In preparation for its UK launch, Tierra started working with the International School of Mountaineering (ISM) earlier this year, becoming the 'Official Clothing Partner of the ISM'.
Adrian Nelhams describes his first impressions of the jacket...
Test Conditions: I’ve worn the Tierra Roc Blanc Jacket for 10 weeks this winter icefall climbing in both the European Alps & the Canadian Rockies – over 50 days climbing ice & mixed routes.
Fabric: The Roc Blanc uses the new generation, three-layer Gore-Tex Pro that features a brand new multi-layer membrane, a more durable micro-grid backer fabric and 70 denier top face fabric. Gore-Tex Pro is best for extended trips in severe conditions. The new Pro is designed to be more breathable than its predecessor with increased ruggedness, a solid no-nonsense material that is great for comfort on extended trips and can stand up to the increased abrasion from heavier packs, which makes it far better suited for longer trips into the higher mountains in both summer & winter where you’ll encounter the worst of what the weather can throw at you.
Fit: The Roc Blanc’s a very good tailored fit, feeling very trim with no excess, but being well articulated at the same time. When placing the ice tools above your head the jacket doesn’t ride up above your harness. The sleeves are a good, long length, again well cut, so that when you need to stretch out, the cuffs stay where they should and don’t ride up your arm.
Features: The jacket is well designed and very functional. The lines are clean with minimal excess due to the athletic fit. Two crossover chest pockets provide quick and easy access. They are a good size to fit a map, spare gloves or a knife and abseil tat. Unlike most jackets, the Roc Blanc has unique and conveniently placed ventilation zips that sit just in-front of the arm rather than underneath the arm (where they can be awkward to open and close).These zips allow easy access when on the move and ventilation is a priority without the hassle of stopping or having to use two hands. The sleeves are well-articulated, they’re a trim fit with no bulky excess and good strong Velcro fasteners which really wrap around and seal the cuff. The storm hood is a good size allowing the helmet to fit neatly underneath it. Single-handed hood adjusters tie back neatly into the inside of the jacket, so they don’t flap back and hit you in the face. The wired peak keeps off the worst of the weather and gives it a great shape thanks to the combination of a sheet adhesive and wired thread. The zips throughout are water repellent YKK zips with a 2 way opening for harness compatibility and ventilation. They are neat & don’t feel like they’re going to fail any time soon!
It’s a solid no-nonsense jacket which looks great, is well designed, functional, feels comfortable and a lovely trim fit.
