Employing weather-resistant 650+ water-resistant duck down insulation and lightweight fabrics, the Sea to Summit Women’s Trek II sleeping bag effectively balances weight and thermal efficiency. It’s suggested temperature rating of 18 degrees F makes it ideal for 3-season use.
Catering to female campers and backpackers, Sea to Summit’s women-specific sleeping bags are cut shorter, provide more room at the hips, use more insulation, and strategically distribute insulation in the foot and torso to address areas where women frequently point to heat loss. Adding an extra measure of comfort, they even include a layer of Thermolite at the feet!
The bag is insulated with 650+ fill Ultra-Dry Down insulation. Renowned for their efficiency in retaining heat and compressible properties, the feathers and fibers of down have an incredibly soft, comfortable feel and, despite advances in synthetic materials, continue to provide the best warmth-to-weight ratio of any insulation available. The one weakness of down insulation is that it loses much of its ability to maintain warmth when it gets wet, but the Women’s Trek II’s insulation has been treated to add water-repellency, allow it to dry faster if it should become wet, and, most importantly, enable it to retain much of its insulating qualities even while wet. The bag’s PermaShell fabric also has a DWR treatment to further protect the insulation from the elements. Soft internal fabrics provide next-to-skin comfort.
The tapered rectangular shape of the bag provides a bit more comfort than restrictive mummy bags while still ensuring thermal efficiency. This efficiency is bolstered by horizontal baffles and 3D side walls that provide the down fill with space to loft while making certain that it doesn’t migrate and create dead spots. A contoured, insulated hood adds additional warmth and has built-in adjustability to draw it close in cold temperatures. An insulated draft tube behind the full-length zipper helps to keep cold air from finding its way inside. That zipper continues around the foot of the bag, enabling it be unzipped completely for use as a blanket or comforter. A zippered internal pocket is a great place to stash valuables.
Available in your choice of Regular (fits to 5’ 7”) and Long (fits to 5’ 10”) size options, each Sea to Summit Women’s Trek II sleeping bag includes an Ultra-Sil compression bag and a hybrid storage cell/laundry bag.
