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
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.
Duraflex
Buckles and plastic parts DURAFLEX® - made of ACETAL, which changes its structure only at -50°C, which makes them highly tolerant to high loads and low temperatures. Brand DURAFLEX® is a world leader in technology for plastic bag-parts for decades. Established in the USA, it now works worldwide, seeking to offer local production in several countries worldwide. TASHEV provides DURAFLEX® details from an Italian factory with traditions, which guarantees high quality of plastic parts in backpacks.
YKK
Japanese zippers brand YKK® is undoubtedly the best in the world. The spiral is resistant to wind-driven tension and continuous use in different conditions - very low and very high temperatures, moisture, dust, dirty environments, etc. The life of zippers depends not only on the load, but the intensity of use, i.e. the number of openings and closings. In this respect, YKK offers over 10 times longer lifespan than any other zipper. Look for the YKK logo on the slider.
Vario Back System
VBS system - adjustable support system for large volume (55-100 liters) backpacks, designed for long wearing of heavy luggage on difficult terrain. Provides maximum level of stability and comfort through precise positioning of the backpack on your back. This is done by sliding the carrier block of aluminum construction and relaxation / tightening of the regulators. Thus, comfort is guaranteed for both very low and very high people. Each bagpack comes with a detailed instruction for adjustment.
Air Ventilation
AV system /Air Ventilation/ - bearing system with static control. Applied in medium sized bags (40-45 liters), intended for lighter and / or shorter hikes up to 15 kg. luggage. AV unconstrained bearing system allows air to circulate through the vertical vent along the back. So the free breathing of the body reduces perspiration and increases comfort. Each bagpack comes with a detailed instruction for adjustment.
Integrated rain cover.
ACETATE
PC polycarbonate
The glasses are entirely made of carbon fibre (polycarbonate). Lenses made of polycarbonate are not only light, but also very tough and resistant to scratches. Thanks to the multilayer character of such lenses their thickness is ideally even, which eliminates all deformations and vision disorders.
This material makes the frames of the sunglasses light and resistant to mechanical damages.
TR-90 - Grilamid
TPU thermoplastic polyurethane
POLARIZED PROTEC G-LENS
POLARIZED PROTEC G-LENSES which are used in GOGGLE sunglasses have two different thicknesses: 0.75 mm and 1.0 mm. The polarizing effect reduces irritating glare and light flashes while increasing safety in common situations when the use of sunglasses is required. Sight comfort is guaranteed by intensifying colour recognition and sight sharpness. Most of GOGGLE sunglasses are provided with polarized lenses with 1.0 mm thickness.
OPTICAL RIM G-System
Optical rim allows corrective glasses to be fixed according to the individual needs of the customer. It is provided with all the models marked with the letter "R", e.g. T510R.
FOG BLOCK G-lenses
DUPLEX G-LENS
AIR JECT VENTILATION
Styles H830, H840, H850 and H855 ski goggles with DUPLEX G-LENS have additionally extra ventilation system which allows air to circulate between two layers of double lenses. AIR JECT VENTILATION system is the highest developed technology protecting the lenses against misting over. This system is specially designed to improve the quality of sight in the extreme weather conditions.
LENS CHANGE G-SYSTEM
This system provides the user with the possibility of changing lenses easily with the variety of lenses to adapt glasses to actual weather conditions. Goggle sunglasses equipped with LENS CHANGE G-SYSTEM include at least one additional pare of lenses.
SUPER DARK 4 G-Lens

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".

ALPITEX
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.



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.




Offers long-lasting comfort, combining great shock absorption with flexible freedom of movement.
