Questions
How is the Women's Spark cut differently?
It is narrower at the shoulders, which saves weight, and wider between the hips and knees to allow a natural side sleeping position, per Sea to Summit. The company calls this a women's specific shape with body mapping, aimed at warmth and comfort without extra weight.
What do the Women's Spark ratings mean in ISO terms?
Each bag is named for its ISO comfort rating, per Sea to Summit. The 45F bag has a 45F comfort rating and a 39F lower limit. The 30F bag pairs a 30F comfort rating with a 19F lower limit, and the 15F bag pairs 16F comfort with a 5F lower limit.
What does each Women's Spark weigh in Regular?
Per Sea to Summit, the Regular 45F weighs 13.5 oz and packs to 9 x 6 x 4 in, the Regular 30F weighs 20.6 oz and packs to 11 x 7 x 4 in, and the Regular 15F weighs 32.8 oz and packs to 16 x 9 x 6 in. Long versions add a little weight.
Which heights do the Women's Regular and Long lengths suit?
Sea to Summit recommends the Regular for women up to 170 cm (66.93 in) and the Long for women up to 185 cm (72.83 in). Regular bags measure 181 x 71 cm (71 x 28 in), and Long bags measure 196 x 76 cm (77 x 30 in), across all three ratings.
Can the Women's Spark pair with a partner's bag?
