Q36.5 Base Layer 1 Sleeveless Info

The Q36.5 Base Layer 1 Sleeveless is a seamless cycling base layer for warm-weather riding, made in Italy. Q36.5 describes it as its "technologically extreme vision of the traditional seamless base layer," and it is built to add as little volume as possible under a jersey while moving sweat away from the skin.

The garment is knitted on Karl Mayer seamless machines using multiple integrated yarn structures at varying densities. Q36.5 says this pulls sweat from the skin toward the outer layer, where it can evaporate. The front follows the curves of the torso for fit and moisture management, and the back is thinner so excess heat can escape. The mesh creates a small gap between skin and jersey, which Q36.5 says gives a cooling effect. The tubular construction has no side seams, which Q36.5 says gives greater elasticity and less resistance to movement.

Fabric and weight

The base layer is 44% polyamide, 44% polypropylene and 12% elastane. Q36.5 lists its weight at 75 g in size M. The brand's Body Temperature Stability Guarantee for this garment is +22°C, which points to warm conditions and not cool shoulder-season rides.

Sizing

Sizes run XXS-XS, S-M and L-XL, which Q36.5 sizes by height and weight: S-M covers 155 to 178 cm (5 ft 1 in to 5 ft 10 in) and 58 to 78 kg (128 to 172 lb), and L-XL covers 175 to 190 cm (5 ft 9 in to 6 ft 3 in) and 78 to 100 kg (172 to 220 lb). It is meant to sit close to the skin. Q36.5's own reviewers describe it as very elastic and close-fitting, and one suggests sizing down, so riders between sizes should check the full chart.

The Base Layer 1 Sleeveless suits road riders who want an almost weightless layer under a jersey for hot days, long summer rides and races.

The RA Perspective

This is the base layer for hot days. Q36.5 builds it as a seamless knit with a thinner back panel, a body-mapped front, and a stated 75 g weight in size M. Their own stability rating is +22°C, so treat it as a warm-weather piece. If your rides start cold, it is not the layer for that.

It is meant to fit close. Q36.5's reviewers call it very elastic and snug, and one suggests sizing down, so check the height and weight chart instead of assuming your usual size. One reviewer also notes that the neckline can show above a lower-cut jersey, which is worth thinking about if you ride in an open-collar kit.

We would reach for it for summer road rides, long days where a jersey would otherwise sit directly on sweaty skin, and races where you want as little bulk as possible.
