Under Armour Gilets Resale Value

A used Under Armour gilet is typically worth £13 to £52 (approximately $17 to $69), against £12 to £50 for gilets generally. Under Armour is a technical apparel brand first, and its resale rests on whether the fabric still does its job. Compression kit that has lost its stretch is worth very little regardless of how it looks.

Seller-declared grades, sterling with an approximate US dollar equivalent at £1 ≈ $1.33 (July 2026). What each grade means.

What holds its value across Under Armour

HeatGear and ColdGear pieces with the stretch intact, which is the technology people are actually buying
Team and licensed kit, which has a following beyond ordinary sportswear
Larger sizes, which are consistently harder to find second hand than small ones
Outerwear and gilets, which cost more new and hold value better than base layers

What pulls Under Armour resale value down

Stretched-out compression garments, where the elastane has given and the fit has gone — which is the whole point of the product
Pilling on the smooth technical fabrics, which shows badly and cannot be removed without damaging the surface
Persistent odour in synthetic base layers, which holds in the fibres and is difficult to wash out completely
Cracked printed logos, which is how the graphics on technical fabric eventually fail

Identifying and dating yours

The interior label names the fabric technology, which is what buyers search for rather than the garment type
Stretch the garment and let it go on camera if you can, since recovery is the honest measure of whether it still works
Photograph the underarm and inner thigh areas, which are where pilling and thinning show first

What lifts any gilet, whatever the label

Gilets are judged on fill and zip, exactly like a jacket, but sell for less because they suit a narrower range of weather.

Down fill with good loft
Recognised outdoor and heritage brands
Working full-length zips
Intact baffles with no leaking fill

And what pulls one down

Clumped or migrated fill
Failed zips
Pinholes leaking down
Thin unbranded gilets

Working out what yours is worth

Shake it out and check the fill lofts evenly
Run the zip fully
Look for escaping feathers at the seams

What to state in the listing

Size, with chest measured flat
Fill type and fill power if stated
Whether it packs into its own pocket
Loft condition, and whether any seam is leaking fill

Brand, fill and size: “Rab Down Gilet, 700 Fill, Size M” or “Padded Gilet, Synthetic, Size 14”. Fill type and power are the searches for outdoor buyers. Say if it packs into its own pocket, which is a real feature people look for.

Preparing and photographing it

Establish whether it is down or synthetic fill, from the label, and note the fill power if given.
Check for down leaking through the seams, which indicates the baffles are failing.
Test the zip and check the loft by laying it flat — a gilet that has lost its loft has lost its warmth.

The label with fill type, size and composition
The zip and any leaking seam, stain or flattened panel

When it sells best, and handing it over

Lifts from September to February. Outdoor brands sell year round to walkers; fashion gilets are strongly seasonal.

Light and compressible, so postage is cheap. Do not store or post down heavily compressed for long periods, which damages the loft.

What buyers ask

How do I know if compression kit is worn out?

Stretch it and see whether it snaps back. If it stays loose the elastane has gone, and the garment no longer does what it was bought for.

Can odour be washed out of synthetic sportswear?

Sometimes, with a proper technical wash and no fabric softener. If it persists after that, say so — buyers would much rather know in advance.

How much is an Under Armour gilet worth?

Roughly £13 to £52 depending on condition, against £12 to £50 for gilets generally. The identification points above are what move a listing to the top of that range.

What the fees would take elsewhere

At the mid-range £32 for an Under Armour gilet, against what the commission marketplaces would deduct:

Platform	Fee	You keep
Poshmark	−£6	£26
eBay	−£4	£28
Mercari	−£3	£29
Etsy	−£2	£30
WishThrift	−£0	£32

Seller-side rates verified 26 Jul 2026, percentages only — the per-order and processing charges those platforms add are excluded, so the real gap is wider.
