On the Trail Vest in Caron Simply Soft – Knitting Pattern Summary

About This Pattern

The On the Trail Vest is a free, downloadable PDF knitting pattern designed by Andrea Graciarena and published by Caron. It produces a classic pullover-style waistcoat — a sleeveless, body-hugging vest suitable for layering on outdoor adventures or casual everyday wear. The design is rated intermediate in difficulty, making it an excellent project for knitters who are comfortable with basic shaping, markers, and simple colorwork techniques. The finished garment features a distinctive mosaic-patterned collar that adds visual interest and a polished finish to an otherwise clean, structured silhouette.

Sizing and Fit

The pattern is written in five sizes, ranging from Small through 2XL, offering a generous range of finished bust measurements:

• Small: 36 inches (91.5 cm) bust, 24 inches (61 cm) length
• Medium: 40 inches (101.5 cm) bust, 25 inches (63.5 cm) length
• Large: 44 inches (112 cm) bust, 25.5 inches (65 cm) length
• XL: 48 inches (122 cm) bust, 27 inches (68.5 cm) length
• 2XL: 52 inches (132 cm) bust, 27.5 inches (70 cm) length

All measurements are given not including the collar, so knitters should account for additional length when the collar is added. The graduated length across sizes ensures a proportional fit for a variety of body types.

Materials: Yarn and Needles

The pattern calls for Caron Simply Soft, an aran-weight yarn available in a wide range of colours. Simply Soft is a well-loved acrylic yarn known for its soft hand, easy care, and consistent stitch definition — qualities that make it ideal for a structured garment like this vest. Each skein contains 288 metres (315 yards) and weighs 170 g (6 oz).

Two contrast colours are used in this pattern:

• Contrast A: Caron Simply Soft in Dark Sage (shade 9707)
• Contrast B: Caron Simply Soft in Chocolate (shade 9750)

The combination of a muted green and a rich brown gives the vest its earthy, trail-ready aesthetic. A circular needle is required to accommodate the large number of cast-on stitches, though the body is worked back and forth in rows rather than in the round. Stitch markers are also needed to manage side shaping and section divisions.

Construction Method

The On the Trail Vest is constructed in a practical, seamless-friendly manner that minimises finishing work. Key construction details include:

• The body is worked in one piece from the lower edge upward, all the way to the armhole, which reduces side seaming
• At the armhole, the work is divided into three sections: the right front, the back, and the left front, each worked separately
• The collar is worked separately in a mosaic stitch pattern after the shoulders are seamed together

This top-down division approach is a hallmark of efficient garment construction and is particularly well-suited to intermediate knitters looking to build their skills in shaping and garment assembly.

Stitches and Techniques Used

The pattern employs a clear and well-defined set of stitches and techniques. Knitters working on this vest will use:

• Seed stitch — worked for 7 rows at the lower edge to create a neat, non-rolling border. Seed stitch alternates knit and purl stitches in a checkerboard arrangement and is a classic choice for hems and edgings
• Stockinette stitch (St st) — the primary body fabric, created by knitting on right-side rows and purling on wrong-side rows, producing a smooth, classic kn
