Impact protection for riders
Snowboard impact shorts are padded briefs or three-quarter shorts you wear under your boardshorts or bibs that wrap the tailbone, hips and upper thighs in closed-cell foam or gel inserts, so a fall onto packed snow or hard ice stops at the padding instead of the bone. They come in 2 main coverage styles: brief-style for warm conditions and three-quarter for cold. A standard pair holds 4 to 6 impact zones, each rated to absorb a landing at speeds up to 40 km/h before the force reaches the pelvis. Together with knee pads and a safety leash, impact shorts close the protection loop for a rider who spends a full season in the park or on steep terrain.
Protective gear is the fastest-growing shelf on the catalog. Riders who already Snowboard gear from board to boots in a single order often add the impact set at the last minute, and the product pages here group the 3 core items so you can compare padding density, weight and price in one pass. The same catalog also carries outerwear and boots: Pick a snowboard jacket to match the insulation you need, then Choose snowboard boots to lock the stance before you head out. Every category on this site follows one rule: Ski, snowboard and watersports kit, bought end to end, with the seasonal cycle from pre-season fitting through post-season kit care covered in the guides that sit next to each product.
Impact shorts: what sits under the pad
Impact shorts carry the load through 3 layers working in sequence. The outer shell is a 4-way stretch nylon or polyester blend, usually 210 to 300 denier, that slides over snow without catching. The middle layer is the impact medium itself: closed-cell EVA foam at 15 to 20 mm thickness for daily riding, or a gel-filled pocket for park riders who land harder and more often. The inner liner is a flat-lock mesh that wicks sweat and keeps the pad seated when you twist through a turn. Fit matters as much as material; a pair that rides at the natural waistline and sits 10 to 15 cm above the knee covers the coccyx, greater trochanter and lateral thigh in 1 continuous panel. Sizes run from XS to 2XL, and the 4 most common sizing mistakes come from measuring over a base layer, ignoring the drawcord range, choosing a brief style in temperatures below 5 degrees Celsius, and skipping the try-on after a 30 minute session because the pad compresses under body heat.
Coverage styles and when each fits
Coverage style splits into 2 categories that map directly to temperature and terrain. Brief-style shorts cover the seat and upper thighs only, leaving the hips exposed to air so they suit 8 degrees Celsius and above; they weigh between 180 and 250 g and pack to the size of a fist. Three-quarter shorts extend the panels to mid-thigh, add hip wings, and run 280 to 400 g, which makes them the standard choice for 0 to 8 degrees. A 3rd option, the full-impact bib, exists for halfpipe and big-mountain riders who need hip and back coverage in one garment, but it overlaps with a separate impact jacket and costs roughly 2x the price of a three-quarter pair. For a rider who splits time between groomed runs and the park, the three-quarter style at 20 mm foam is the 1 piece that covers the most ground for the least bulk.
Knee pads: the second stop before the bone
Knee pads protect the joint from the two failure modes that a snowboard rider meets most: a direct blow to the patella during a forward fall, and a lateral twist when the board catches an edge. A typical pad holds a 1 hard cap, 2 foam layers and a strap or sock system, and the 4 main mounting styles are as follows.
- Strap-on pads: 3 velcro straps (upper calf, mid-shin, lower calf) hold the pad in place; they fit over any boot or pant and weigh 120 to 180 g per knee.
- Sock-style pads: a neoprene or spandex sleeve with an internal hard shell pulls on like a tight sock; they add 20 to 30 g over a strap pad and stay seated through 2 or more hours of riding without readjustment.
- Built-in pad pants: the pad is sewn into the knee of a snowboard-specific pant; this is the cleanest look but locks you into a single pant size, and the pad cannot be swapped when the foam compresses after roughly 80 to 100 hours of riding.
- Hybrid sleeve-plus-strap: a sock shell with 1 additional velcro strap across the shin; it adds 15 g over a pure sock pad and is the most common choice for park riders who land on one knee repeatedly.
