The G1 Expe is the result of an ongoing dedication to make the finest high altitude boots in the world. Boreal understands that at the rarefied extremes of high altitude mountaineering the right equipment can make all the difference and this is why G1 Expe has been carefully designed, field tested and refined to guarantee exceptional levels of performance and reliability, without compromise.
Bridging the gap between our G1 Lite and G1 Expe models, Siula is perhaps the most versatile high altitude boot available. Warm enough for the coldest alpine conditions and tough enough for multi season use, Siula is the ideal choice for alps in winter and 7000m summit bids.
We have further enhanced our most popular double boot, taking comfort and performance to another level. Careful selection of the best modern materials has enabled us to reduce weight without compromising warmth. G1 Lite is truly a modern classic for winter alpine ascents and 6000m peaks.
