Fasthouse’s Alloy Block jerseys are their range-topping technical riding T-shirts and come in both long and short sleeve versions. I prefer the long-sleeve option but both sleeve lengths are aesthetically bold and feature-packed technical mountain bike jerseys that perform great out on the trail.
Design and specification
Fasthouse uses two different weights of stretchy 'Dri' fabric across the jersey, the front and arms use a heavier weight, while a lighter weight Dri fabric is used under the arms and across the full back panel to help heat escape. The lightweight material is also used on the cuffs of the long sleeve and collar which has a shallow overlapping V-cut shape.
The stitching is overlocked and the cut of the jersey is designed to give a slim athletic fit to keep flapping to a minimum. There is a shallow drop tail to give full back coverage when you're in a riding position. On the rear left-hand side there is a small zipped pocket for valuables. Fasthouse has added a few reflective graphic elements on the rear for some extra visibility.
I found the sizing of the medium size to be good, the athletic fit gives a slim, flap-free fit. I found there was a little bunching around the shoulders on the short sleeve jersey but there is enough stretch in the material that it didn't restrict my movements at all. The arms on the long sleeve jersey are a good length although they will be very slim on burlier armed riders.
The materials feel good against the skin and the material drys quickly to help keep you comfortable. The lighter material helps reduce heat build-up too so they can be worn across a wider range of temperatures.
I'm not really sure what the rear pocket is actually for. You can't put anything heavy in it like a multi-tool or phone as it will flap and pull the jersey to the side as there is no structure to support it. You can squeeze a set of sunglasses in there but they are a bit lumpy and it's too much of a faff for stashing gloves. I'm sure some riders will find a use for it but I would happily live without it.
Whether you're looking for long or short sleeves, the Fasthouse Alloy Block is a very comfortable, slim-fitting jersey that's great out on the trail. Attention to detail around fabric paneling is well thought out, as is the addition of reflective detailing and a dropped tail. I don't know what the pocket is for but it doesn't affect the performance of the jersey if you don't use it. The moto graphics might not be for everyone, however, Fasthouse does offer loads of different colors and designs to choose from.
