661 Subgear Short Sleeve Compression Shirt Review
First ride with my 661 (sixsixone) Subgear (sub-gear) short sleeve compression shirt today. Made my order online so didn't get to try on the various sizes which range from XS-XL. I am 5 "10 and am on the broad size so I ordered the large but worried it would be too big until it showed up and I nearly had to ask my girlfriend to help me get it on and off- extremely snug fit. The short sleeve version of the subgear has the shoulder pads and the chest/sternum pad both of which are a much stiffer, more substantial compound that you would think. You can knock on the pad and will get the hard almost plastic compound sound and feel to it while closer evaluation reveals that it is indeed a firm memory foam design- this ended up boding well for rider comfort. The chest pad, as you likely suspected, is likely to be of little use unless you happen to huck yourself onto your chest or take an unsuspected tree-branch to the chest.
The subgear fit comfortably and easily under my baggy 3/4 sleeve jersey. Riding in winter pheonix weather ~80F the added combination was clearly warmer than riding jersey alone but not at all intolerable. The microfiber has a sweat wicking feature so with an airflow I actually felt a chill as it drew away the sweat. I didn't find the shoulder pads in any way hindered arm movement during aggressive trail riding and I quickly forgot I was even wearing the shirt.
Summary- the sixsixone subgear short sleeve jersey is the perfect addition to the arsenal for someone who is looking to add a little extra defense against shoulder (and possible chest?) injury during heavey AM or light downhill/FR/DJ riding. While incredibly hard to get on and off, the extra confidence one can gain knowing they are slightly less likely to acquire a compression injury to the shoulder can help you continue to push your limits on the trail.
