Question 1

Can I wear impact shorts under my regular ski pants, or do I need special pants?

Accepted Answer

Most impact shorts are designed to be worn under your regular ski pants as a base or mid layer. You don't need special pants, but you do need pants with enough room to accommodate the padding comfortably. Slim-fitting or tight ski pants may not have enough space, creating pressure points and restricting movement. Try the combination at home before your trip. If your current ski pants are too tight, either size up in pants or choose ultra-low-profile impact shorts with thin smart foam pads.

Question 2

Do I really need CE Level 2 protection, or is Level 1 enough?

Accepted Answer

CE Level 1 (≤18 kN force transmission) is sufficient for most recreational skiers with normal bone density. CE Level 2 (≤9 kN) is strongly recommended if you have osteoporosis, low bone density, a previous hip fracture, or if you ski at high speeds, in the terrain park, or race. Since hip fractures can occur at 3-10 kN depending on bone density, Level 2 provides a much larger safety margin for those at elevated risk. For healthy younger skiers, Level 1 with smart foam is a practical balance of protection and wearability.

Question 3

Will impact shorts make me too hot while skiing?

Accepted Answer

They add warmth, but modern designs manage this well. Smart foam pads are thinner and less insulating than thick EVA foam. Many models include mesh panels in non-padded zones for ventilation. If you run hot or ski in spring conditions, choose a high-breathability model with extensive mesh construction. You can also wear a thinner base layer underneath to help wick moisture. On cold days, the extra warmth is actually welcome. The key is matching the breathability rating to your typical skiing conditions and personal temperature preferences.

Question 4

How do I know if the pads are positioned correctly over my hip joints?

Accepted Answer

The hip joint you need to protect is the greater trochanter—the bony prominence on the outside of your upper thigh, roughly at the level of your crotch. Put the shorts on and feel for this bone through the pad. The center of the pad should sit directly over this point. If the pads are too close together (common for women in unisex shorts) or ride up above the hip joint, they won't protect you in a fall. Walk around, squat, and mimic a skiing stance—if the pads stay over the bone through movement, the fit is correct.

Question 5

How long do impact shorts last before needing replacement?

Accepted Answer

Smart foam pads (D3O, SAS-TEC) typically maintain protective performance for 3+ seasons of regular use. EVA foam pads may compress and lose effectiveness after 1-2 seasons. The compression short fabric usually lasts 2-4 seasons depending on washing frequency. Inspect pads at the start of each season—if they feel permanently compressed, cracked, or have lost flexibility, replace them immediately. Also replace after any major impact event, as smart foams are designed for optimal performance in a limited number of significant impacts.

Question 6

Are impact shorts the same as snowboard butt pads?

Accepted Answer

They're similar but not identical. Both are padded shorts for winter sports, but the emphasis differs. Snowboard-specific crash pants typically prioritize tailbone and buttock padding because snowboarders fall backward more often. Ski-specific impact shorts emphasize hip joint protection because skiers fall sideways onto the hip more frequently. Many modern impact shorts cover both zones well and work for either sport. If you ski and snowboard, look for a model with comprehensive coverage including both hip joints and tailbone.
