Gramino SagiFlow Ultralight Bidet

The Gramino SagiFlow is a minimalist bottle-cap attachment that turns any compatible bottle into an improvised trail bidet. At just 5 g, it screws onto the standard 28 mm thread found on most PET bottles as well as soft flasks like Platypus and CNOC, so there's no separate container to carry — just the water bottle already in the pack. The nozzle is shaped to produce a strong, steady stream rather than a weak trickle, which is the usual trade-off with products in this category. It's a good example of an item where low weight and simplicity are the whole point: it replaces or significantly reduces toilet paper use, useful on longer trips where waste management is a real constraint. The catalog entry for this product doesn't yet include detailed specs beyond thread compatibility and weight, so it's worth double-checking your own bottle's neck diameter before relying on it. For thru-hikers and anyone managing hygiene away from running water, it's a gram-level addition with outsized practical value.
