The award-winning Helium Bivy has been updated with Outdoor Research’s most durable lightweight Helium fabric with Diamond Fuse technology. This clam shell opening bivy is ideal for fast and light missions due to its incredibly low packed weight and small pack size.
From Outdoor Research:
The Helium Bivy is our lightest, best-selling, and most awarded bivy sack of all time. Incredibly quick to set up and breakdown, the ultra lightweight Helium Bivy is 14% lighter than its last generation, and has everything the outdoor minimalist needs to be comfortable.
Thru-hikers and bike packers love the Helium for its refined footprint and reduced weight, and trust it for its durable, lightweight, waterproof Pertex® Diamond Fuse technology.
A clam shell opening makes it easy to get in, get out, and resists wear and tear for future seasons of adventuring to come. This is the ideal shelter for minimalists who are looking to trade weight for speed, agility, and performance.

EMS is a Plastic Free Retailer
From 1st June 2019 no new plastic will be used in any order shipments.
We now use recycled craft paper wadding, paper based adhesive tape, card boxes and double wall paper bags for all our order shipments. No new plastic is used at all.
We'll continue to reuse the bubble wrap and other plastic packing materials our suppliers send to us as reusing is still better than recycling.

Question: What is the EMS returns policy?
Answer: If you don't like it send it back for a refund.... no problem! Please read on for terms and conditions.
In line with current health and safety guidelines, we reserve the right to refuse any items that are (for whatever reason) not returned to us in a clean and hygienic condition.
Goods with manufacturing faults can be returned for a full refund (including delivery and standard return postal charges of up to £7.50) if the item, after later inspection by us, is proven to have been faulty and returned to us within 30 days from the date of purchase.
Please check all goods on arrive to ensure they have not been damaged in transit and report any damaged goods as soon as possible after receipt and within 14 days.
Please email or call and ask us which return service to use as we can only refund for the service we recommend.
Please note that inflatables such as sleeping mats are not considered to faulty if they become punctured and are not covered by the manufacturers warranty in this event.
If the goods have been supplied as requested but are unwanted they can be returned within 30 days from receipt of goods for a full refund provided they have not been used and are in a resealable condition with all of the manufacturer's labels and packaging intact.
Items ordered in November or December as Christmas presents can be returned to us at any time in January.
If you would like to exchange for an alternative size we will supply replacements subject to stock availability. You will have to pay to have the goods sent back to us, but we won’t charge you any shipping for your first replacement item.
All items returned must be unused and with their original labelling and packaging intact (unless faulty).
How To Send Returns.
1). You will need a returns number and a returns address. Please use the 'Contact Us' form from the 'Contact Us' page (found in the footer of this page). Send us your order number and reason for return. We will issue a returns number and returns address for one of our UK warehouses. (Please Don't ship your returns to our office address in Cheltenham as we don't keep any stock there and there might not always be someone there to sign for your package).
2). For New and Unused returns please include all the Manufacturer's Packaging and Labels, otherwise we can't return the item to stock.
3). Carefully pack the product so it survives its journey and send it to the address we provide. We recommend a postal service with a signature on receipt.
