Sasta Jero pants: first impressions

Sasta Jero pants come from a Finnish brand best known for making seriously tough kit for the sorts of activities and pastimes that Finns traditionally love – namely, hunting, fishing and general outdoors life. So, if your typical day might involve a morning spent foraging for chanterelles in the forest before whiling away an afternoon chopping firewood for the winter, Sasta Jero trousers are for you. Perhaps it’s no surprise that bushcraft legend Ray Mears loves ’em. 

They’re also made with sustainability in mind, since the main fabric is a polycotton blend of recycled polyester and organic cotton (for more on this subject see sustainable hiking clothes). This is pre-treated with PFC-free Nikwax water-repellent solution for added weather resistance. The trousers are reinforced at the knees and ankles with Kenytex panels for durability – a tough polyester fabric that incorporates Kevlar fibres (yes, the same stuff that is used to make bulletproof vests). That gives a clue as to just how durable these hiking pants are. A stretch gusset in the crotch also permits a little extra flexibility. 

Other features include articulated, pre-shaped knees, a large, zipped thigh pocket with a secondary press-stud storm flap and Velcro-adjustable tabs at the ankles and calves. Hidden lace hooks are fitted to allow you to attach them to hiking boots too. Keeping these trousers up is also a belt-and-braces affair – literally – since as well as being fitted with belt loops, they also have twin sets of buttons to fit braces. The waistband is semi-elasticated for a more forgiving and comfortable fit.

Sasta Jero pants: on the trails

These trousers are so rugged and well made that they would certainly function as field or even work pants as well as general outdoor wear. However, we’d say they’re best-suited to long woodland or moorland yomps, particularly if you’re venturing along little-trodden paths that might involve pushing though a fair bit of tangled heather, gorse, bracken and briar. 

The fact that they cinch in at the ankle and mid-calf allows for a neat and precise fit in the lower leg, preventing them from getting snagged or caught, while also keeping twigs and other debris out of your boots. 

They also do a decent job in more technical mountain terrain – they’re certainly tough enough – although bear in mind that the fabric doesn’t offer quite the same articulation as stretch softshell pants. 

Remarkably, given their burly construction, they’re neither overly stiff nor heavy, so they still provide good all-day comfort. There are no vents to help with airflow though, so on the warmest summer days we’d recommend switching to lighter trousers. Similarly, in winter you might want more weatherproof options – though these will happily fend off spring showers and autumn drizzle.
