JOURNAL OF ALPINE INTEGRITY, TECHNICAL SPECIFICATIONS & HIGH-ANGLE DISCIPLINE
Nine in-stock Suunto GPS watches compared — battery life, weight, offline maps, dual-band GPS, and price — with sourced picks for backcountry skiing, mountaineering, everyday adventure, and diving.
Snowshoe size charts for Tubbs, MSR, and Atlas side by side: weight-to-length sizing for Tubbs Tubular and Flex, MSR Evo Trail/Ascent load ratings, and Atlas weight ranges. From a fit, sizing & standards specialist.
A wide snowboard starts at a 260mm waist width. Match your boot size to the minimum recommended waist width with charts from Jones, evo, and Tactics, plus the signs your board is too narrow. From a fit & sizing standards editor.
Last-season snowboards drop 30–80% off from March to June and again over Labor Day. Previous-season boards are never restocked, so end sizes and popular models sell out first. A buying strategy from an equipment selection & geometry editor.
A buyer's checklist for inspecting used skis before purchase: topsheet, edges, base, bindings, brakes, and DIN. What to look for, green flags, and red flags at each step.
A shop buyer's guide to ski waist width: what the waist number means, a width-band by terrain table, the trade-offs of narrow vs wide, and a decision framework for choosing by where you ski most. From a former ski-shop equipment buyer.
Free alpine ski length calculator (ski selector). Enter height, weight, ability, and terrain to get recommended ski length, waist width, and turn radius — from a former ski-shop equipment buyer.
Chassis geometry, boot last widths, DIN mechanics, and binding elasticity.

Coming Soon →Surface deck flotation, articulated heel bars, and powder traction rails.
Open Dossier →Mountain paddle track pitch, sled haul rigs, and backcountry logistics.
Coming Soon →Ram-air foil physics, depower bar triggers, and glacier plateau winds.
Coming Soon →Monochrome field plates captured across glaciated arêtes, wind-scoured ridgelines, and deep-accumulation couloirs.
Aiguille du Midi knife-edge exit onto the Vallée Blanche. Rime ice accumulation and 40-knot westerly wind scour create hard-packed sastrugi requiring dual-point crampon penetration.
Deep northern maritime powder basin. Wide tip rockers (112mm underfoot) provide flotation above submerged crevasse bridges.
Assessing steep 48-degree couloir snowpack integrity with extended column test (ECTP21) prior to descent commitment.
NNN, SNS, Turnamic, and ProLink cross-country bindings compared: which boots fit which bindings, brand-to-system map, and how to identify your boot sole.
A buyer's case for fitting boots before choosing skis: how boot fit drives comfort, control, and injury prevention more than ski selection, when ski choice does matter, and a what-fit-gets-you vs what-skis-get-you comparison.
Accurate ski boot mondo (mondopoint) sizing chart: convert US men's and women's shoe sizes to mondo, EU, and UK, plus comfort vs performance fit and how to measure your foot. From a former ski-shop equipment buyer.
Ski boot last width and foot volume explained by a former ski-shop buyer: how to measure your foot, the 95–106mm last bands, which brands fit narrow/medium/wide feet, and the 2mm-per-size rule.
Ski boot sole types explained: ISO 5355 Alpine, GripWalk (ISO 23223), and ISO 9523 Touring soles, plus a sole-type by binding compatibility matrix so you know what fits what before you buy.
Boot sole length (BSL) is the millimeter measurement that drives ski binding setup and forward pressure. Learn how BSL differs from mondo size, the sole standards (ISO 5355, GripWalk, ISO 9523, WTR), and why a certified tech sets forward pressure and DIN.
Ski boot flex index (the number like 90, 110, 130) explained: what it means, a flex-by-ability table, and how body weight and brand scale the number. From a former ski-shop equipment buyer.
Free ski boot fit calculator. Enter your size, foot width, instep, weight, ability, and terrain to get mondo size, last width, volume class, flex index, and brand fit recommendations — from a former ski-shop equipment buyer.
A buyer's guide to how each major ski boot brand tends to fit — last width, volume, instep, and calf — with a brand-by-brand fit table and per-brand notes. From a former ski-shop equipment buyer.
How to buy skis and bindings separately: match brake width to ski waist (equal to 15mm wider, 5–10mm ideal), read tip/waist/tail dimensions, choose a mount point, and decide between a flat ski and a system package. From a field setup & maintenance tech.
Educational ski binding DIN (release value) estimator based on the ISO 11088 weight method: enter weight, height, boot sole length, skier type, and age for an indicative DIN. A certified technician must set and test the final value.
Nylon vs mohair vs blend climbing skins compared on grip, glide, weight, durability, and water behavior — with a tour-length recommendation so you pick the right skin plush for short steep climbs, long days, or all-around touring.
