Women's Long Sleeve T-Shirt Boom
Excellent quality and how we
test it at UTOPY
Product quality is the foundation we build on. We value our customers and want to spare you the inconvenience of dealing with warranty claims.
That's why we take great care with quality checks, even if our methods are sometimes unconventional. We like to be sure.
Indestructible seams
Before putting a new product into production or introducing an improvement, we always make samples and put them through their paces. With leggings, we focus mainly on the seams. In practice, we stretch the leggings in every direction, then apply even more pressure to all the areas where the fabric is stitched together.

Original patterns We design our own patterns that you won't find anywhere else. Every piece is an original with its own distinctive style.

Digital printing We use modern printing techniques for lasting, vibrant colours. The patterns stay vivid even after many washes.

Production We sew our products in the Czech Republic with a focus on quality. Every piece passes through the hands of experienced seamstresses.
Product detailed description
Material
The women's Boom long-sleeved t-shirt is made from Drift fabric. Drift wicks away sweat, dries quickly and takes longer to develop odours during wear. It contains 93 % polyester microfibre and 7 % elastane, which gives the knit stretch to adapt to your movements and shape. The knit weighs approximately 150 g/m².
Fit and sizing
You'll find this t-shirt among UTOPY women's t-shirts in sizes XS–5XL. The cut sits closer to your body without being fully fitted; if you're between sizes, choose the larger size for a looser fit. You'll also find the design on BOOM leggings.
The print
This original UTOPY design features comic-book lettering, clouds and jagged speech bubbles with areas of red and white. The colour is sublimated directly into the fibres rather than forming a surface layer, so you won't feel the print when you wear it. The white, unprinted areas may be slightly see-through; the coloured, printed areas are opaque. The design is adjusted separately for each size to keep key details out of seams and from being hidden under a sleeve.
Care
Wash inside out at 30 °C without bleach or fabric softener, which can reduce performance and the fabric's ability to wick away moisture. Air dry without a tumble dryer. There's no need to iron after washing: the knit holds its shape, and with the recommended care, the colours stay vibrant even after years of wearing and washing.
