WHAT TYPE OF MATERIAL DO YOU USE? Our t-shirts are the very best quality, and all certified by The Fair Labor Association. The material used is 100 percent cotton. Men's t-Shirts are 195gms (white) and 200gm (colours). Women's are 160gms. The men's shirts are all pre-shrunk. Men's t-shirts are straight cut. The neckline is not too high or thick, and makes for a comfortable wear. Sizes L and XL are wide rather than long, so tall people should check the measurements below to see which size is right for them. Women's t-shirts are softer, with a cut that comes in over the middle and widens over the hips for a flattering cut. They have cap sleeves to fit the shoulders tightly. We've included UK dress sizes but these vary wildly depending on where you shop - so it's best to use the measurements below. Our hoodies are 280gms in an 80/20% cotton/polyester mix (this is a high cotton content for hoodies). They're a slightly slimmer profile which means a great flattering cut. They are: Unisex design, so suitable for both men, women, and older children. Check the sizes below. Features include: • Kangaroo pouch pocket • Double fabric hood • Pull cords through the neck are the same colour as the hoodie • Ribbed cuff and hem • Worldwide Responsible Apparel Production (WRAP) certified production • Twin needle stitching & detailing
