Millet Trilogy Jorasses 4S GTX Mountaineering Boots - Size Men's 9.5
The Millet Trilogy Jorasses 4S GTX is a technical mountaineering boot designed for climbers tackling steep alpine terrain, ice climbing routes, and demanding winter conditions. Its GORE-TEX Duratherm construction provides waterproof protection and insulation for cold environments, while the integrated gaiter helps keep snow and moisture from entering around the ankle. These boots are a great choice for experienced mountaineers who need warmth, protection, and support during technical climbs.
The Trilogy Jorasses combines a dual BOA Fit System with a supportive construction that makes adjusting the fit quick and easy, even with gloves on. Its Vibram outsole provides traction when traveling over rocky or uneven terrain, while the rigid, crampon-compatible design makes it suitable for technical ice climbing. With its built-in gaiter and insulated construction, this boot is well suited for everything from winter alpine approaches to climbing frozen waterfalls.
