About This Product

Whether we're running rim-to-rim or just getting in some misty morning miles, the Mountain Equipment Katam Jacket is part of our kit. The highly breathable membrane shuts out the clouds' torrent without making sweat rain underneath, and the adjustable hood, cuffs, and hem stop gusts from blowing droplets inside. When the skies clear, the ultralight build packs away small inside our hydration vest.

Why It Lasts

Three-layer Gore-Tex construction bonds the waterproof membrane directly to both the face fabric and the liner, creating a single laminate that won't delaminate the way 2-layer jackets eventually do. The face fabric is a high-denier nylon that resists abrasion from pack straps and rock contact. Fully taped seams, water-resistant YKK zippers, and a helmet-compatible hood designed for actual mountaineering, not fashion hiking. Mountain Equipment was founded by climbers in the UK and tests their gear on Himalayan expeditions.

Known Weaknesses

Gore-Tex's DWR (durable water repellent) coating degrades after 1-2 years of use and needs to be reapplied with Nikwax or similar treatments — without it, the face fabric wets out and the jacket feels clammy even though it's still waterproof. Not breathable enough for high-output activities in moderate temperatures. Heavy for a shell jacket compared to ultra-light options from Arc'teryx. The styling is decidedly mountaineering, not urban.

Darn Tough Men's Hojo Over-the-Calf Cushion Socks

Knit in Northfield, Vermont on 168-needle machines that create a denser weave than standard socks. The merino wool blend (typically 61-66% merino) is naturally antimicrobial and moisture-wicking, with nylon reinforcement at the heel and toe where socks actually wear through. The unconditional lifetime warranty is the real deal — if they develop a hole for any reason, you send them back and get a new pair. BIFL community consensus puts these as the single most-recommended clothing item on the subreddit.

Barbour Men's Ashby Wax Jacket

The waxed cotton outer shell (6oz or 8oz Sylkoil) is a time-tested weatherproofing method — the wax fills the weave and makes the fabric wind and water resistant without any membrane that can delaminate. Barbour's re-waxing service (or DIY with Thornproof Dressing) restores the waterproofing indefinitely. The corduroy collar, brass hardware, and ring-pull zippers are chosen for longevity over fashion. Made in South Shields, England since 1894. The Beaufort and Bedale models are favorites of farmers, gamekeepers, and the British countryside crowd who actually need their jackets to work.
