You’ll be deep in a doze, no matter what the change of temperature is with the Sea to Summit Basecamp Bt3. This model takes everything you love about the traditional Basecamp sleeping bag range, but swaps out down for synthetic which makes it perfect for adventurers who want full features, without the strain on your wallet. 

Insulated with Sea to Summit’s Thermolite fibre, you can be more carefree with this bag, as the synthetic fill makes it easier to clean and take care of. One of the most charmingly versatile sleeping bags on the market, Sea to Summit have added every feature to ensure you can use this bag in all weather conditions.

The clever design lets you adjust the bag to your preferred sleeping arrangement – so you can unzip the side for temperature control, unzip both sides to use it as a quilt with a closed footbox, or you can have your feet hanging out while staying completely zipped up. You can also use it with both sides undone like you would at home in your own bed, or remove the top for very warm evenings. If you’re travelling light, just take the top part with you as the bottom will hook onto your mat and keep it in place all night.

Best of all, this bag has a pillow attachment and quilt loops to secure your whole sleep system together – so you can toss and turn all you like and wake up without a crook neck. A comfortable and soundless sleep in the elements is always possible with the versatile Basecamp BT3 Bag from Sea to Summit.
