Waterproof Frame Bag

It depends on your frame size and needs. Measure your main triangle: from seat tube to head tube along the top tube, and from bottom bracket to this midpoint. The 2.5L fits smaller frames or minimal setups, the 4L works for most medium frames and day trips, and the 5L maximizes space on larger frames for multi-day tours. Check the product dimensions against your frame measurements.

Frame bags work best on hardtail bikes with sufficient clearance between the top tube and rear shock. Measure your available triangle space carefully and consider if you want to keep water bottles or not. ARKEL frame bags are flexibles to adjusts to different shapes and contours. Some full-suspension designs have limited room, so you may need the small 2.5L or medium 4L size or might want to consider adding fork bags for more carriage capacity.

Arkel offers two frame bag options: a water-resistant model for typical conditions and this 100% waterproof model for maximum protection. This waterproof version features sealed seams and fully waterproof fabric construction, proven through multi-day bikepacking trips in heavy rain to keep gear completely dry. Choose this model if you ride year-round, tour in unpredictable climates, or need absolute confidence that your critical gear stays dry.
