Summer Base Layers

With the summer season finally here, we can look forward to those long and humid Sunday rides. With temperatures reaching up too and beyond 30 degree weather, why would anymore want to layer up under their jersey? Base layers are no longer just an article worn during the colder temperatures, summer base layers are more of a body temperature regulator keeping the rider cool and comfortable. The layer of clothing directly in contact with the rider’s skin helps the body’s natural defences against overheating. The fabrics main purpose is facilitate homeostasis (heat regulation) with adequate moisture management during exercise in hot and humid conditions, wicking away sweat this helps regulate the body’s temperature.

 Comparing a base layer to temperature regulator, the two are very different. The temperature regulator will be manufactured from very thin and breathable materials such as yarn or polyester offering a comfortable and snug fit. The fit should be on the snug side to ensure the material is pressing against particular areas of the body to help wick away sweat and increase airflow and breathability. One of the main purposes of the regulator is simple; keep sweat off the body, keeping the rider comfortable well into the ride. 

 Choosing the correct jersey and bibs will play an important roll on keeping you cool and comfortable on the bike. On the days that are more hot and humid, it only makes sense to choose a light and thin jersey, most likely with mesh panels along the back, shoulders, or sides. The thinner the jersey, the more venerable the rider is to sunburns. The temperature regulator will offer a UV protection while still offering airflow. Bibs will play an important roll, best to choose bibs with thin and a mess strap allowing less material so the base layer can perform to its full potential. 

One brand that offers a wide range of base layers for all year is Assos. Assos Offers base layers for the coldest temperatures to offering a wide range of summer base layers. Assos Skinfoil line offers summer base layers that are sleeve less, short sleeve, to the full long sleeve. Some may ask why a full long sleeve can be worn in such hot conditions. The full sleeve will allow cooling, breathability but more importantly protection for the UV rays. Sunscreen can wear off over the ride, but a long sleeve will protect against the sun hours into the ride. Other brands such as Castelli and CHPT3 offer summer base layers that work great, but also incorporate unique styles and colours to complete that look you are after. Many cyclist do invest good money into the sport, we all know we want to look good while doing so. In conclusion, with the current cuts, fabrics, and styles is it justifiable to have a base layer in even the most hot and humid conditions? We here at Racer Sportif would definitely say yes. 

Keep cool & ride strong,
