Resellr Intelligence Menswear — Edition #9

This Week's Menswear Briefing

The data is clear this week: summer menswear is moving fast. Across 575 listings tracked, the overall sell rate sits at 30.6% with an average sold price of £12.27. But the real story is in the category breakdown. Swimwear is leading the charge at a 57.1% sell rate and £10.88 average sold price, shifting in just 0.3 days. Shorts are close behind at 47.1% sell rate and £9.08 average. These are not slow burns. Resellers listing the right summer items are clearing stock before the week is out.

At brand level, Ralph Lauren is the standout performer. A 37.5% sell rate at £18.58 average sold price, with items gone in under half a day. That is strong margin territory. Polo Ralph Lauren in the hidden gem data is even more striking: 87.5% sell rate, 7 from 8 sold, at £17.28 average. If you are not actively picking Ralph Lauren polos and shorts from charity shops right now, you are leaving real money on the table. Budget up to £4 per item from charity shops and you are looking at a comfortable 3x to 4x return on the right pieces.

Nike and adidas are both performing solidly. Nike sits at 34.2% sell rate and £12.73 average sold, shifting in 0.8 days. Adidas edges ahead on sell rate at 41.9% with a £9.08 average, clearing in 0.7 days. For both brands, activewear and shorts are the formats to focus on given the item-type data. Gymshark is a hidden gem worth noting too: 80.0% sell rate, 4 from 5 sold, at £10.75 average. Gymshark mens training shorts and tops are easy to find in Facebook Marketplace bundles and car boots. Pay no more than £2 to £3 per item in a bundle.

Umbro deserves special attention this week. A 66.7% sell rate across 6 listings, with a £21.00 average sold price. That is the highest average of any hidden gem candidate. Umbro retro football shirts and training gear are having a genuine moment driven by football nostalgia and the upcoming summer tournament season. England fixtures will be dominating the calendar through June and July, and football heritage brands always spike in that window. Charity shops still undervalue Umbro badly. You should be paying £2 to £4 for shirts in good condition and listing them between £16 and £25 depending on the era and condition.

One area to approach carefully is Marks and Spencer. The data shows only a 10.0% sell rate at £5.00 average sold, with a listed average price of £9.97. That gap between listed and sold price tells you buyers are simply not biting at current asking prices. M&S menswear floods the charity shop rails and the competition on Vinted is fierce. Unless you find something truly distinctive, the time cost of listing M&S pieces is hard to justify against the returns. The North Face also needs careful handling. Listed prices are averaging £31.90 but the sell rate is only 30.0% at £8.00 average sold. That suggests overpricing is killing conversions. If you price North Face realistically you can move it, but most of the stock sitting unsold is priced for a market that does not exist.

Looking ahead through late June and into July, the opportunity is obvious. School sports days, summer holidays, festival season, and warm weekend weather all drive demand for lightweight menswear, activewear, and swimwear. Source swimwear, shorts, and branded sportswear now. Ralph Lauren polo shirts, adidas shorts, Nike training tops, Umbro football shirts, and Gymshark activewear are your priority picks. Hit charity shops mid-week when new donations come through, and keep an eye on Facebook Marketplace for bulk sportswear bundles. The sections below break down the hidden gems, brands to avoid, and a full sourcing guide for the biggest summer opportunity of the year.

Market Health

Summer menswear is accelerating sharply, with swimwear and shorts leading the market at 57.1% and 47.1% sell rates respectively and both clearing in under a day. The overall market sell rate of 30.6% across 575 listings is healthy, and the hidden gem tier is showing exceptional strength, particularly Polo Ralph Lauren at 87.5% sell rate and Umbro at £21.00 average sold price. The main drag on overall figures is slow-moving formal and knitwear stock, with knitwear at 18.5% sell rate and jeans and trousers at 17.1%, which are pulling the category average down despite strong performance in summer formats.

