Features
For those seeking an added level of safety without the weight and volume of an airbag pack. The SB 40L, featuring the Safeback avalanche survival system, is one of the lightest avalanche safety packs on the market after the SB 30L, while also being fully featured and able to accommodate hut trips and overnight objectives. The SBX system can be easily removed and only takes up .75L in the pack vs. the 4-6L of a typical airbag pack, giving the SB 40L the ultimate versatility. Read more about Safeback below.

Safeback Tech - Air supply for 90 minutes. A lighter and smaller alternative to an airbag. The SBX system provides an active air supply for 90 minutes in the event of an avalanche without having to put anything in your mouth. It works by circulating fresh air from the surrounding snowpack, flushing out carbon dioxide that has been exhaled, and delaying asphyxia. The fresh air is pulled in with an electronic fan unit and circulated around the mouth through tubes installed in each shoulder strap. Reasons we are excited about Safeback:
- It can easily be turned off so it can be activated pre-emptively.
- Works for treewell burials.
- The SBX system can be removed and takes up only .75L in the pack vs. the 4-6L of a typical airbag pack.
- No mouthpiece required.
- Significantly lighter than airbag systems.
SBX Integration - Removable SBX System. SBX works by pulling in fresh air with an electronic fan unit which is then circulated around the mouth through tubes installed in each shoulder strap. The SBX system can be easily removed and re-installed in a few minutes giving you a super versatile pack.
Avy Tool Pocket - Quick access to your tools. Raide packs prioritize quick access to your avalanche tools, and really quick access to your probe, while also improving the space efficiency and bringing the tools closer to your center of mass. The probe can be accessed without taking your pack off for quicker rescues and more efficient snow study. The shovel can be accessed by dropping one shoulder strap. The pocket is made to accommodate shovels up to 11.5" in width and most large shovel handles. By putting the probe and shovel handle on the pack’s side panels, we maximize space efficiency and bring the weight closer to your center of mass.
Volume - 40L, expandable to 50L. Stay compact on your dawn patrol lap or go into hut trip mode with the expandable roll top.
Materials - Ultra 400TX. The LF 40L uses UHMWPE based materials (generic Dyneema) in different constructions:
- The main fabric is Challenge Ultra 400TX, which is 2x more tear-resistant and 8x more abrasion-resistant than competing ultralight fabrics.
- The cinch top is a 210d nylon with UHMWPE ripstop.
The rolltop is a 50d nylon ripstop with UHMWPE cross-ply.
Back Panel Access - Full access to main compartment. The only way to get access to all of your gear regardless of how you are carrying your skis. We think back panel access is essential to any backcountry ski pack built for moving efficiently in the mountains.
Back Panel Design - Breathable, durable, stiff. The back panel this year is updated and is one of the biggest innovations on the pack. The new back panel is lighter, more durable, more breathable, and stiffer. We made it stiffer because many backpanel-access packs bulge outwards when stuffed and lose their carrying comfort and breathability. We developed a molded composite insert with anti-bulge ribs that keeps the back panel shape unless stuffed to the max.
No zip stash - No zipper transitions. The SB 40L has two compartments that you can quickly stow gear in without touching a zipper. Both act as wet pockets with drainage to keep your wet gear, like skins, separated from your dry gear.
Stowable Roll Top - Storm more → Bluebird mode. Roll up the rolltop for a weatherproof closure and get an extra compartment. If it goes blue and you don't want to deal with the roll top use the stow clips to keep it out of the way.
Ski Carry - New modular ski/board carry. The diagonal ski carry can be moved between three positions. The first two are either diagonal direction, and the third position is for skimo carry. The pack also has A-frame and vertical snowboard carry.
Helmet Carry - Integrated helmet carry. Raide had enough of the dingy (dinky?), strap-on helmet carry systems. They have seen too many people lose them, and they aren't secure enough to put anything inside your helmet like crampons. We built our helmet carry right into the pack so it can't be lost. It is also high up enough to be out of the way of the diagonal ski carry and still allows the pack to sit flat on the front.
Ice Tool Carry - No-snag ice tool carry. The ice tool carry keeps the picks of the tools fully enclosed and secure so they don't get snagged or fall out.
Removable Frame - Frame distributes weight. An aluminum frame enables you to carry heavier loads comfortably and creates a secure anchor point for any of the ski and snowboard carries. The aluminum frame runs the perimeter of the pack and is sewn into the back panel zipper, so when the back panel is closed it matches frame shape. The frame weighs 80g and can be removed.

AI FAQs
AI generated FAQs about the SB 40L Pack
How does an avalanche airbag help me survive if I get caught?
This pack does not use a traditional inflatable airbag; instead it uses the Safeback SBX system, which provides an active air supply for up to 90 minutes during an avalanche burial. An electronic fan draws fresh air from the surrounding snowpack and routes it through shoulder-strap tubes around your mouth to flush exhaled carbon dioxide and delay asphyxia, giving you more time until rescue without the bulk of an airbag.
How do I know what size I need for my frame?
Choose size S for a 17.5–19 inch torso or size M for a 19–22 inch torso. Measuring your torso length against these ranges helps you select the pack size intended for your frame.
How much does this add to the weight I'm already carrying?
The SB 40L weighs 4.14 pounds with the SBX unit installed. Its listed weight is 2.65 pounds without the SBX unit or removable frame, giving you a lighter setup when you remove those components.
Will this airbag fit with my other avalanche safety equipment?
The SB 40L has a dedicated avalanche-tool pocket sized for shovels up to 11.5 inches wide and most large shovel handles, with a separate quick-access probe position. You can reach the probe without removing the pack and access the shovel by dropping one shoulder strap.
What if I panic or don't have time to deploy it properly?
The SBX system can be activated pre-emptively and can also be turned off. This lets you switch on the active air supply before a potential burial rather than relying on a conventional airbag deployment sequence.
Does this come ready to use, or do I need to buy parts separately?
The SB 40L includes the integrated Safeback SBX avalanche survival system. You can remove and reinstall the SBX system in a few minutes when you want to use the pack without it.
How does this compare to wearing an airbag from a different brand?
The SBX system occupies 0.75 liters in the pack, compared with the 4–6 liters cited for a typical airbag pack. It provides active air circulation for 90 minutes instead of using an inflating airbag, and the removable system supports a more versatile pack setup.
Will this work if I'm trapped under trees or rocks?
The Safeback SBX system is designed to work for treewell burials. It circulates fresh air around your mouth through tubes in the shoulder straps, using an electronic fan unit to draw air from the surrounding snowpack.
What if the avalanche happens before I have time to deploy it?
The SBX system can be activated pre-emptively before a potential avalanche burial. You can turn it off again when needed, so the active-air system is not limited to a last-second inflation trigger.
