You've got somewhere between £75 and £175 to spend, you've settled on ASICS, and now you're stuck on the question that stops most people at the checkout: asics tracksuit vs set. In photos they look like the same buy in different weather. They are not.
Short version before the detail. A set is a matching top and bottom, tee or vest with shorts, £69.99 to £74.99. A tracksuit is a matching jacket or windrunner with full-length bottoms, £129.99 to £149.99. A tri-set is three pieces, £154.99 to £174.99. If you want the full lay of the land first, the complete UK buying guide to ASICS sets walks through the whole range.
This post is the decision itself. Cost per wear, how each one holds up across a British year, how many outfits it unlocks, what happens when you split the pieces up, and a straight answer at the end about which one to buy first.
Set, tracksuit or tri-set: what each one actually is
Tempo sells three shapes of ASICS Core kit. People confuse all three, so get the vocabulary straight and the rest of the decision gets easy.
- A set. Two matching pieces, a tee or a vest with woven shorts, in the same colourway, sold together and designed to be worn together straight out the bag. The ASICS Black Core T-Shirt Set is £74.99. The Smoke Grey colourway of the same set is £69.99.
- A tracksuit. Two matching pieces again, but it's a jacket or windrunner up top and full-length bottoms below. The ASICS Black Core Tracksuit sits at £149.99, and the Black Core Windrunner two-piece comes in cheaper at £129.99.
- A tri-set. Three pieces sold as one, typically a jacket, a top and a bottom. The Black Core Tracksuit Tri-Set is £174.99 (price correct at time of writing).
Watch the naming. The Black Core Windrunner Set has "set" in the title but it's a jacket and long bottoms, so it behaves like a tracksuit. Judge by the pieces in the bag, not the word on the label.
Everything sits together in the main ASICS collection. If you know you want long bottoms, go straight to the tracksuit range. If it's shorts you're after, the two-piece sets are the place to start.

Cost per wear: what each one really works out at
Sticker price is the wrong number. Cost per wear is the honest one, and it flips the order.
A £74.99 set gets worn in shorts weather and in the gym. Three or four wears a fortnight from May through September, plus training sessions the rest of the year, puts you past 40 wears in year one. Under £2 a wear, and it drops every summer after.
A £149.99 tracksuit covers a longer stretch of the calendar. Sixty wears is a conservative guess for anyone who dresses casually most days, so call it £2.50 a wear. Slightly more per outing, far more days on which it's a sensible thing to put on.
The tri-set reads expensive and isn't. £174.99 across three pieces is roughly £58 a piece, and each piece works on its own. Per garment, it's the cheapest way into ASICS Core.
Which one works harder across the year
Be honest about the weather where you live. Shorts weather in the UK is short. A set is excellent for maybe four months outdoors, then it becomes gym kit and holiday kit, which is not nothing, but it isn't daily wear either.
A tracksuit does the opposite. It's what you reach for on a grey Tuesday, over a tee for the school run, in the car, at the airport. The Steel Grey Core Windrunner Tracksuit at £149.99 gets worn most, because grey sits under a coat better than black and it doesn't look like you're off to training when you're not. If the windrunner shape is new to you, the breakdown of how the Core Windrunner works across sets and tri-sets is worth five minutes.
On days of use, the tracksuit wins. On intensity of use during the months it suits, the set wins. They peak at opposite ends of the calendar.
Splitting them up: how each one behaves as separates
This is where the money question gets settled, because a two-piece you only ever wear as a two-piece is a uniform, not a wardrobe.
Set pieces split well. The shorts go with any plain tee, and the top goes with jeans without looking like half of something. Add the Black Core T-Shirt on its own at £34.99 and you've a second top for the same shorts, which is the cheapest new outfit you'll ever buy.
Tracksuit pieces split even better, and the bottoms are the workhorse. A pair of Black Core Woven Pants at £54.99 goes with everything you own, and the Steel Grey pair at £39.99 is the better buy if you already have black. The jacket does the same job in reverse. The Black Core Windrunner as a standalone is £89.99 and goes over a hoodie, a tee or a shirt. Browse the joggers and woven pants if separates are how you shop, and the five-piece ASICS capsule wardrobe lays out which pieces cover the most ground.
The tri-set argument
If your budget stretches to £155 or more, the tri-set is hard to argue against. The jacket layers over the top, the top works alone in warmer weather, and the bottoms carry the whole thing through winter. That's a full fit plus two spares, from one order.
The Black Core Windrunner Tri-Set at £154.99 is the entry point. The Steel Grey Windrunner Tracksuit Tri-Set at £174.99 is the one to get if you want the colour that goes with the most trainers. Pair either with a set of Kayanos and the whole outfit is sorted in one go, which is the thinking behind the full fits edit.
Which to buy first if you're starting from zero
No ASICS in the wardrobe yet? Read down this list and stop at the first line that sounds like you.
- If you're buying in spring or summer and want it worn this week, buy a t-shirt set. The Maroon Core T-Shirt Set at £74.99 is the one people compliment.
- If you train four or more times a week, buy the Black Core Vest Set at £74.99. It lives in the gym bag.
- If you want one thing you'll wear from September to May, buy a tracksuit and make it black.
- If you already own decent joggers, skip the two-piece and buy the windrunner on its own.
- If you've got £155 or more, buy a tri-set. Nothing else at this price does as much.
- If you're between sizes or new to the brand, settle the fit first. The ASICS sizing guide against Nike and Under Armour will save you a return.
- If you're still comparing brands, the head to head on ASICS, Nike and Under Armour sets covers cut, price and feel.
Quick answers
Is an ASICS tracksuit better value than a set?
Per wear across a year, yes, because it suits more months. At the till, no, since a set is roughly half the price. Buy on when you'll wear it.
Can you wear a tracksuit to the gym?
Plenty do, but it's a warm-up and travel layer rather than training kit. A vest or tee set is the one you actually train in.
Is a tri-set just a tracksuit with an extra top?
In pieces, yes. In use it's more, because the third piece turns one look into several. Check the product page for exactly which three items are included.
Do I get free delivery on a set?
UK delivery is free over £100, so a set needs a second item alongside it to qualify. Tracksuits and tri-sets clear it on their own.