Seasonal Early Warning

England summer fixtures and the broader football calendar through June and July reliably spike demand for football shirts, training wear, and heritage sportswear brands. Combined with school holidays beginning in mid-July and British summer holiday travel, the menswear categories of swimwear, shorts, and branded activewear are heading into their strongest six-week window of the year. Source now while charity shop rails are still stocked and competition from other resellers is lower.

The Summer Menswear Playbook: Exactly Which Brands to Source in June for Maximum July Returns

Why June is the most important sourcing month in the menswear calendar

Most resellers make the mistake of sourcing for the current week. The resellers who build real consistent income source for the season that is four to six weeks away. Right now, in late May and early June, British charity shops and car boots are filling up with summer donations. Families are clearing out wardrobes ahead of holidays. Men are dropping off last year's holiday gear, old sportswear, and branded pieces they have outgrown. This is your window. By mid-July, every savvy reseller in the country will be competing for the same stock. Source now while the rails are full and the prices are still low. This week's data across 575 tracked Vinted UK menswear listings confirms the direction of travel. Swimwear is converting at 57.1% sell rate with a £10.88 average sold price. Shorts are at 47.1% sell rate. Activewear is at 50.0% sell rate. These are the item types to build your stock around for the next six weeks. Below is a brand-by-brand breakdown of exactly what to pick, what to pay, and how to list it.

Ralph Lauren and Polo Ralph Lauren: the crown jewel of June sourcing

Ralph Lauren is the top-performing brand in this week's data with a 37.5% sell rate and £18.58 average sold price, clearing in just 0.4 days. But the Polo Ralph Lauren sub-brand in the hidden gem data is even more compelling: 87.5% sell rate, 7 from 8 sold, at £17.28 average. This is the closest thing to a guaranteed sale you will find in menswear reselling. What to look for: Classic-fit cotton polo shirts in solid colours, particularly navy, white, pale blue, and racing green. Sizes M through to XL move fastest. Check the embroidered pony logo is intact and the collar is not fraying. Also look for Ralph Lauren swim shorts, chino shorts in pastel colours, and Oxford shirts in lighter fabrics. Avoid the heavier knitwear for now. What to pay: Up to £4 at a charity shop for a polo shirt in excellent condition. Up to £2 at a car boot. These should sell for £14 to £20 on Vinted depending on condition and colour. On swim shorts, pay up to £3 and list at £12 to £16. Listing tip: Always include the specific Polo Ralph Lauren pony logo placement in your photos. Buyers search for it and it immediately signals authenticity. Measure chest width and state it clearly in the description.

Umbro: the overlooked goldmine hiding in plain sight

Umbro posted a £21.00 average sold price this week with a 66.7% sell rate, making it the highest average sold price among all hidden gem candidates. The reason is simple: football nostalgia is enormous right now and Umbro is the original English football heritage brand. Club shirts, England training gear, and retro diamond-print items from the 1990s and early 2000s are selling to collectors and casual buyers alike. Charity shop volunteers consistently mislabel Umbro as generic sportswear and price it at £2 to £4. That is your advantage. A 1990s Umbro diamond-print training jacket in good condition can fetch £20 to £30 on Vinted. An England or club training shirt from the early 2000s can reach £18 to £25. What to look for: The double diamond logo on chest or sleeve. Older printed nylon training jackets in the classic colour-block style. Football shirts with club or England branding. Avoid modern Umbro pieces with minimal branding as they have little collector appeal. What to pay: £2 to £4 at charity shops, £1 to £3 at car boots. Target a minimum 5x return on any Umbro piece you pick.

Quick maths: Umbro sourcing scenario
Buy price: £3.00 at a charity shop. Vinted listing price: £20.00. Vinted seller fee (5% + 70p): £1.70. Royal Mail 2nd class large letter or small parcel: £2.80. Net profit: approximately £12.50. That is a 4x net return on your sourcing cost, and Umbro items are clearing in under a day based on current data.