The cap material splits between ABS plastic, which is rigid and lighter at 30 to 45 g per cap, and TPU, which flexes under low-speed contact and absorbs more energy at higher speeds but adds 5 to 10 g. For a rider under 70 kg, an ABS cap with 15 mm EVA behind it is sufficient; above 80 kg, the TPU cap with 20 mm foam keeps the force under the threshold where cartilage damage becomes likely. Both options sit in the 25 to 40 pound price band per pair, which is 10 to 20 percent of the cost of a mid-range board.
Safety leash: the link between rider and board
A snowboard safety leash is a 2.7 m to 3.0 m cord, usually 6 mm diameter nylon or polyester, with a quick-release buckle on one end that clips to your jacket or boot and a 360-degree swivel loop on the other end that threads through a board binding. The leash does 3 things at once: it keeps the board within 2 m of your body so a slipped binding does not send the board carving across a run into another rider, it acts as a visual marker in whiteout or low-light conditions, and it gives a fallen rider 1 handle to reposition the board without unclipping. The 2 standard attachment points are the jacket hem D-ring and the boot cuff loop; the hem clip is preferred because a boot clip adds 5 cm of effective length and lets the board swing wider in a hard fall. A 6 mm cord rated for 150 kg of static load is the minimum specification, and the quick-release buckle should hold 25 kg of pull force before it opens, which is well above the force a 70 kg rider generates in a fall.
Choosing the set: sizing, weight and the 3-item budget
Choosing the set means matching 3 items to your body, your terrain and your budget in one pass so the layers work together instead of fighting. The sizing chart below covers the 3 products against a 175 cm, 75 kg rider as the reference point.
| Item | Reference size | Weight | Key spec to check | Typical price band |
|---|---|---|---|---|
| Impact shorts (3/4, 20 mm foam) | M (waist 84 to 94 cm) | 320 g | 4 or 6 impact zones; hip wings included | 45 to 90 pounds |
| Knee pads (hybrid sleeve-plus-strap) | One size, fits 70 to 100 kg | 150 g per knee | TPU cap, 20 mm EVA, 1 extra strap | 30 to 55 pounds per pair |
| Safety leash (6 mm, quick-release) | 2.7 m to 3.0 m, one size | 60 g | 150 kg static load rating, 25 kg release force | 8 to 18 pounds |
A 3-item set at the mid-range of each column lands between 120 and 150 pounds, which is 15 to 20 percent of the cost of a complete board setup. The sizing rule that prevents the most returns: measure impact shorts at the natural waistline with the drawcord at the 30 cm mark, and size knee pads by boot volume rather than shoe size, since a 32 or 33 boot needs a different shell depth than a 27. The leash has no sizing beyond length, but a rider over 185 cm should take the 3.0 m option so the cord does not snap taut in a hard fall and transfer the full load to the jacket seam.
Seasonal care: from first session to end-of-season storage
Seasonal care for the 3 items follows the same rhythm as the rest of the board: inspect before the first session, clean after every 4 to 5 runs, and store flat with the padding uncompressed. Impact shorts rinse in cold water with a mild detergent; the closed-cell foam does not hold water, but the outer nylon does, and a 10 minute soak removes the wax and grit that scratch the shell. Knee pads wipe the cap with a damp cloth and check the straps for delamination at the velcro edge, which appears after roughly 100 hours of use; a pair of TPU-cap pads at 20 mm foam retains 85 to 90 percent of its original absorption after a full 6 month season if you avoid leaving them in a hot car. The leash needs the least attention: rinse the cord after each session, check the quick-release buckle for sand or ice chips, and inspect the 360-degree swivel for play; a swivel that moves more than 5 mm of lateral play is past its service life and should be replaced before the next season. Storing the full set in a mesh bag on an open shelf, away from direct sunlight, keeps the foam from off-gassing and the nylon from UV brittleness through the 6 month off-season.
