Craft has been outfitting professional athletes since 1977, yet despite a strong reputation in technical running and trail gear, the brand had never had a dedicated review on RunMorph. The Pro Trail Singlet 2 is the singlet that best captures this Swedish approach: no gimmicks, just a very light fabric built to dump heat on hot mountain runs. At RunMorph, we looked at what this minimalist piece is really worth against the established competition.

Craft, the Swedish brand missing from the RunMorph catalog
Craft has been outfitting elite athletes since 1977 around one simple principle: the three-layer system, where each layer has a specific job in moving sweat away and regulating body temperature. The Swedish brand built a solid reputation in running, trail, cross-country skiing and cycling, but it was completely absent from the RunMorph review catalog. The Pro Trail Singlet 2 fills that gap with a product that sums up the brand's DNA: no frills, just a technical fabric built for a single goal, keeping you dry while you work hard.
This singlet is the updated version of the original Pro Trail Singlet, which already weighed in at a featherlight 83 g or so. Version 2 keeps that philosophy and switches to a recycled polyester jacquard jersey, a move in line with the outdoor apparel industry's environmental direction.

Jacquard jersey and side slits: what difference do they make on the trail?
The ultralight jacquard jersey on the Pro Trail Singlet 2 relies on a knit structure that keeps air moving without compromising how the garment holds its shape. The side slits exist for a specific reason: on a singlet, the hips are often where the cut restricts your stride on climbs or technical descents. By opening them slightly, Craft adds range of motion without widening the whole cut, which keeps the singlet close to the body.
The bonded hems at the neckline, armholes and bottom replace conventional seams in those spots, which are known to irritate the skin on long runs when a backpack or running vest rubs constantly.
The field test: what independent feedback confirms
RunMorph tip: save this singlet for hot runs of more than an hour, where its breathability really makes a difference. For winter or cool runs, pair it with a base layer instead, as we recommend for the On Race Singlet 2.
An independent field test carried out specifically on this singlet reports great freedom of movement and good sweat management: the garment dried quickly during the test run, with no moisture-related chafing, often the deciding factor for a singlet worn directly against the skin. That feedback covers the 83 g version of the Pro Trail Singlet, the direct predecessor of the current model. The technical construction (jacquard jersey, fitted cut, back ventilation) belongs to the same product family, but we haven't found any field test dedicated specifically to version 2 so far. We're stating that caveat openly rather than hiding it.
An additional test covering the Pro Trail range as a whole (T-shirt and shorts tested on a 13 km run with 885 m of elevation gain) confirms the line's technical consistency. The ripstop fabric on the front holds up well to abrasion from vegetation, the woven stretch mesh on the back ventilates effectively even in high heat, and the silicone inserts on the shoulders keep the backpack from slipping while you run. This test doesn't cover the singlet itself but pieces from the same technical collection, with the same material choices: a sign of consistency rather than direct proof, and worth taking for exactly that.

Craft Pro Trail Singlet 2 vs On Race Singlet 2: the comparison
| Criterion | Craft Pro Trail Singlet 2 | On Race Singlet 2 |
|---|
| Main use | Trail running, long hot runs | Road and trail racing |
| Material | Recycled jacquard jersey 86/14 | Technical DryTec fabric |
| Fit | Regular fit | Fitted racing cut |
| Details | Side slits, bonded hems | Race-focused construction |
| Price positioning | Around €40 | Premium positioning |
Both singlets chase a similar goal, staying light and breathable, but their philosophies differ. The Craft is a versatile training piece built to last on long runs, while the On Race Singlet 2 leans harder into racing. Your choice comes down to use: long days on the trail for one, race day for the other.
Pros and cons
ProsUltralight, breathable jersey, confirmed by independent tests on the same construction. Side slits that free up your stride. Bonded hems that limit irritation under a backpack. Recycled material, in line with the industry's environmental direction.
ConsNo field test found for version 2 specifically, a caveat to keep in mind. Regular rather than fitted cut, less suited to runners who want support. Upper-middle price for a plain singlet with no compression technology.

How to fit the Pro Trail Singlet 2 into your RunMorph training plan
This singlet earns its place on the summer long runs of your trail build, when managing heat becomes a performance factor in its own right. In a marathon build in hot conditions, it works just as well as in the mountains: what matters is how long you're out there, not the terrain.
👉 To build a season that mixes hot easy runs and long runs, lean on the RunMorph training plans and dress for the day's weather rather than out of habit.
RunMorph Coach verdict
The Pro Trail Singlet 2 does what you expect from a technical singlet: it breathes, it dries fast, it doesn't chafe. It revolutionizes nothing, and its regular cut won't suit runners who want a snug hold, but it's an honest, well-built product at a price that stays in the market average. 7.5/10: a good entry point into a solid brand, without being the must-have benchmark in its segment.