Gymshark: the car boot bundle play

Gymshark mens activewear is showing an 80.0% sell rate at £10.75 average sold price. That is an outstanding conversion rate for a brand that regularly appears in Facebook Marketplace sportswear bundles at £10 to £20 for a bag of mixed items. The key with Gymshark is being selective. Training shorts, fitted tees in dark colours (black, grey, navy), and cycling shorts are the fastest movers. Older thick hoodies and zip-ups are slower and bulk up your postage costs without adding proportional value. Searching Facebook Marketplace for "mens sportswear bundle" in your local area will turn up Gymshark pieces mixed in with Nike, adidas, and Under Armour. If the bundle works out at £2 to £3 per item overall, any Gymshark pieces in good condition are essentially profit-generating. At £10.75 average sold price with a couple of pounds in fees and postage, you are clearing £6 to £7 net per item.

adidas and Nike: reliable volume stock

adidas posted a 41.9% sell rate at £9.08 average sold price this week, shifting in 0.7 days. Nike is at 34.2% sell rate and £12.73 average, clearing in 0.8 days. Neither brand is an exceptional margin play, but both offer reliable volume throughput when sourced correctly. For adidas, focus on training shorts, Originals graphic tees, and three-stripe tracksuits. The Originals range has stronger brand recognition and commands slightly higher prices than standard training gear. Avoid adidas football boots and anything that needs significant cleaning, as the margins disappear quickly. For Nike, condition is everything. The listed average this week was £16.96 but items are only selling at £12.73, which means anything less than very good condition will sit. Prioritise Nike dri-fit training tops, running shorts, and Tech Fleece pieces in dark colours. These have genuine demand through summer for running and gym use. Buy prices: Up to £3 for adidas shorts or tees at charity shops. Up to £4 for Nike training tops. Both brands are plentiful at car boots and often appear in Facebook Marketplace sportswear bundles.

Diesel: the undervalued denim and swimwear pick

Diesel posted a 60.0% sell rate at £8.00 average sold price this week. The brand feels dated to many charity shop volunteers, which means it is consistently underpriced on the rails at £2 to £4. For resellers, that creates a reliable low-risk sourcing opportunity. In summer, Diesel logo swim shorts are the priority. They carry real brand recognition with buyers in the 25 to 45 age range and typically list well at £10 to £14. Slim-fit jeans and straight-leg cuts in dark wash also sell steadily. Avoid heavily distressed or acid-washed styles as the market for those has shrunk considerably. Listing Diesel effectively means leading with the brand name prominently in the title, including the specific cut name if it is visible on the label, and photographing the leather back patch clearly. Diesel buyers are brand-aware and want to know exactly what they are getting.

Under Armour: the quiet overperformer

Under Armour posted the best sell rate of any major brand this week at 40.0% with an average sold price of £10.75 and items clearing in just 0.3 days. It is consistently undervalued by other resellers who focus on Nike and adidas, which means sourcing is easier and competition on Vinted is lower. Under Armour mens compression tops, training shorts, and heat-gear running tops are the items to prioritise. The brand's technical fabrics look good in photos and the performance-focused buyer base is less price-sensitive than casual fashion buyers. List at £9 to £14 for tops and shorts depending on condition. Pay up to £3 at charity shops.

How to structure your sourcing this week

A practical approach for the next fortnight: dedicate two charity shop visits mid-week when new donations are most likely to have been processed. Focus your rail time on the sportswear and casualwear sections first and work through in brand priority order. Ralph Lauren and Polo Ralph Lauren, then Umbro, then Gymshark if present, then Under Armour, then adidas and Nike. At car boots and in Facebook Marketplace bundles, look for sportswear bags and mixed activewear lots and apply the same priority order. For swimwear specifically, keep an eye on the beachwear sections of charity shops from now through July. Men's swim shorts in any of the above brands at under £3 are a fast, low-effort listing that converts well based on this week's 57.1% sell rate data. Next week we will be looking at exactly how to photograph and price menswear for maximum visibility in Vinted's summer search algorithm, including which title keywords are driving the most impressions on the fastest-moving brands right now.
