Sumattory Hermida jersey

Summatory's Hermida jersey is made in Italy and designed in Spain and is designed for the warmer weather. It matches the bib shorts we tested recently, and if the orange doesn't do it for you, both are available with blue panels too.

The jersey has been designed in collaboration with World Champion mountain biker Jos Hermida, although there's nothing off-road specific about the design. Indeed, the reflective trim on one of the rear pockets is a whole lot more useful for riding on the road than for hooning through the woods.

The fabric is a nylon (72%) and elastane (28%) mix so it's mega-stretchy. It's a race/performance cut - slim to avoid any fluttering around in the breeze, that high elastane content meaning that it feels close-fitting rather than tight. The sleeves are similarly slender so they'll sit well on the average skinny-armed cyclist, although there's plenty of give to accommodate bigger guns too.

The neck is fairly low as cycling jerseys go. This isn't a jersey for keeping out chilly air; it's more concerned with getting cool air in. You get laser-cut perforations under each arm and along the centre of the back to improve ventilation, for example, and the full-length front zip provides plenty of scope for controlling the internal climate.

The fabric itself is soft on your skin. It's not as airy as some super-light mesh fabrics but it shifts sweat well and dries rapidly to keep you comfortable. I've never found myself feeling uncomfortably damp and clammy in this jersey. It has an SPF (sun protection factor) rating of 50+, by the way. Sumattory reckon it's suitable for riding in temperatures of 15-30C and I'd say that about covers it.

You get the obligatory three pockets in the lower back although they're each a different depth. Radical! The middle one is a generous 23cm, which is useful; store a pump in there and it's unlikely to escape. The right hand pocket comes with an extra zippered compartment for valuables too, the face closest to your body being waterproof. That means you can sling your mobile phone in there without the screen coming out foggy.

After just a few weeks it's hard to tell how the zip will standup to long-term use, but it looks good quality. The puller is large enough to grab easily even when you're moving at speed and it locks down with a healthy click to prevent any unwanted creepage. The silicone print inside the elasticated waistband works well too. There's not a lot of it but it holds the hem in place effectively.

Finally, a word on the sizing. I usually take either a medium or a large, depending on the brand. This one is a large and it's about as small as I'd like to go, so consider going for a size larger than usual.

And finally finally, the price. At £110, this is one of the more expensive short sleeve jerseys out there. The likes of Assos and De Marchi, for example, might have pricier options but this certainly ain't cheap. It's a really good jersey with some cool features but you'd struggle to make out a case for it being top value and so would I.

Verdict

Good performance jersey for the warmer weather, although it's expensive
