Technology of the Bulgarian backpacking rucksacks Tashev



Air Mesh
This breathable fabric is designed for areas that are in direct contact with the body - shoulders, back, lumbar belt. Special 3D fabric provides air flow and ventilation, allowing the skin to breathe and reducing perspiration. It consists of 3 layers - top layer grid connected to the basic layer by millions of polyamide fibers, forming a kind of spider-web in the middle, through which air passes freely when the backpack is on. Removes sense of "bonding" with the backpack and dramatically increases comfort. Advantages of breathable backs are mostly appreciated during long trekking in hot weather.


CORDURA® fabric is what many of the most respected brands, retailers and militaries around the world use when they need to make a product that’s durable, versatile and reliable. Constructed using high tenacity fiber technologies, weight for weight, CORDURA® fabrics are exceptionally durable. Fact is, no matter the application, our fabrics are “best-in-class.” But more importantly, they have to pass our own stringent test criteria before they can earn the CORDURA® brand name. They’re available in a wide range of weights – from ultra lightweight to heavy weight. And CORDURA® fabrics come in many different constructions and textures. All in all, they’re the fabrics that make strong, long-lasting products even tougher in several categories - from outdoor gear and workwear to luggage, military and upholstery.

Tashev import Cordura® from a DuPont®-licensed factory in Germany. The fabric has lightweight silicon impregnation and Teflon® coating - protection that further strengthens tha fabric and makes it easy for maintenance.

Worldwide brands usually use Cordura® for the backpack's heavy-loaded zones - bottom, back. Tashev backpacks are ENTIRELY made of Cordura® fabric.

Technologies of hiking and hunting shoes Alpina

SympaTex® fabrics are branded waterproof and "breatheable" fabrics (leather or textile) made or licenced by SympaTex® Technologies GmbH. They all feature a waterproof, windproof and breatheable membrane, laminated to fabrics (leather or textile) either on its inner surface or sandwiched between two fabric layers (often marketed as "3 layer laminate"). The latter system offers greater durability, by better protecting the integrity of the SympaTex® layer from abrasion to both the outside and the inside of the garment or footwear. The SympaTex® membrane like Gore-Tex® does not allow water to get in from the outside, but water vapour molecules are transported through the membrane from the inside to the outside by way of an absorption & evaporation process. This moisture transfer through the membrane is what is referred to as "breatheability".


The Alpitex membrane has been developed by Alpina engineers on the basis of long experience and constant user feedback. The membrane is water-resistant and allows for good boot ventilation as well as comfort for the foot.

Compared to standart  boot linings,the Thinsulate insulation system guarantees conditions for the feet that are twice as warm as other boots.The feet can breathe and regulate the natural physical feeling of the foot.Consequently they stay warm even in unusually wet weather conditions.
Nearly twice as warm as any other insulation, including down, Thinsulate is breathable and washable. It absorbs less than 1% of its weight in water and stays warm in damp conditions.
The respected Vibram sole brand guarantees a steady step on all types of surfaces. Its firmness, supplemented by the appropriate back and front pieces, makes the sole suitable for use with automatic crampons.
Sole, developed by Alpina - produced in the factory, which manufactures Vibram, with the same qualities, providing better traction and stability.
Outsole of natural rubber, which ensures durability, excellent support and traction on rough terrain.
Outsole of natural rubber that is treated as other thermoplastic materials; a polymer -elastomeric material which has flexibility and softness. It is known as ethylene vinyl acetate and a copolymer of ethylene and vinyl acetate.
EVA soles are the lightest of all solid soles. They are fastened to the top part with a special adhesive technology at very high temperature.
Technology which injects sole directly to the shoe. This provides greater strength, water resistance, softness, durability and comfort. Lightness, flexibility and high durability thanks to the technology by which the shoes and soles are connected without glue or stitching. Light and robust sole.
Innovative sole Multifunction®, providing good grip and a 25% increased stability on slippery terrain, snow and ice. The technology of production of the sole Multifunction® is based on a completely new method intended mainly for shoes that will be used in harsh winter conditions. By injection and implement of textile elements into the sole, it caused the effect of "embedded crampons", which enhances traction on slippery surfaces and ensures increased durability and stability.
Anatomical shape of the insole of the shoe.
Expanded PU midsole for soft and comfortable walking.
Thermoplastic material in the heel area for placement of semi crampons.
Extra padding for absorbing vibrations in the sole.
Offers long-lasting comfort, combining great shock absorption with flexible freedom of movement.
Rubber reinforcement in the front of the boot protects the  foot sharp stones and unstable terrain.
Rubber provides the boot and the toe with effective protection from external elements,impacts, and rocks.
VCP - Volume control plate
The volume control plate, positioned under the insole, allows for precise adaptation of the volume independently for the left and right foot. If the plate is removed the shoe has greater volume.
In order to take the weight off the back part of the ankle,which carries most of the load during long treks up steep inclines,many ALPINA  boots comewith a "flex zone"at the back. This alleviates pressure  on the Achilles'  tendon, which enables easier  and more relaxed uphill walking.
Quick and effective lacing,ensuring the most secure fit for the foot, is made possibly by an original solution that uses a ball-bearing device.Your step will be lighter and more precise.
Natural materials,  special soles that cushion the step and airy membranes insure a comfortable feeling throughout the day- at work as well in your free time.
Today's trend is to use  natural materials  that  feel  good  against the skin,and this is just what Alpina does.Natural materials  let our boots breathe like our own skin,which makes wearing them all the more comfortable and enjoyable.
For most of its footwear lines Alpina offers a wide spectrum of women’s models in colors designed to please a woman’s taste. Specially designed boot collars in our women’s models are adapted for the more sensitive, lower, and more pronounced calves of women. Alpina’s women’s boots are made on the basis of a women’s last, which is narrower and lower in the front and shaped to match the anatomy of the female foot.
Alpina`s junior`s boots are made on the basis of a junior`s last, which is provided for free growth and natural evolution of junior`s feet. 
Alpina kids shoes models are made on the basis of the child's foot, which is constantly growing and shoes must meet the natural evolution of the child's foot.
