What Our Gearhead(R) Experts Are Saying:"This shell was my go-to for a winter route in the Tetons-GORE-TEX PRO blocked out the spindrift and gusts, while the articulated sleeves let me swing tools overhead without the hem lifting. It packs down surprisingly well and nails the balance of durability and comfort."When our route points toward frozen couloirs and mixed terrain, we rely on the Latok Alpine GTX Jacket to push higher into the storm. Rab engineered this alpine climbing shell for cold, vertical missions, balancing reliable weather protection with the mobility and comfort needed for steep, exposed movement. Built with GORE-TEX PRO fabric and dialed mountain-specific features, this is the shell we count on when the forecast reads high winds and full commitment. The 3-layer GORE-TEX PRO construction with an ePE membrane stands up to snow, ice, and sharp gear while offering breathability during full-day pushes. Sleeve articulation ensures unrestricted reach for swinging ice tools or reaching gear, and the TriPoint hood fits seamlessly over a helmet. Details like a RECCO(R) reflector, fleece-lined chin guard, mitt-friendly adjustments, and storm-sealed zippers show Rab's alpine pedigree in every stitch. It's light enough for the pack and tough enough for the climb.
