1 Year Warranty
We guarantee that our shirts will repel stains that are caused by water-based fluids and semi-fluids. If stains are caused by oil-based fluids, such as skin oils or greasy food, the product will need to be washed or cleaned with stain remover.
We test the stain repellency for 30 washes at 30 degrees with ironing after each wash and no tumble-drying or bleaching. A lot depends on the type of machine, washing program, and detergent used, which is why we are not comfortable extending the guarantee above 30 washes for the stain repellency. Since the products needs significantly less washing than a traditional cotton product 30 washes will give you a lot of wears.
We guarantee that our shirts will repel odour caused by bacteria, such as odour from sweat. Our shirts will not repel odour from smoke or cooking. Due to the many different variations and levels of perspiration we unfortunately cannot guarantee a specific amount of days the products will last before odour starts being absorbed into the fabric. We know that our current customers wear it 3,5 days. But we guarantee that the anti-bacterial treatment will be active for 100 washes and hence block more odour than traditional cotton products for 100 washes.
The testing method used to determine wrinkling is called the "Durable Press rating". Our casual shirts are tested at a DP rating of 3.0 and the wrinkle-free shirts at a DP rating of 3.5, which is the commonly accepted definition of "wrinkle-free" fabrics. There is however always limitations when one choose natural products made of 100% cotton. The wrinkle-resistance is guaranteed for 30 washes, which is in line with industry standards from brands like Eton and Suitsupply.
We guarantee that our casual and business shirts will not shrink more than 2%, and that our t-shirts will not shrink more than 5%. These are industry standards for knitted and woven cotton garments.
We guarantee that our t-shirts absorbs fluids on the inside, which will not show on the outside. This effect works on "normal" conditions, but we cannot guarantee that sweat stains will be 100% blocked since it's still 100% cotton products and not a raincoat. Our products might seem like they work well for sports, but they are fashion products designed for everyday life and our guarantees hence only extends towards what we call "everyday usage". If you are considering to use the t-shirts for sports then please also be aware that we use heavy fabrics, which makes it warmer than a synthetic jersey. This effect will also gradually go down after every wash and will last 30 washes.
While our t-shirts block sweat by absorbing it into the inside of the fabric, our business and casual shirts are woven and we have not found a way yet to apply moisture-wicking technology to them. Our shirts to block moderate amounts of sweat, but if we made it 100% hydrophobic the sweat would stay on the body and hence not be comfortable in a warm or humid environment. So for the shirts our guarantee is that it blocks perspiration better than a traditional shirt and it dries up faster, but the t-shirts have a true significant difference compared to normal t-shirts.
DISCLAIMER: The white t-shirts are less good at hiding sweat stains then the other colours. This is due to the fact that the white fabric is more transparent, so even though the t-shirt is dry on the outside, the sweat on the inside is still visible. We are working hard to fix this and the next generation of t-shirts will perform better on this front.
We guarantee that the stain repellency will last for 30 washes and the odour repellency for 100 washes.
Keep in mind that you have to wash LABFRESH shirts less, so it’s still a lot of wears.
