Camping Helikon-Tex Fold-A-Cup Wildo — Green

The Helikon-Tex Fold-A-Cup Wildo is the original Swedish collapsible cup, patented for the Swedish military, made from BPA-free polymer with a capacity of 250 ml. It weighs 24 g and folds down to just 9.5x2.5x7 cm, fitting easily into any side pocket of a pack or a trouser pocket without any noticeable bulk.

The folding construction is both its main advantage and the trade-off worth knowing: when open it reaches its working dimensions of 10x5x7 cm, enough to hold a hot drink or rehydrate a ration, but the flexible wall does not offer the same stability as a rigid cup on uneven surfaces. Anyone prioritising minimum weight and packability will get the most out of this; anyone who wants a stable cup that stays put will find a fixed-body design more practical.

The material handles boiling water and sub-zero temperatures without deforming, and tolerates prolonged compression — useful when it has been sitting at the bottom of a pack for days. Made in Sweden, with a patented design that has not changed because it does not need to.

Key points

• Capacity of 250 ml: enough for a hot drink or to rehydrate freeze-dried food in the field.
• Weight of 24 g and folded dimensions of 9.5x2.5x7 cm: disappears into any pocket without giving up usable space.
• Certified BPA-free polymer: no leaching of harmful substances even with boiling liquids or extended use.
• Resistant to heat, frost and compression: does not degrade if left folded under pressure for weeks.
• Patented Swedish design adopted by the Swedish military: reliability proven in the field, not just in the lab.
