Illuminate your ride with the Prism Alpha Geometric jersey, where vibrant colors meet cutting-edge performance. Inspired by the way light refracts through a prism, our Prism jersey features a spectrum of dynamic hues that shift and sparkle with every turn.
Our premium Alpha jerseys come in a race cut that is tailored to be highly form fitting, with shorter lengths and longer sleeves. The fabric with interwoven bamboo charcoal fibres was specially chosen for additional breathability and sweat wicking properties, keeping you cool and dry for all occasions. This allows for maximum aerodynamic effect with the greatest comfort for rides of all distances.
We recommend you pair this with our bib shorts for the full Pack experience!

We recommend following the same size as The Pack Jerseys, though do note that they will fit slightly differently - notably the front is shorter to accommodate for a less baggy fit when riding (vs standing).
The measured sizes may have a variance of about 1 centimetre. Do note that the sizing here refers to the actual measurement of the jersey and not your body size.
The material of the jersey also stretches, so please account for this in choosing your size. If you are between sizes, get a larger size for a looser fit or a smaller size for a more aero skin-tight fit. If you have questions about your sizing, please feel free to email us at sales@thepack.sg and we'll be happy to advise you!
Customer Reviews
Compared to previous jerseys I've worn in the past, these are some of the lightest I've seen so far. They're comfortable and great for Singapore weather, especially if you need them to dry quickly. The back pockets are a bit hard to access with one hand sometimes due to the cutting of the opening but it isn't a huge deal.
Nice thin and comfy material for Singapore weather. The batik print on the jersey is nice, make the jersey look classy.
Great improvement in terms of fit from the first version of the pack jerseys. The length was on point and the design is beautiful. Better than many more expansive brands out there. Highly recommended 👍🏻
I have used The Pack from the first version, which has always been promising and great for my weekend rides. Now with the Alpha series, it's better than ever. Catering for shorter rides without compromising comfort.
Sleek design meets all day riding comfort. Can't go wrong with this. Forget garbage rapha and PNS jerseys
