    The best bag liner from a great outdoor retailer

    2 years ago
    [This review was collected as part of a promotion.] I appreciate the customer service-always delivered promptly and great communication. The product is just what I was looking for-a small light weight sleeping bag liner which keeps my expensive sleeping bag clean and adds a little warmth but doesn’t restrict movement.

    [This review was collected as part of a promotion.] Love this liner for my 30 degree down quilt! Warm, and so comfortable. I know it will keep my quilt cleaner, and will easy to wash. Will use it on my At thru hike in 2024.

    Sleeping bag protection

    [This review was collected as part of a promotion.] Comfortable sleeping bag protection plus add warmth. After a grimy day of hiking or biking and not being able to shower the sleeping bag liner is not only comfortable but keeps my expensive sleeping bags clean and in good shape. Easy to eat a liner after each trip and because of it I've never needed to wash a sleeping bag

    Wrong version sent! PICTURE DOESN"T MATCH TITLE!

    Wrong version sent! TITLE NEEDS CHANGING TO MATCH PRODUCT SHOWN! Picture is of the (red) Compact Plus, so that is what I assumed I was ordering/getting... Was sent regular reactor (that is no longer listed on website) based on title not picture! * even the labelling on bag is different, as it doesn't have the large stitched rectangular, but a little flap and the colour is a dark 'golden rod'. ** the Reactor Extreme's title matches its picture. Either way, something is wrong/misleading, as the product shown and the item received; due to title, needs rectifying. * also needs changing on Atmosphere! I don't recommend investing in this product unless this marketing issue is fixed to match product with title. Product itself looks sound... packs real small and is light 3 -stars just because

    No, I do not recommend this product.
