Summer Expanda Panel adds 40cm of extra chest width to your sleeping bag. Fits both Standard and Extra Long Softie Sleeping Bags

Available for all UK made bags this zip-in-wedge adds extra chest room (Sleeping bag not included)
 
Please note: As expanda panels are made at a different time in production to the sleeping bag, occasionally, the Expanda can appear up to 10cm longer or shorter than the sleeping bag. Although the zip tape length is exact, there is a variation on the amount of coil per zip, which the zip manufacturer explains as the “expected tolerance”.
