Therm-a-Rest Boost 650 32F/0C Down Sleeping Bag Regular Wide - Meadow Green

From backpacking trips to car camping excursions, the Boost 650 provides the dreamy comfort you need to sleep well outdoors. With an innovative design that allows you to adjust its shape and add warmth when needed, the Boost is one of the most comfortable and versatile sleeping bags ever made. The semi-rectangular shape gives you considerably more internal space than a mummy bag—you’ll feel unrestricted and free to sleep in whatever position you want all night long. But more space demands more body heat to warm it up and cold isn’t comfortable. That’s where WarmZip comes in. Zipping up the WarmZip centre zipper transforms the shape of the Boost 650 from a semi-rectangular bag to a thermally efficient mummy bag. It pulls the 650-fill down around your body and reduces the amount of space your body needs to heat. WarmZip gives you the power to add up to 10F/6C to the Boost’s temperature rating. Standard Therm-a-Rest features like a puffy draft collar, a draft tube along the entry zipper line and a cinchable hood round out the Boost’s bliss-inducing comfort.
The Boost 650 was created to provide comfort whether you’re drifting off to sleep, already asleep, or fully awake and relaxing in your tent. The armholes let you easily reach the WarmZip without needing to open the side zipper. They also allow you to grab your belongings, read, play cards, or high-five friends without leaving the cosy warmth of your sleeping bag. If you get too warm, you can ventilate through the armholes or sleep comfortably with just your arms outside. Additionally, the two-way side zipper lets you ventilate around your torso or feet. Every zipper on the Boost features a durable YKK anti-snag pull to prevent snags and tears.  
Despite all this comfort, the Boost 650 isn’t bulky or heavy. It was designed specifically for backpacking, with carefully selected materials and design to keep it lightweight, packable, and effective in various backcountry conditions. Zoned Insulation uses 650-fill hydrophobic down in key warmth areas (top, core, and shoulders) while reducing it where it’s less useful (bottom), allowing the Boost to provide more warmth with less down. The shell and liner are made from 100% recycled nylon, chosen for its lightness and soft feel. The PFAS-free DWR coating and hydrophobic down ensure the Boost stays warm and comfortable even in wet conditions.

At FreshAirJunkie we understand that when you order a product you want it to arrive as soon as possible and with the minimum of fuss, so when an order is received by us, we promise to try our best to dispatch it within 24 hours (Monday to Friday). 

Orders received on a Saturday or Sunday will be packed on the day and dispatched on the following Monday. 

To cut costs for our customers, we dispatch all items via a Royal Mail 48 hour Tracked Service. For larger items or high value items, we mainly use Parcelforce. The estimated delivery time for 2nd Class is delivery by the 3rd working day after posting. Whilst Royal Mail state that most items will be delivered within these time frames it can occasionally take up to 15 days after the due delivery date. 

Unfortunately once the items are with Royal Mail we lose any influence and control over their delivery. 

We ask all customers to be patient when waiting for their products to arrive. If for some reason you have not received your product within a reasonable length of time then please don't hesitate to contact us at: freshairjunkie@hotmail.co.uk so we can look into it for you.

For any items where tracking shows delivered, but the customer denies receipt, the customer agrees to fill in a Royal Mail 'Denial of Receipt' form, so the delivery can be investigated.

Please note, if your parcel arrives opened, or damaged, please check the contents before accepting delivery. Any problems should be noted with the delivery person, or parcels should be refused, Once you accept delivery, we are unable to make a claim to Royal Mail for loss.

It is very important that you provide a delivery address that is accessible and where someone will be in to receive the item, or there is a safe place agreed with Royal Mail for your deliveries.

We do not deliver to Parcel Lockers.

All items will be delivered to the address, and not guaranteed to be handed over in person.

They still however charge us for the additional service, and we still process the same day and dispatch the same day. We can therefore not refund any expedited order costs, if delivery times are missed.

We also reserve the right to choose the most appropriate shipping service as we see fit, which may result in a higher charge to cover for example, added insurance cover.
