Show Description

A minimalist shelter for fast and light adventures, the Helium Bivy is made of lightweight waterproof-breathable fabric that brings the weight down to 510g. Leave the optional hooped pole behind, and your shelter weighs a scary-light 453g. The clamshell design opens up wide, and if you're sleeping out at lower elevations in warm temperatures, removable no-see-um mesh allows you to add ventilation.

  • Upper fabric is 2.5-layer nylon Pertex Shield with a clear laminate upper.
  • Floor is tough nylon with an anti-fungal coating to prevent mildew.
  • Fully seam taped and completely waterproof-breathable.
  • 5 stake loops and one guy-line loop.
  • High volume toe allows you to store your boots and gear.
  • Removable no-see-um netting at opening.
  • Single shock-cord Delrin pole.
  • Fit thick sleeping mats and lengths up to 178cm; straps hold your pad in place.
  • Small internal mesh pocket.
