CO  CO Cotton is in and thus it is one of the most widely used fabrics in the world, your wardrobe no doubt knows something about it. Cotton is a natural fiber, easy to wash and clean. It has good absorption properties and it is very pleasant to the touch. It tends to crease easily and that is why blends of cotton and polyester or cotton blended with elastane are so popular, as they make the cotton clothing more flexible and close-fitting.
In the collection LOAP, you will mainly find cotton in clothing - e.g. sweatshirts, T-shirts, shorts, dresses etc.
Feathers  Peri


Feathers an isolantion infill from quality duck feathers with high thermal protection which guarantees a perfect thermo insulation properties with low weight clothing. For quilting products we recommend gentle washing with a ball and the subsequent use of a dryer. This will secure a backward even distribution of the filling. Chemical cleaning is also possible, due to this, the filling remains in the original place for all the time.


EA  EA Elastane is clearly the superhero of flexibility. It can be stretched up to seven times its original shape and length. Elastane fibers are very delicate and are always used in combination with other fibers. E.g. cotton T-shirts with elastane will fit you better due to their elasticity, but they also tend to crease much less. Elastane fiber is resistant to seawater.

In the collection LOAP, you will find elastane especially in clothing - trousers, sweatshirts and T-shirts.
Ethylene vinyl acetate EVA EVA is great and we like it. It is an almost indestructible foam material. EVA likes swimming, it is lightweight and versatile - suitable both for a swim and a walk around the city. Shoes from EVA absorb shock very well and you can never drown them.

In the collection LOAP, you will find EVA in footwear - flip-flops, slippers and low shoes.
 Dural  Dural Dural is durable! It is a high-strength aluminium alloy, hard and long lasting. It stands out for its low weight. Due to the higher price it is mainly used in expensive tourist tents.

In the collection LOAP, you will find dural in the structure of some tents.
 Duralwrap Durawrap_1 Duralwrap is tuned laminate and you will enjoy setting up a tent with it.  Stakes from duralwrap can be identified according to the distinctive diamond-shaped pattern. Duralwrap material is more expensive than traditional fiberglass, on the other hand it offers a greater strength of rods with the same weight. The surface of the rods is also wrapped by tubing and the rods ends are fitted with metal couplings.

In the collection LOAP, you will see duralwrap in the structure of tents.
 Polyamide PA We root for polyamide. It is even better than cotton - it has better tensile strength, but it is also more flexible and more resistant to abrasion and tearing. Products made of polyamide do not shrink and they dry quickly. Their disadvantage is less resistance to the effects of light (they get yellowish in time) and easy charging with static electricity. Polyamide is often used to reinforce highly loaded places In mixtures with other materials.

In the collection LOAP, you will see polyamide especially in jackets (technology STORMEX) outer parts of shoes (technology TRIFIBRE), socks, backpacks and bags or sleeping bags.
Phylon PH Phylon is an ultra lightweight soft material, which inherently and brilliantly dampens any schocks. It is essentially a lighter and more durable, more moldable and double-molded EVA liner. The disadvantage compared to EVA is a higher price. Phylon is mainly used in midsoles and outsoles.

You will find Phylon in footwear in the collection LOAP.
Polyethylene PE Polyethylene is currently one the most widely used synthetic fibers in the world. For example many foils, toys, freezer bags and textile fibers are made from it. It is lightweight but extremely strong, it can withstand sunlight, weathering and humidity, it has good insulating properties. An improper storage of products may cause deformation or warping over time.

In this collection, you will find LOAP polyethylene especially in tent floors.
Polyethylene vinyl acetate PEVA EVA is almost half lighter material than PVC, but it also more resistant to lower temperatures. It is cheaper and recyclable material. PEVA is most commonly used for shower curtains and raincoats.

The collection LOAP includes PEVA in accessories  - for example in children's raincoats.
PL/PES  PL Polyester produced from oil is among the most widely used synthetic materials in the world. It is used to make e.g. PET bottles, underwear, as well as seat belts and sportswear. PES is a lightweight material, which does not absorb water, it leads sweat away from the body very quickly and dries well. Moreover, it is resistant to stains e.g. from sweat. PES is great because it virtually does not crease. The disadvantage is that it absorbs odors. Polyester is easy to maintain, but be careful when machine washing - the water temperature must not exceed 30°C. If you want to iron, you can do it only through a wet towel at max. 150°C. In this collection, you will find LOAP polyester in sports jackets (technology STORMEX, AQUA PRO, TSS), fleece sweatshirts (technology TECHFLEECE +) and functional underwear (technology TRIFIBRE), backpacks (technology BULLTECH), tents and sleeping bags (technology POLYPLUS).
Polypropylene PP Polypropylene wins in the flyweight category. With its low weight, it is the lightest fiber on the market. Polypropylene is stable and tough material, which has the lowest water absorption of all known textile fibers and quickly removes moisture from the body. Polypropylene has also excellent thermal insulation properties, and moreover, it does not shrink during machine washing even at higher temperatures.

In the collection LOAP, you will find polypropylene in socks.
Polyurethane PU Polyurethane is one of the best thermal insulators, moreover, it is very lightweight, it has good tensile strength and it resists the wind perfectly. Therefore it is perfectly suited as a membrane for functional clothing and footwear.
In the collection LOAP, you will find polyurethane in sports jackets (technologies DRYTECH, AQUA PRO, TSS), gloves, outer parts of boots and  belts, backpacks in (technology BULLTECH).
Polyvinyl chloride PVC_1 PVC is the third most widely used plastic on Earth and it is made from common salt. PVC is used to make e.g. toys, flooring, and also clothing and shoes. It is a lightweight flexible material with good thermal insulation properties. Nevertheless, you should be careful, when recycling, which PVC is not suitable for - 1 bottle of PVC may degrade the recycling of 30-50 thousand PET bottles.

In the collection LOAP, you will find PVC in sleeping pads.
Rip Stop RS Rip Stop fabric was developed in the USA during WWII. It is a fabric with high strength produced by a special technique.  5-8 mm thick warp threads are woven into a thin fabric. This is why a divided structure (mostly "squared", "diamond-shaped" or "hexagonal") is typical of products with Rip Stop. The greatest advantage of Rip Stop lies in the increased resistance to tearing. In case of a rupture the damage is minimum due to "grids" from warp threads.

In the collection LOAP, you will find Rip Stop in backpacks and sleeping bags.
 Fibreglass GRP_sklolaminat Those who want to save money, use  fiberglass. And they don't have to feel ashamed about it, as it is about the most common material used for rods in tents. The lower price is reflected in the relatively higher weight of rods. Also they frequently tend to break at the edge of the metal couplings, when you set up and disassemble the tents too often. You need to handle them carefully and avoid doing "wild" things in the tent;-)

In this collection, you will find LOAP fiberglass in tents.
Thermoplastic rubber TPR_1 TPR stands for thermoplastic rubber, a kind of high quality synthetic rubber. It is often confused with TPE, which is plastic however. Unlike TPE, glues stick well to TPR and thus it is more suitable for manufacturing of shoe soles. The advantages of TPR include heat resistance and low pressure deformation, in other words, the shoes are worn out less

In the collection LOAP, you will find TPR soles in most shoes.
Viscose Viskoza_1 Viscose is a synthetic fiber, but - surprise, surprise - it is made from natural cellulose, i.e. wood. Products made of viscose fibers are pleasant to the touch, they absorb humidity well and they do not crease. The popularity of the shiny viscose stems from its properties similar to natural silk. Yarn is most often used to manufacture outerwear and linings.

In the collection LOAP, you will find viscose in some ladies summer shirts or tank tops.
