The ultimate for cold cragging days or for climbers who suffer from cold hands
Building on the responsive freeride performance of our best-selling Boundary skis, our Boundary Pro Series features powerful, hard-charging models designed with the help of our pro athlete team.


Sure, we’ve all been there.

You’re lured in by sending temps then BAM! You’re hanging on the end of the rope due to a case of numb fingers. Well, at Black Diamond, we set out to once and for all crush the problem of numb fingers, and now we’re proud to introduce the Hot Forge Heated Chalk Bag.

Built for climbers who suffer from cold hands, or those who are in constant pursuit of high friction but still battle with numb tips, the Hot Forge Heated Chalk Bag combines our innovative 3-level heating system utilized in our ground-breaking Solano gloves, with the technology of our Hot Forge insulating jacket, to give you the ultimate sending machine.


Our ultra-thin, well balanced USB-rechargeable headlamp that also runs on standard AAA batteries, the Sprinter 275 is purpose-built for longer distance pre-dawn/post sunset runs that require the reassurance of longer battery life.

The light's updated optical efficiency provides a balanced beam with brighter light and you can easily track battery life with a six-setting, three-LED batter meter.

The Brightness Memory feature allows you to turn the light on and off at the chosen brightness without reverting back to a default setting and the PowerTap Technology makes for instant brightness adjustment settings.

The light's perforated elastic headband is designed for improved breathability while running, excellent front/back balance and a red taillight strobe in the rear adds visibility in urban areas but can be turned off when you're on the trail.

Now running our new modular BD 1800 rechargeable battery, the Sprinter 275 is modular, accepting either the rechargeable battery or standard AAA alkalines.

In addition, the storm proof design keeps the Sprinter 275 going in any weather with regulation for constant illumination through the life of the battery

By combining 80 gram insulation with our Hot Forge design, we landed on a bag that not only houses the heating element, but also traps heat effectively. What we created is a revolutionary heated chalk bag with three different temperature settings depending on the level of numbing out you typically experience given the ambient climbing conditions.

"With the help of BD and their team of top-notch engineers and designers, I now have the ultimate secret weapon for sending."
