellent treatment
• Closure: full-length centre front snaps
• Pockets: dual-entry secure hand pockets, a snap-closure exterior chest pocket and a drop-in interior chest pocket
• Details: textured corduroy collar, interior pocket and interior cuff lining, adjustable cuffs
• Fit: Regular, described by Under Armour as a classic fit
• Colours: Black on Under Armour’s own listing, plus Field Khaki and Washed Navy at US retailers

Under Armour sums up the design as “the water-resistance and light insulation of a jacket, with snap front closures and the finished look of a shirt.” In other words, it is a shirt jacket, or shacket, rather than a weatherproof shell.

What the listing does not give is a garment weight, a waterproof rating or a temperature range. That is normal for this category, but it means you cannot compare it on those numbers against a hardshell or a down jacket on paper.

How Much Does the Expanse Utility Jacket Cost?

The US list price is $180. A US retailer listing shows that price across Field Khaki and Washed Navy in sizes M through XXL, with every size marked sold out at the time of writing.

Because the jacket is being sold through rather than restocked, prices now move in two directions at once. Remaining retail stock often sits at full price, while clearance listings and marketplace sellers can be far cheaper. A reasonable approach is to decide what the jacket is worth to you before you search, then treat anything near $180 as the ceiling rather than the going rate.

Watch out for one thing when comparing listings. Prices on international Under Armour sites are in local currency, and a Canadian retailer we checked listed the same style at CAD 215. Confirm the currency and the style number, 6000882, before judging whether a price is a deal.

What Does “Fluorine-Free Water Repellent” Mean?

This is the most interesting line in the listing, and the one most buyers will skip. Under Armour states the jacket “uses a fluorine-free water repellent treatment.”

Durable water repellent, or DWR, finishes have historically relied on per- and polyfluoroalkyl substances, known as PFAS. The “fluoro” in that name is the point: PFAS are fluorinated compounds. A finish described as fluorine-free is therefore a claim that the repellent chemistry does not use PFAS.

That is not a small distinction. A 2022 study by Toxic-Free Future, “Toxic Convenience,” tested 60 products bought in autumn 2020, including 20 pieces of outdoor apparel. Of the 47 items marketed as stain or water-resistant, 34, or 72%, contained PFAS. None of the 13 items without that marketing appeared to contain any. The researchers also noted they found items marketed as water-resistant that appeared to be PFAS-free, which is the category this jacket’s listing places it in.

Regulation has since caught up in two large US markets. California’s AB 1817 and New York’s S.1322/A.994 both took effect on 1 January 2025, prohibiting apparel and textiles with intentionally added PFAS. A fluorine-free finish is what compliance looks like on a product page.

There is a trade-off worth knowing. Water repellency is a surface treatment on any jacket, fluorine-free or not, and it wears down with use and washing. When rain stops beading and starts soaking into the face fabric, the finish is tired rather than broken, and a wash-in or spray-on repellent made for the job can restore some of it.

Is the Expanse Utility Jacket Warm Enough for Winter?

It depends what you are asking it to do. The 100g synthetic insulation is a light to moderate fill, spread all over rather than concentrated in panels, and Under Armour’s own framing is “lightweight warmth without any excess bulk.”

On its specifications, that suits:

• Autumn and spring: as a standalone jacket in cool, dry or drizzly weather
• Mild winter days: worn over a hoodie or midlayer
• Everyday wear: errands, driving, walking the dog, casual work settings

It is a weaker choice for hard winter conditions, sustained rain or active outdoor use. Cotton absorbs water in a way polyester does not, so a cotton-blend shell holds more of it once the repellent finish is overwhelmed. There is also no hood, as the product images confirm, no sealed seams and no published waterproof rating. A common mistake with shackets is to treat them as a winter coat because they look substantial; this one is a layer, not a parka.

How Does It Fit, and What Else Is in the Expanse Utility Range?

Under Armour lists the fit as Regular, which the brand defines as “classic, right-down-the-middle fit: not too tight, not too loose.” The model shown on the listing is 185 cm, roughly 6 feet 1 inch, in a size large. Sizes run from SM to XXL.

Because this is a shirt jacket meant to go over a hoodie or midlayer, the usual advice applies: if you sit between sizes and plan to layer underneath, the larger size is the safer pick. Under Armour does not publish chest or length measurements for this style, so check the retailer’s size chart.

The jacket belongs to a wider Expanse Utility range, and the matching Expanse Utility cargo pants, style 6000883, are still listed on Under Armour’s US site at $130. They use a different build, 100% polyester ripstop with 4-way stretch, but share UA Storm and the same fluorine-free repellent treatment. If the jacket is sold out in your size, the pants are the part of the collection you can still buy new.

Who Is the Expanse Utility Jacket Best For?

On its published specifications, it suits someone who wants one good-looking layer for cool, damp weather and values the shirt-jacket look over outright weather protection. The pocket layout is the strong point: two secure hand pockets, an external chest pocket and an interior drop-in pocket.

It is a weaker fit if you need a hood, real rain protection, serious winter warmth, or a size that is already sold out. Given the discontinued status, it is also a poor choice if you want to be able to replace or re-buy it in a year.

Frequently Asked Questions

What is Under Armour style 6000882?

It is the men’s UA Expanse Utility Jacket, an insulated shirt jacket in 65% polyester and 35% cotton twill, with 100g synthetic insulation, a snap front, a corduroy collar and UA Storm water repellency.

Is the Under Armour Expanse Utility Jacket discontinued?

Under Armour’s US product page for style 6000882 now returns a “Page Not Found” error, and the US retailers we checked list it as sold out in every size, so it appears to be selling through rather than being restocked. Regional Under Armour sites still carry the listing.

Is the Expanse Utility Jacket waterproof?

No. Under Armour describes UA Storm as repelling water without sacrificing breathability, and publishes no waterproof rating or sealed-seam construction. It handles drizzle and light showers, not sustained rain.

Does the Expanse Utility Jacket contain PFAS?

Under Armour’s listing states the jacket uses a fluorine-free water repellent treatment. PFAS are fluorinated compounds, so a fluorine-free finish is a claim that the water repellency does not rely on them.

Is it true that all water-resistant jackets contain forever chemicals?

Not any more, though it was common. A 2022 Toxic-Free Future study found PFAS in 72% of the stain and water-resistant items it tested, but it also found water-resistant products that appeared to be PFAS-free. Bans in California and New York took effect on 1 January 2025, so new apparel sold there should not contain intentionally added PFAS.

How warm is 100g insulation?

It is a light to moderate fill suited to cool weather rather than hard winter cold. On this jacket, Under Armour positions it as lightweight warmth without bulk, which fits autumn, spring and mild winter days, usually over a midlayer when it is colder.

Final Thoughts

The Under Armour men’s Expanse Utility Jacket is a $180 insulated shirt jacket in polyester-cotton twill, with 100g fill, a corduroy collar, four pockets and a fluorine-free water repellent finish. That last detail is the one worth noticing, because it puts the jacket on the right side of the PFAS rules that took effect in 2025.

Buy it as a cool-weather layer rather than a winter coat or a rain jacket, size up if you plan to layer underneath, and move quickly if you find your size. With the US product page gone and retailers sold out, what is left on shelves is what there is.
