Armstrong 5 Panel Bump Cap

The Armstrong 5 Panel Bump Cap is a lightweight protective cap built for foiling, wing foiling, and surfing. Made by Armstrong Foils, it sits between a standard water cap and a full helmet, using an internal ABS bump shell to deliver light impact protection in a low-profile package. Armstrong positions it as a practical compromise — adding meaningful head coverage without the weight and bulk of a traditional helmet. The cap is constructed from 100% polyester with quick-drying properties, and it ships in two colorways: Black and Signal Pink, the latter part of Armstrong's Signal Series focused on on-water visibility.

• Shell: Internal ABS bump shell
• Fabric: 100% polyester, quick-drying
• Brim: Short brim (optimized for visibility)
• Ear protection: Integrated ear covers
• Fit system: Adjustable chin strap and back strap
• Logos: Reflective
• Available sizes: S/M (58 cm) and L/XL (62 cm)
• Colors: Signal Pink, Black

This cap targets foilers and surfers who want some head protection but don't want to wear a full helmet. It's well-suited to riders who are comfortable on the water and looking to reduce risk from incidental contact with their board, mast, or wing rather than seeking certified impact protection. Armstrong is clear that the Bump Cap is not a replacement for a traditional helmet, so riders in high-consequence conditions or those still learning should consider dedicated helmets instead.

The integrated ear covers add protection against eardrum injuries from high-speed water impact — a real concern in foiling where wipeout speeds can be significant. The adjustable chin and back straps keep the cap secure during falls, while the short brim maintains sightlines during maneuvers. At 39.99 USD, it's an accessible option for riders who might otherwise skip head protection entirely because of helmet discomfort.

Within Armstrong's own headwear range, the 5 Panel Bump Cap sits between the 5 Panel Water Cap ($29.99), which is a standard breathable water cap with no impact protection, and the Bucket Bump Hat ($49.99), which uses a similar ABS shell concept in a wider-brimmed bucket hat silhouette. Riders who prefer more sun coverage around the ears and neck may lean toward the Bucket Bump Hat, while those who want a streamlined five-panel fit will find this cap more appealing.

In the broader market, bump caps occupy a niche that traditional helmet brands like Sandbox or WRSI don't specifically address — they're lighter and less obtrusive, but they don't carry formal impact certifications. The Armstrong 5 Panel Bump Cap competes most directly with soft-shell surf helmets and impact caps from brands like Simba and Shred Ready, though each takes a slightly different approach to balancing protection and comfort.
